STAHL, Circuit Judge.

Plaintiff-appellant Johanna Thomas appeals the grant of summary judgment to defendants-appellees Contoocook Valley School District and School Administrative Unit 1 (collectively, the "School Board") on her claim that her teaching contract was not renewed in violation of the Americans with Disabilities Act ("ADA"), 42 U.S.C. § 12101 et seq. This appeal involves the extent to which findings made during state administrative proceedings in which Thomas contested her dismissal have preclusive effect in federal court. The district court found that factual findings made by the defendant School Board, which were reviewed by the New Hampshire State Board of Education ("State Board") and the New Hampshire Supreme Court ("NHSC") conclusively established that the reason for her non-renewal was nondiscriminatory. We disagree and reverse.

I. Background

On a motion for summary judgment, we recite the facts in a light most favorable to the non-movant, Thomas. DeNovellis v. Shalala, 124 F.3d 298, 305-06 (1st Cir. 1997).

Thomas began teaching in the Contoocook Valley School District in the early 1980s. From 1987 to 1989, Thomas received generally satisfactory evaluations of her performance, which described her as "a teacher who is building a solid program in her room as well as solid relationships with the children and their parents." These evaluations, which were conducted by various administrators, commended Thomas for such attributes as her enthusiasm, desire to improve, and ability to keep classroom interest high. The evaluations noted some problems, however, including her failure to arrive at school "during the expected time in the morning before school begins," and some difficulties with "large group classroom management." A later evaluation concluded that these problems had been resolved.

In September 1989, Thomas underwent throat surgery for the removal of polyps from her voice box, which made her voice sound persistently hoarse. In addition, she was forced to take an extended sick leave and missed a substantial amount of the 1989-90 school year.

When Thomas returned, she had problems arriving at school on time. On December 12, 1990, Principal Anita Willard (now Prudhomme) wrote Thomas a note complaining that Thomas was persistently late to school and warned her that Willard "just couldn't have this happening in this school." On March 19, 1991, Willard informed Larry Bramblett, the Superintendent, of her problems with Thomas. In addition, Willard excoriated Thomas in a letter to her, in which she wrote:

This letter is to inform you that the issue surrounding your lateness to school, meetings, and duties has reached a point where I can no longer handle it. . . .

On Monday when you arrived at 9:15 with no excuse, I had already talked on the phone with a parent who wanted to talk to you before school about her child. . . . Your class when it arrived was unsupervised, you know that this has happened before, and given the nature and age of your children this is totally unacceptable. The other problem concerns the staff meeting that was changed to fit your schedule. . . . [E]veryone else was on time except you. . . .

I think you understand that our job requires us to be here at certain hours, cover our school duties, attend meetings on time, pass in work such as testing, budget items, report cards etc. It often feels to me that it requires too much supervision on my part to see that you do your job.

The letter warned that Bramblett was expecting a call from Thomas within a week to discuss the situation. The next week, Bramblett sent a letter to Thomas, saying that her job was "in jeopardy" and that "her attendance particularly tardiness has placed your teaching performance in an unsatisfactory condition." He warned that "another incident regarding your classroom attendance or unfounded absenteeism will result in . . . immediate dismissal."

During the next school year, Thomas's teaching performance was observed and evaluated in the normal course of evaluations. The school district utilized teacher performance observation forms that allowed an observer to rate a teacher "satisfactory," "not satisfactory," or "not observable" in regard to twenty different attributes of classroom performance, such as "demonstrates knowledge of subject matter" and "prepared in advance of lesson." During the 1991-92 school year, Willard conducted observations of Thomas's classroom performance on February 7 and 12, 1992. She rated Thomas "satisfactory" or "not observable" in all categories. Thomas's overall evaluation for the 1991-92 school year, also conducted by Willard, recommended that Thomas be renewed for the following year. The evaluation suggested that Thomas work on "classroom management, learning techniques to keep all students focused and on task," but commended her for improving her attitude toward "non-instructional issues," such as paperwork, due dates, working with other staff, and testing duties.

Subsequently, on several occasions after Willard recommended renewal, Bramblett expressed concern over Thomas's voice problems. He wrote Thomas on March 13, 1992, explaining that a number of parents had complained about her teaching performance and that at least one was "concerned about her child understanding you with your recent voice problems." On May 21, 1992, Bramblett explained in a memorandum to Thomas that he had called Thomas's doctor "regarding the chronic or apparent chronic condition of your voice" and noted parents' complaints "regarding student comprehension from your verbal instructions." On June 6, 1992, Thomas saw her doctor, who described her condition as "chronic laryngitis," and recommended "intensive speech therapy with a change in voice habits that reduces strain on the vocal chords." On June 17, 1992, Bramblett criticized Thomas for not obtaining medical advice in a timely manner and tied her voice problems to her classroom performance. He stated:

I have felt all along that you have not grasped the seriousness of the matter before you. Although I recommended seeing your doctor a month ago, only now have you decided to seek medical advice regarding your voice. My classroom observations still leave me uncertain as to your specific problem — control issues because children cannot detect the inflection in your voice, or if control is a chronic condition unaffected by a physical problem. . . . I again urge you to consider Long [sic] term disability insurance and taking at least a year off before I begin evaluating your tenure in this district.

He then informed her that she was being transferred from Hancock Elementary school, where she had taught a combined grade class, to Antrim Elementary School, to teach in a second grade class. On August 3, 1992, Bramblett, in a letter summarizing a recent meeting between them, required Thomas to get a second opinion on her voice, and a "general release" certifying both that her voice "ha[d] improved to the point that [she could] communicate in normal fashion with children ranging in ages from six to nine years old" and that her condition "is not expected to regress." Bramblett threatened that her failure to obtain these assurances "would result in a temporary or permanent loss of employment."

Thomas subsequently obtained a letter from the Massachusetts Eye and Ear Infirmary which recounted her "persistent hoarseness," but noted that her "phonation" had improved due to speech therapy, and expressed the hope that "an entire summer of voice rest and continued speech therapy . . . as well as Vanceril inhalers . . . may significantly improve the quality of her voice by September."

On October 27, 1992, Bramblett placed a "Warning Memo" in Thomas's permanent record file. The memo specifically incorporated by reference his prior correspondence with Thomas concerning her voice, describing them as "evaluations," and recounted his observations during a forty minute classroom visit. He complained that "students were not well focused," and "not well engaged." He criticized a math lesson, and noted that his "concern persists about classroom control, effective use of time, and development of consistent well defined lessons." He advised, "Each of these areas define my focus for observations between now and March 1, 1993." Yet Bramblett didn't observe Thomas's class again until February 19, 1993. On February 26, 1993, Bramblett wrote a letter informing Thomas that he had decided not to renominate her "at the School Board renomination meeting on March 16, 1993," explaining that his "last observation of February 19, 1993 showed no substantial improvement of the concerns expressed in November." The letter cited three reasons as the bases for his decision: a lack of classroom control, ineffective use of class time, and poor lesson development.

On March 29, 1993, Keith R. Burke, the Assistant Superintendent, notified Thomas in writing that the School Board had not re-elected her for the upcoming school year, and informed her that she had the right under N.H. Rev. Stat. Ann. ch. 189:14-a to a hearing before the school board and to obtain a statement of reasons, in writing, for the Board's decision not to re-elect her. His letter also advised Thomas that the School Board would issue its decision fifteen days after the close of the hearing. Thomas asserted her right to a hearing, which was held on August 26, 1993.

At the hearing, Thomas was represented by counsel, introduced documentary evidence, called witnesses, and cross-examined Bramblett and Willard, both of whom testified against her. A number of parents testified on Thomas's behalf, describing positive experiences their children had had with Thomas. The rules of evidence were relaxed. After reviewing the evidence, ten of the eleven School Board members voted unanimously to approve their non-renewal decision (the eleventh board member was not in attendance at the vote). As required by chapter 189:14-a, the School Board provided a statement of reasons for its decision, which the Board denominated as "findings": (1) Thomas had adequate notice of Bramblett's concern about her performance; (2) Thomas's tardiness had no direct bearing on her non-renewal and "the tardiness ceased after Bramblett's warning of March 27, 1991"; (3) the Board characterized as "incredible" Thomas's testimony that she was not aware, prior to Willard's 1990 letter, of the requirement that she be in her class by 8:30 a.m.; (4) Thomas's health had "no direct bearing" on her non-renewal; (5) Willard had "significant concerns" about Thomas's effectiveness, which the Board found "persuasive"; and (6) although many parents and their children had positive experiences with Thomas, the Board had to give Willard's and Bramblett's testimony greater weight. Based on these stated reasons, the School Board concluded:

The Board finds . . . that the administration has proven its case by a preponderance of the evidence. The Board finds that Mrs. Thomas's classroom performance suffered from significant problems, including in the areas of lack of discipline, poor use of time and poor development of lessons, which issues the Board finds to be inextricably inter-related. The Board finds that it lacks sufficient evidence to determine whether or not Mrs. Thomas's voice was a factor in the problem of classroom control.

Plaintiff appealed the School Board's decision to the State Board pursuant to N.H. Rev. Stat. Ann. ch. 189:14-b, asserting that the School Board's stated reasons were not supported by substantial evidence. Specifically, in regard to the role that her voice problems played in the non-renewal decision, Thomas asserted that:

The school board improperly relied upon criticisms of Mrs. Thomas related to her voice problems, despite clear evidence that Mrs. Thomas's voice problems did not interfere with her ability to teach, and to that effect the school board erred when it concluded that "the issue of Mrs. Thomas's health had no direct bearing on her non-renewal."

The State Board has administrative authority to review the School Board's decision, and to reverse that decision and order reinstatement if the "substantial rights of the teacher have been prejudiced because the administrative findings, inferences, conclusions, or decision are . . . in violation of constitutional or statutory provisions . . . [or c]learly erroneous in view of the reliable, probative, and substantial evidence on the whole record." N.H. Code Admin. R. Ed. 202.06(e)(1), (5). The State Board interprets this regulatory authority as authorizing a limited review to determine whether (1) a non-renewed teacher has received the required procedural process (that is, notice and hearing); (2) the School Board's findings of fact supporting the reason for this dismissal are clearly erroneous; and (3) the "reasons given are arbitrary, capricious or contrary to law." In re Carolyn Ellis v. Dover Sch. Bd., Findings and Recommendations of Review Board, at 4-5 (N.H. Bd. of Ed. undated slip opinion) (emphasis added), aff'd, No. 94-509, slip op. (N.H. February 2, 1996) (referred to as the "Ellis decision"). Notably, there are no substantive standards governing teacher renomination or re-election set forth in N.H. Rev. Stat. Ann. ch. 189:14-a. See id. at 2. Thus, it seems that a school board may refuse to renew a teacher's contract on any basis so long as the reasons it provides are supported by evidence and are not contrary to law.

When Thomas appealed to the State Board, the parties agreed to present her arguments to a hearing officer (rather than to a three person review board), who permitted each party to present two witnesses and to cross-examine the other party's witnesses. The hearing officer reviewed the record developed before the School Board, including the hearing transcript and the submitted exhibits. He recommended to the State Board that it uphold Thomas's non-renewal. The hearing officer concluded that the School Board's stated reason for Thomas's non-renewal — that her classroom performance suffered from significant problems — was, "in accordance with the Ellis decision, . . . entitled to due deference if reasonably based on sufficient evidence, which it was." At the same time, however, he vacated the findings concerning the effect of Thomas's voice on the School Board's non-renewal decision. The hearing officer explained his decision as follows:

[T]he Board found "that the issue of Mrs. Thomas' health ha[d] no direct bearing on her non-renewal", and yet further on in the decision it concluded . . . that there was not "sufficient evidence to determine whether or not Mrs. Thomas' voice was a factor in the problem of classroom control." These are inconsistent findings.

. . . .

Clearly, Mrs. Thomas' voice problems since her 1989 vocal chord surgery have been a persistent concern of the district and some parents, generally expressed to Mrs. Thomas in terms of her apparent difficulty communicating effectively with her students, a critical component of classroom control. Counsel for the district acknowledged at the hearing before the undersigned that the ability of students to clearly hear what their teacher is saying before they can hope to comprehend what she is attempting to teach them . . . is fundamentally necessary in any classroom. Mrs. Thomas' perceived deficits in this regard have been, he argues, a legitimate source of concern of the district. Whether the extent of the district's reliance on the concern in reaching the non-renewal decision here was permissible under RSA 354-A:7I [state discrimination law] is a fact-sensitive question best left to the Commission for Human Rights before which Mrs. Thomas currently has pending an employment discrimination claim. While that agency is best suited to determine the legitimacy of the district's position regarding Mrs. Thomas' voice impairment, it is clear from the record in this matter that her health problems were a factor in the Superintendent's non-renewal decision.

The hearing officer concluded that the School Board's finding that Thomas's voice had no direct bearing on her discharge was "not supported by the record."

After the State Board requested additional explanation, the hearing officer expounded on his bifurcated recommended decision in a letter that was incorporated into the State Board's final decision.

Four times between March and August 1992 the Superintendent wrote to Mrs. Thomas, linking her voice impairment to what he perceived to be her problems controlling her classroom. . . .

The evidence . . . at a minimum suggests that Mrs. Thomas' voice impairment was felt by the Superintendent to very likely contribute to her inability to control her classroom and to be comprehended by students. . . .

At best, the local school board should have concluded that it lacked sufficient evidence to determine whether her health had a direct bearing on her discharge.

In a 4 to 3 vote, the State Board accepted the hearing officer's recommended decision and affirmed the decision of the School Board. The School Board adopted the hearing officer's findings as its own, including the hearing officer's determination that the discrimination issue was best left to the New Hampshire Commission for Human Rights ("Commission").

Thomas petitioned for certiorari to the NHSC, raising four questions, including "Whether a school district may violate its own evaluation policies and thereupon non-renew a teacher for reasons apparently related to the teacher's speech disability." The NHSC granted Thomas's petition to hear this question, and summarily affirmed the State Board's decision without explanation. After obtaining the requisite right-to-sue letter from the EEOC, plaintiff filed suit in the United States District Court for the District of New Hampshire, alleging that the School Board's decision not to renew her teaching contract violated the ADA.

The defendant moved for summary judgment on the ground that plaintiff's claim was barred by the doctrine of collateral estoppel. The district court granted defendant's motion. The court reasoned that, under Price Waterhouse v. Hopkins, 490 U.S. 228, 242 (1989), "an employer may escape liability by proving that it would have engaged in the challenged conduct even if it had not taken disability into account." Relying on the legal proposition that "the findings of administrative agencies may be accorded preclusive effect under the doctrine of collateral estoppel," the district court "accorded collateral estoppel effect to the School Board's findings of the reason for Thomas's termination," which, in the court's view, precluded her from establishing that unlawful discriminatory animus was the "but for" cause of her termination. As the district court explained:

The School Board's findings, which plaintiff is estopped from denying, establish that the superintendent would have fired Thomas regardless of whether or not he took her disability into account. The Board reportedly found "that Mrs. Thomas' classroom performance suffered from significant problems, including in the areas of lack of discipline, poor use of time and poor development of lessons." The Board of Education pointed out that "the local board did have evidence that Mrs. Thomas's teaching performance in the three areas of classroom control, lesson planning and use of time was considered deficient by her teaching principal." Based on these findings, it is clear that Thomas's poor performance provided sufficient grounds to terminate her, regardless of her disability.

See No. 96-414, slip op. at 5-6 (D.N.H. Nov. 5, 1997). Thomas appeals.

II. Discussion

Plaintiff contends that the district court erred by holding that the stated findings of the School Board established conclusively the reason for her dismissal. She argues that, although the School Board provided a statement of reasons for her dismissal, the issue of whether Thomas had been the victim of discrimination was not actually decided in the state proceedings. As a result, she maintains, there was no finding with regard to the critical factual dispute in the case, and she is therefore not collaterally estopped from litigating that issue in federal court. We agree.

28 U.S.C. § 1738 governs the preclusive effect of state judicial proceedings in subsequent federal court actions and extends to the federal courts the principles embodied in the Full Faith and Credit Clause of the Constitution. "Section 1738 requires federal courts to give the same preclusive effect to state court judgments that those judgments would be given in the courts of the State from which the judgments emerged." Kremer v. Chemical Constr. Corp., 456 U.S. 461, 466 (1982). In the absence of a state court judgment, section 1738 does not apply, and whether state agency findings are accorded preclusive effect in a subsequent civil rights action is a question of statutory interpretation: did Congress, in enacting the relevant civil rights statute, intend to displace federal common-law doctrine that accords preclusionary effect to state administrative findings? See Astoria Fed. Sav. Loan Assoc. v. Solimino, 501 U.S. 104, 108 (1991)("[T]he question is not whether administrative estoppel is wise but whether it is intended by the legislature."); University of Tenn. v. Elliot, 478 U.S. 788, 794-96 (1986); Kremer, 456 U.S. at 470 n. 7 (dictum). It is now settled, however, that State agency findings that are not reviewed by a state court are not entitled to any preclusive effect in a subsequent action under Title VII, see Elliot, 478 U.S. at 795-96, or the Age Discrimination in Employment Act of 1967 ("ADEA"), see Astoria, 501 U.S. at 111-12. As the Supreme Court has observed, Congress could not have intended to accord preclusive effect to unreviewed administrative findings in a subsequent Title VII action because under the federal remedial scheme, even the EEOC is required to give only "substantial weight" to state proceedings. See Kremer, 458 U.S. at 470 (quoting 42 U.S.C. § 2000e-5(b)). Though this review ensures that state agency proceedings are not ignored, this standard plainly leaves room for the EEOC to depart from state administrative findings — which would be "pointless if the federal courts were bound by such state agency decisions," id. at 470 n. 7; see Elliot, 478 U.S. at 795 (similar); cf. Astoria, 501 at 110-12 (finding that the filing provisions of the ADEA "assume the possibility of federal consideration after state agencies have finished theirs.").

In Kremer, the plaintiff had filed a discrimination claim with the EEOC, which referred his discrimination charge to the New York State Division of Human Rights ("NYHRD"), the state agency charged with enforcing state discrimination law. 456 U.S. at 464. The NYHRD found that there was no probable cause to believe that the plaintiff's employer had engaged in the discriminatory practice of which the plaintiff complained; the NYHRD Appeals Board affirmed this finding. See id. The plaintiff then filed a petition with the Appellate Division of the New York Supreme Court, which upheld the adverse administrative decision. See id. This judicial determination, the parties agreed, barred the plaintiff from bringing any action "'based upon the same grievance' in the New York courts." Id. at 466-67 (citing N Y Exec. Law § 300 (McKinney 1972)). The Appellate Division's affirmance of the agency determination brought section 1738 to bear when the plaintiff brought his claim in federal court. See id. at 466. Because under New York law the plaintiff was barred by the state court judgment from pursuing his claim in state court, so too was he barred in federal court.

In this case, Thomas appealed the State Board's decision to the NHSC, and the NHSC entered judgment affirming that decision. Under Kremer, we must determine whether the NHSC's summary affirmance of the State Board's decision bars Thomas from pursuing her discrimination claim under New Hampshire law, and hence, by operation of section 1738, in federal court. See, e.g., Baez-Cruz v. Municipality of Comerio, 140 F.3d 24 (1st Cir. 1998). At the outset, we note that the controlling facts in this case are unusual. The School Board made two "conclusions" that are pertinent to our discussion: (1) that Thomas's classroom performance suffered from significant problems and (2) that Thomas's health (i.e., her voice) "had no direct bearing on her non-renewal." The State Board ruled that the first finding was not "arbitrary and capricious," and thus concluded that there was sufficient cause to uphold the termination, but vacated the second finding, and referred the question of disability-based discrimination to the Commission. The NHSC summarily affirmed the State Board's bifurcated decision. The question presented is thus whether the State Board's judicially reviewed decision that sufficient cause existed to warrant Mrs. Thomas's non-renewal, viewed in conjunction with the State Board's deferral of whether she was subject to discriminatory treatment, precludes the plaintiff from litigating the actual reason for her dismissal.

Our reading of New Hampshire law persuades us that, unlike Kremer (in which there was no dispute that New York law barred any subsequent action based upon the same grievance), the NHSC's affirmance of the State Board's decision here would not preclude Thomas from litigating the reason for her non-renewal before the Commission and then in state court. Our analysis is guided by Petition of Kenneth Dunlap, 134 N.H. 533 (1992), in which the NHSC ruled on the preclusive effects of teacher tenure proceedings brought under chapter 189:14-a. Dunlap, a high school teacher, was informed by his Superintendent that his contract would not be renewed for the following year. As Thomas did here, Dunlap contested the non-renewal before the local school board under chapter 189:14-a, which, after a full hearing, stated as its reason for non-renewal the "deleterious effect of [Dunlap's] numerous absences" that were due to his chronic asthma. Id. at 536. Dunlap then requested a hearing before the review board of the State Board of Education, arguing that the local school board had discriminated against him in violation of handicap and equal protection laws. See id. at 537. Dunlap's primary response to School Board's decision was that his asthma had abated since he had obtained proper treatment and, therefore, the objectionable absences would not occur in the future. The State Board upheld the local board's decision, finding that Dunlap's "record of excessive absences was sufficient for the [school board] to conclude he was not able to perform his responsibilities."

Dunlap then appealed to the NHSC, claiming that "the State Board acted illegally in upholding a discriminatory local board decision." Id. at 538. The NHSC agreed, reversed the State Board's decision, and ordered plaintiff reinstated, holding that the school board's stated reason for its decision violated New Hampshire disability discrimination law because it impermissibly relied only on evidence of Dunlap's past impairment, without considering the likelihood of his future impairment. See id. at 542-44 (citing N.H. Rev. Stat. Ann. ch. 354-A:8).

After reaching the merits, the NHSC addressed a question similar to that the plaintiff faces here: whether a plaintiff's invocation of the "review procedures of [chapter] 189:14-a and 14-b [forecloses] the petitioner from prosecuting a complaint before the [New Hampshire] commission for human rights." Id. at 545-46. The court held that it did not. The court's analysis primarily dealt with preclusive effect of N.H. Rev. Stat. Ann. ch. 354-A:13 (Supp. 1990) (current version at N.H. Rev. Stat. Ann. ch. 354-A:25), which sets forth rules governing the exclusivity of proceedings before the Commission:

As to the acts declared unlawful by [state discrimination law], the procedure herein provided shall, while pending, be exclusive and the final determination therein shall exclude any other action, civil or criminal, based on the same grievance of the individual concerned. If such individual institutes any action based on such grievance without resorting to the procedure provided in this chapter, he may not subsequently resort to the procedure herein.

Id. (quoting N.H. Rev. Stat. Ann. ch. 354-A:13) (emphasis added). The court held that chapter 354-A:13 did not preclude Dunlap from prosecuting a discrimination complaint before the Commission. Chapter 189 tenure hearings, the court reasoned, simply did not constitute a "civil" action, see id. 546-47, but rather served a more limited purpose.

Chapter 189 non-renewal hearings . . . are optional internal administrative proceedings which are available to teachers whose contracts are not being renewed and are aimed at developing a final, reasoned decision on the issue . . . . At the time of contesting a non-renewal decision, the teacher has not yet been dismissed but rather, has been told that he or she will not be continuing in that employment during the next school year . . . . In contrast to the panoply of remedies available upon application to a court or to the human rights commission, the school board and the State Board are limited to approving or disapproving the decision not to renew.

Id. (citations omitted). As a result, Dunlap's use of the procedures available to him under chapter 189 did not "foreclose recourse to the commission and its expertise in reviewing complaints of unlawful discrimination." Id. at 547. The NHSC also summarily rejected the argument that res judicata barred Dunlap from proceeding, noting opaquely that its "decision holds merely that the State Board's conclusion was incorrect as a matter of law and does not touch upon the issue of damages, if any for discriminatory non-renewal." Id. The court explicitly chose not to address the possibility of collateral estoppel. Id.

Here, the School Board in its brief concedes that, under Dunlap, Thomas is not statutorily precluded from pursuing her claim before the Commission, but nonetheless argues that collateral estoppel and res judicata bar Thomas from seeking another judicial (as opposed to administrative) forum for her complaint. We consider these arguments in turn.

Defendant asserts that due to the NHSC's and State Board's affirmances of the school board's non-renewal decision, the plaintiff is collaterally estopped under New Hampshire law from relitigating the reason for her termination. Defendant reasons that the State Board and NHSC both determined that Thomas's non-renewal was lawful and thus collateral estoppel bars Thomas from attempting to prove that the non-renewal was, in fact, unlawful. We disagree.

First, if we held that the State Board's conclusion that there existed "sufficient cause" for a non-renewal decision conclusively established in a subsequent proceeding whether that non-renewal decision was motivated by discriminatory animus, we would reduce Dunlap to a nullity. The Dunlap court reasoned that a teacher can contest his or her termination through chapter 189 tenure proceedings, yet still bring a complaint before the Commission, because the chapter 189 proceeding serves the limited purpose of building a reasoned decision for the non-renewal of a teacher. The ability of a plaintiff to file a complaint with the Commission (the right that defendant concedes Dunlap grants the plaintiff) would be meaningless if any adverse determination from the State Board precluded the plaintiff from litigating the reason for her dismissal before the Commission. Cf. N.H. Rev. Stat. Ann. ch. 354-A:25 (providing that the Commission is the exclusive forum for discrimination claims and that "the final determination therein shall exclude any other action").

Second, Dunlap aside, our reading of New Hampshire collateral estoppel law is contrary to the defendant's position. In New Hampshire, the party seeking to assert collateral estoppel has the burden of showing that the issue claimed to be the subject of estoppel is identical to the issue determined previously, see Morin v. J.H. Valliere Co., 113 N.H. 431, 433 (1973), and that the disputed issue has been finally resolved on the merits, see Putnam Lumber Co., Inc. v. Eddie Nash Sons, Inc., 141 N.H. 670, 672 (1997).

Here, the issue Thomas seeks to litigate in her ADA action is not identical to the issue that was determined in the state proceedings. The district court premised its opinion on the view that the School Board's stated reason established that "the superintendent would have fired Thomas regardless of whether or not he took her disability into account," and thus precluded Thomas from showing that her disability was the "but for" cause of her termination. Assuming for the sake of argument that collateral estoppel applies to the State Board's decision, the district court simply read the issue decided in that proceeding too broadly. The State Board determined only that there was "sufficient evidence" in support of the School Board's proffered reason for the non-renewal decision (that "Mrs. Thomas' classroom performance suffered from significant problems"), which is essentially a determination that there was "cause" for Thomas's non-renewal. This determination is not identical to the inquiry under the ADA: whether the defendant's decision was in fact motivated by discrimination on the basis of Thomas's voice disability. See Tolfree v. Kansas City, Missouri, 980 F.2d 1171, 1174 (8th Cir. 1992) (holding that a city personnel board determination that a termination for bad performance was "justified" did not preclude plaintiff from pursuing a Title VII "mixed-motive" claim under Price Waterhouse); cf. Petition of Gilpatric, 138 N.H. 360, 363 (1994) (holding that a superior court finding that an employee was "sufficiently disabled" to receive total disability benefits was not identical to an administrative determination whether the petitioner was entitled to "a permanent impairment award"). The claim asserted in the plaintiff's complaint is not that she was terminated without "sufficient cause" but that the Board's non-renewal decision was the result of discriminatory animus against her perceived disability. Although the State Board's determination may establish that sufficient grounds existed to terminate Thomas based on her classroom performance, it does not necessarily follow that poor classroom performance was the reason why the Board and/or Bramblett terminated her employment. Rather, the lawfulness of the School Board's decision not to renominate Thomas turns on the Board's actual motivation, as opposed to whether it could have terminated her, at the time of the non-renewal. See Bradley v. Pittsburgh Bd. of Educ., 913 F.2d 1064, 1075 (3d Cir. 1990) (holding that a state finding "that defendants could properly terminate an employee" does not establish that "the employer would have terminated the employee" in the absence of protected First Amendment activity) (emphasis in original).

Moreover, the finding of "sufficient cause" must be viewed in conjunction with the fact that the State Board explicitly chose not to decide whether the School Board and/or Bramblett impermissibly discriminated against Thomas based upon her voice disability. Understandably, the defendant attempts to characterize the NHSC's decision broadly, describing it as affirming "the decision of the State Board that the decision to non-renew was lawful." But this description does not accurately reflect the contours of the State Board's decision. The hearing officer explained that his review of the School Board's decision was limited "to the determination of whether Mrs. Thomas was accorded procedural due process by the local board, and whether that board's findings are clearly erroneous in view of the whole record, arbitrary, capricious or the result of an abuse of discretion." Under this highly deferential standard, the State Board vacated the School Board's factual finding regarding the impact of her voice problems on her non-renewal because it was not supported by substantial evidence, and referred to the Commission the question of whether "the extent of the district's reliance on [her voice disability] in reaching the non-renewal decision here was permissible."

Considering that Thomas's petition for a writ of certiorari alerted the NHSC that she had a claim pending before the Commission, it seems to us that by summarily affirming the State Board's decision, the NHSC intended no more than to hold that the State Board appropriately declined to decide whether the School Board had discriminated against Thomas, and correctly found that there was evidence in support of the school board's stated reason for its action (poor classroom performance). We see no indication that the State Board's administrative decision or the NHSC's affirmance was meant to be a final judgment on the merits of Thomas's discrimination claim and every indication that the State Board, and by implication from its affirmance, the NHSC, believed that the Commission was the proper forum to resolve that claim. To accord preclusive effect here to the State Board's decision by holding that its finding of "sufficient cause" establishes the "but for" cause of her termination would be to ignore the same tribunal's explicit decision to leave that "fact-sensitive" question to the agency "best suited" to make that determination. See Mitchell v. Humana Hospital-Shoals, 942 F.2d 1581, 1583 (11th Cir. 1991) (holding that, when it is impossible to divine from the state court judgment what was actually decided, collateral estoppel should not apply). As a result, because the State Board did not actually decide whether plaintiff's discharge was discriminatory, plaintiff would not be barred from further litigating that issue under state law. See Penrich Inc., v. Sullivan, 140 N.H. 583, 590 (1995).

For much the same reason, we find the school board's res judicata argument untenable. When a court, or as here, an administrative agency, reserves a question for further adjudication, the ensuing judgment does not generally bar subsequent determination of that question. See Restatement (Second) of Judgments, § 26(1)(b) (1982) (stating that no merger occurs to extinguish a claim when "[t]he court in the first action has expressly reserved the plaintiff's right to maintain the second action"); 18 Charles A. Wright et al., Federal Practice and Procedure: Jurisdiction and Related Matters, § 4413 (Supp. 1998) ("A judgment that expressly leaves open the opportunity to bring a second action on specified parts of the claim should be effective to forestall preclusion.") (citing cases). We see no other interpretation of the State Board's decision but as an express reservation of Thomas's discrimination claim for further adjudication. As the NHSC did not disturb the State Board's reservation when given the opportunity to do so, res judicata does not apply.

Interpreting the NHSC's summary affirmance and the State Board's decision in this manner accords with Dunlap's view that Chapter 189 proceedings are for the limited purpose of developing a record as to whether there was cause for a teacher's non-renewal (although the State Board and NHSC have the power to order reinstatement when faced with unjust terminations); the Commission is the proper forum for litigating the issue of discriminatory motivation. We note as well that, once the State Board referred the discrimination question to the Commission, any judicially unreviewed finding by the Commission as to the merits of her claim would not have been entitled to preclusive effect in federal court. See Elliot, 478 U.S. at 795; Astoria, 501 U.S. at 111-13. Unsuccessful complainants before the Commission may obtain review of Commission orders in Superior Court, see N.H. Rev. Stat. Ann. ch. 354-A:22, I, II, and federal court, see id. § 354-A:22, V (vacating any Commission order "[i]f the complainant brings an action in federal court arising out of the same claims of discrimination which formed the basis of an order or decision of the commission."). Because the NHSC's summary affirmance would not have barred Thomas from pursuing her claim before the Commission and then in New Hampshire state court, section 1738 does not preclude her from proceeding in federal court.

Finally, the defendant contends in a summary fashion that, under the collective bargaining agreement between the District and the Contoocook Valley Education Association, Thomas was required to appeal her non-renewal as specified in the grievance procedure set forth therein, which includes submitting grievances to arbitration. This argument is without merit. The agreement plainly states, "The [School] Board does not agree to binding arbitration on the following provisions. . . . Any matter for which a specific method of review is prescribed and expressly set forth by law or regulation of the State Commissioner of Education." Chapter 189 and Chapter 354 provide a method for reviewing claims for unjust terminations and discrimination. As a result, the plaintiff's ADA claim was not subject to mandatory arbitration and her failure to avail herself of those procedures does not result in a waiver of her right to bring this action.

For the foregoing reasons, the judgment of the district court is vacated and the case is remanded for further proceedings consistent with this opinion.
