Section 2855 - Causes for revocation or termination1. The charter entity, or the board of regents, may terminate a charter upon any of the following grounds: (a) When a charter school's outcome on student assessment measures adopted by the board of regents falls below the level that would allow the commissioner to revoke the registration of another public school, and student achievement on such measures has not shown improvement over the preceding three school years;(b) Serious violations of law;(c) Material and substantial violation of the charter, including fiscal mismanagement;(d) When the public employment relations board makes a determination that the charter school demonstrates a practice and pattern of egregious and intentional violations of subdivision one of section two hundred nine-a of the civil service law involving interference with or discrimination against employee rights under article fourteen of the civil service law; or(e) Repeated failure to comply with the requirement to meet or exceed enrollment and retention targets of students with disabilities, English language learners, and students who are eligible applicants for the free and reduced price lunch program pursuant to targets established by the board of regents or the board of trustees of the state university of New York, as applicable. Provided, however, if no grounds for terminating a charter are established pursuant to this section other than pursuant to this paragraph, and the charter school demonstrates that it has made extensive efforts to recruit and retain such students, including outreach to parents and families in the surrounding communities, widely publicizing the lottery for such school, and efforts to academically support such students in such charter school, then the charter entity or board of regents may retain such charter.2. Notice of intent to revoke a charter shall be provided to the board of trustees of a charter school at least thirty days prior to the effective date of the proposed revocation. Such notice shall include a statement of reasons for the proposed revocation. The charter school shall be allowed at least thirty days to correct the problems associated with the proposed revocation. Prior to revocation of the charter, a charter school shall be provided an opportunity to be heard, consistent with the requirements of due process. Upon the termination of a charter, the charter school shall proceed with dissolution pursuant to the procedures of the charter and direction of the charter entity and the board of regents.3. In addition to the provisions of subdivision two of this section, the charter entity or the board of regents may place a charter school falling within the provisions of subdivision one of this section on probationary status to allow the implementation of a remedial action plan. The failure of a charter school to comply with the terms and conditions of a remedial action plan may result in summary revocation of the school's charter.4. Any individual or group may bring a complaint to the board of trustees of a charter school alleging a violation of the provisions of this article, the charter, or any other provision of law relating to the management or operation of the charter school. If, after presentation of the complaint to the board of trustees of a charter school, the individual or group determines that such board has not adequately addressed the complaint, they may present that complaint to the charter entity, which shall investigate and respond. If, after presentation of the complaint to the charter entity, the individual or group determines that the charter entity has not adequately addressed the complaint, they may present that complaint to the board of regents, which shall investigate and respond. The charter entity and the board of regents shall have the power and the duty to issue appropriate remedial orders to charter schools under their jurisdiction to effectuate the provisions of this section.5. The regulatory power of the board of regents and the commissioner shall not extend to charter schools except as otherwise specifically provided in this article.
