Finally, as to credibility, under the substantial evidence test, “[i]n assessing the agency's decision, we show particular deference to credibility determinations and inferences drawn from the facts.” Collamore v. Office of Campaign & Political Fin., 67 Mass. App. Ct. 315, 322 (2006). The low standards chosen by the Legislature with respect to a DCF finding that a § 51A allegation is supported — reasonable cause to believe, with review for substantial evidence — make sense because the determination that an allegation of child abuse and neglect received under § 51A is “supported” is what allows DCF to begin to take steps to protect the child.
Moreover, where, as here, a decision rests in part on an agency's assessment of witnesses, we give "particular deference to credibility determinations and inferences drawn from the facts." Collamore v. Office of Campaign Political Fin., 67 Mass. App. Ct. 315, 322 (2006). See Morris v. Board of Registration in Med., 405 Mass. 103, 111, cert. denied, 493 U.S. 977 (1989).
" G.L.c. 30A, § 1(6). "In assessing the agency's decision, [courts] show particular deference to credibility determinations . . ." Robert v.

Notwithstanding this deferential standard of review, this court concludes that the DCF's decision was not supported by substantial evidence.
