State assessment results for this school reflect a specialized student population. The figures above are the school's own reported scores; they are not directly comparable to state averages or to general-enrollment schools, so the usual state-average comparison line is suppressed here.

BeatsExpectations

Not computed for this school
BeatsExpectations is not computed for specialized-population schools (schools for the deaf or blind, therapeutic and behavioral-health placements, juvenile-justice and alternative-education settings, and similar). State ELA/Math proficiency rates are not a comparable metric for these populations, so a demographically-adjusted residual against general-enrollment peers would be misleading.
