BeatsExpectations
Not computed for this schoolBeatsExpectations 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.
