Student head counts by race/ethnicity from federal NCES enrollment data. District, state, and US figures are each group's share of all public school students in that area (US excludes territories). Very small groups may be suppressed in the source, so categories do not always sum exactly to total enrollment.

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.
