Profile interpretation

How to read Glendale Union Online's results

Statewide standing

Glendale Union Online ranks #227 among 270 eligible Arizona public high schools in the 2025 achievement ranking. Its score is -0.97, corresponding to a statewide percentile of 16 among eligible schools.

Published subject results

The three-year reportable passing percentages are ACT English Language Arts 18%, ACT Mathematics 10%, and AzSCI Science 12%. The ranking uses available proficiency bands and the published suppression fallbacks, so passing percentages provide context but are not the score by themselves.

Enrollment and tested counts

The reported three-year tested count is 307. NCES enrollment is 285 in the NCES 2024-25 snapshot. Because these figures cover different periods and populations, tested divided by enrollment is not a participation rate. The count covering scoreable years is 304; this is the separate count used for eligibility when it is available.

School and admissions context

Glendale Union Online is classified as a online public school in GLENDALE, Maricopa County. The profile uses an online instructional context label so families can account for meaningful differences in enrollment and instructional models when comparing schools.

Admissions evidence

Not yet verified

Admission requirements have not yet been verified. Normal is a classification, not a guarantee of unrestricted admission.

A normal-context label is not proof of unrestricted entry. Policies, grade openings and capacity can change. Confirm the process directly with the school.

Annual assessment results

Reported proficiency for different yearly cohorts is not individual student growth or a measure of teaching effectiveness. Missing years and suppressed cells remain gaps.

Four-year and five-year figures can refer to different graduating cohorts. ADE enrollment is an October snapshot across all campus grades, separate from the NCES enrollment above. Protected cells remain unavailable; a reported bound is not an exact rate. These context measures do not change the Achievement score.

Official A-F grades and open-enrollment participation are not yet verified in this export. Historical participation would not establish current seat availability.
