Better than 22% of Arizona elementary schools

Summary

William C Jack School is a Glendale PK–8 school serving 811 students in the Glendale Elementary District. SchoolDigger gives it one star and a statewide ranking at the 22nd percentile for 2025–2026; the district ranks at the 16th percentile. The clearest takeaway from the school’s all-grades test results is that ELA is its stronger subject, while math is its main area of concern.

ELA proficiency was 34%, above the district’s 27% but below Arizona’s 41%; it was second-highest among nearby schools with reported results, behind Discovery School at 46%. The nearby-school average was 28%. Math proficiency was 20%, below the district’s 23%, the state’s 33%, and the nearby average of 23%. It tied with Bicentennial South School and was below several nearby schools, including Discovery at 42%. Grade results show important differences: eighth-grade ELA was 53%, higher than the district’s 29% and state’s 39%, and the highest among nearby schools with reported results. Third-grade ELA was 18%, below the district, state, and every nearby school with a reported result.

SchoolDigger’s overall percentile ranking rose from a low of 7 in 2023–2024 to 22 in 2025–2026, though it remains in the lower part of the statewide distribution. Fifth-grade science proficiency also rose overall, from 19% in 2022–2023 to 22% in 2024–2025, including a 10-point increase in the latest year; the latest result was above the district’s 16% but below the state’s 34%. The student–teacher ratio is 20.0, close to the nearby average of 20.6; Discovery School has the same ratio but higher all-grades ELA and math results. The school’s reported free/reduced-lunch rate was 87% in 2022–2023. SchoolDigger’s ranking for how well the school serves students from low socioeconomic status rose from the 15th percentile in 2023–2024 to the 33rd in 2025–2026, above the school’s overall 22nd-percentile ranking.
