Summary

Poston Butte High School in San Tan Valley, Arizona, serves grades 7–12 and enrolls 1,310 students. Its latest all-grades results show ELA proficiency of 31% and math proficiency of 24%—both above the Florence Unified School District, but below Arizona overall. The school’s most important bright spot is 11th-grade science: its 22% proficiency in 2024–25 was above the state and every nearby school with a reported score.

Poston’s academic picture varies by subject: ELA and math are stronger than district results but trail the state and leading nearby schools. Its all-grades ELA and math rates are 5 and 6 points above the district, respectively, but 10 and 9 points below Arizona. In 11th grade, Poston’s ELA and math results were each 7 points below the state; nearby Queen Creek High School and Crismon High School scored higher in both subjects. Science tells a different story: Poston’s 22% was 3 points above the state and 5 above the district, and topped reported results from San Tan Foothills High School, Queen Creek, and Crismon. Graduation is another strength: Poston’s 92% rate in 2024–25 was 2 points above the district and 12 above the state.

Poston’s SchoolDigger standing has improved, rising from the 26th percentile in 2023–24 to the 39th percentile and 2 stars in 2025–26, though it remains behind nearby Queen Creek and Crismon. Its graduation rate has eased from a recent peak of 95% in 2021–22 to 92%, while its student-teacher ratio of 18.8 is close to the nearby-school average of 19.3. The only reported free/reduced-lunch rate was 45% in 2022–23; nearby rates were not supplied. SchoolDigger’s relative standing for Hispanic students rose from the 13th to the 39th percentile over three years, matching the school’s overall 39th-percentile standing in 2025–26. Its White student ranking was lower, at the 18th percentile.

Black families beware! This school is extremely racist and promotes a bullying culture. When it comes to protecting your child, they will not do it. The higher up admin sweeps incidents under the rug and do not address properly parents concerns! I do not recommend this school. The catch 22 is, out here in San Tan Valley, it is the better of the horrible schools out here. Some of the teachers are great. This is not a premier high school. Please believe all of the bad reviews you have read!!! Close Quote

I attend here, and have been to quite a few schools. This one (and the FUSD's for that matter) has a unique laptop program, and the staff care more about their students then most teachers. The students are also very supportive, I am a new freshmen and have not gotten one comment yet. Close Quote
