Poston Butte High School's performance has been inconsistent, with fluctuations in its statewide ranking and SchoolDigger rating over the years. The school's academic proficiency rates in subjects like Science, English Language Arts, and Mathematics are generally below the state averages, though comparable to nearby schools like Combs High School and San Tan Foothills High School. The school's graduation rate has also varied, ranging from 77.5% to 93.3% in recent years.

One notable finding is the growing percentage of students at Poston Butte High School who are eligible for free or reduced-price lunch, increasing from 15.62% in 2021-2022 to 44.94% in 2022-2023. This suggests a rising population of students from low-socioeconomic backgrounds, which may contribute to the school's academic challenges. In contrast, Queen Creek High School, which is part of a different district, has a higher ranking and rating of 3-4 stars from SchoolDigger.

Open Quote 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

Open 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
