Summary:
Zip code 85014 has five high schools, with enrollments ranging from 26 to 1,837; four serve grades 9–12, while The Learning Institute serves grades 7–12. Only North High School and Madison Highland Prep have reportable school-level results for the main current test comparisons. The most important finding is that these two schools show sharply different academic profiles, rather than a consistent pattern across the area.
Madison Highland Prep stands out among schools with reported results: in 2025–26, 50% of students were proficient in ELA and 53% in math, compared with 15% and 9% at North High School. Madison’s leads were 35 percentage points in ELA and 44 in math. In 11th-grade science in 2024–25, Madison was also ahead, 41% to North’s 8%, a 33-point gap. Madison was above the state in each of these measures; North was below it. SchoolDigger ranks Madison 66th of 256 schools, at the 74th percentile with four stars, and North 232nd, at the 9th percentile with zero stars.
SchoolDigger’s ranking histories show different paths, but do not establish changes in test scores: Madison’s percentile rose from 69 in 2023–24 to 74 in 2025–26, while North went from 9 to 3 and back to 9. Earlier records show The Learning Institute moving from 17 to 14 to 18 between 2020–21 and 2022–23, and Pinnacle High School - Casa Grande rising from 18 in 2011–12 to 27 in 2020–21. Madison’s reported student–teacher ratio is higher than North’s—23.1 versus 18.8—even though its test results are stronger, so the ratio alone does not explain the difference. North’s 2024–25 graduation rate was 72%, below the state’s 80%. Only North and Madison have usable results for the current test comparisons, so the scores do not support ranking all five schools academically.
