Summary

Mountainside Middle School serves 518 students in grades 6–8 in Scottsdale, within the Scottsdale Unified District. In 2025–26, 62% of students were proficient in English language arts (ELA) and 52% in math, both above Arizona’s rates of 41% and 33%. The clearest takeaway is that Mountainside is well above the state in both subjects, while math is its more notable relative weakness compared with its district and nearby schools.

ELA is a strength: Mountainside’s 62% rate was 1 percentage point above the district and matched the 62% average at nearby Cocopah Middle School, Desert Canyon Middle School and Mohave Middle School. Its eighth-grade ELA rate was 60%, second only to Cocopah’s 66% among nearby schools with a reported score for that grade. Math was 52%, 4 points below the district and about 4 points below those three schools’ average. Eighth-grade science was 45%—15 points above the state, but 2 below the district and about 5 below those nearby Scottsdale Unified schools’ average. The nearby schools do not all serve the same grade spans, so same-grade comparisons are more direct.

Results vary by subject and year: ELA ranged from 60% to 63% across grades 6–8, while math rose from 47% in grade 6 to 55% in grade 8. Science moved from 36% in 2022–23 to 48% in 2023–24 and 45% in 2024–25, remaining above the state each year. SchoolDigger ranked Mountainside in the 84th percentile statewide, 85th of 536 schools, with 4 stars in 2025–26; its percentile was 94 in 2015–16 and 80 in 2024–25. The student–teacher ratio was 16.1 in 2024–25, and the reported free/reduced-lunch rate was 11% in 2022–23; comparable nearby rates were not supplied. SchoolDigger’s effectiveness ranking for White students was at the 65th percentile in 2025–26, compared with the school’s overall 84th percentile. Its ranking for multi-racial students shifted from the 92nd percentile in 2020–21 to the 20th in 2022–23.
