Summary

K-8 STEM Academy at Red Mountain Ranch in Mesa, Arizona, serves 473 students from prekindergarten through grade 8, with several other schools nearby. Its latest all-grades results are above state and district averages, but closer to the middle among nearby schools. The clearest concern is fifth-grade science: the score fell to 37% in 2024–25 and was well below the nearby-school average.

Overall, the school is stronger against state and district benchmarks than against local peers: ELA proficiency was 53%, 12 points above the state and 14 above the Mesa Unified District; math was 46%, 13 points above the state and 15 above the district. Compared with nearby schools, it was about 1 point above the peer ELA average and 2 points below the math average. Same-grade comparisons show more variation: grade 3 ELA was about 4 points above its nearby average, while grades 5 and 6 math were each about 14 points below their nearby averages. Most nearby schools serve only through grade 6, so all-grades comparisons do not cover identical grade spans.

Fifth-grade science rose from 45% in 2022–23 to 52% in 2023–24, then dropped to 37% in 2024–25; that is an 8-point decline across the period and 3 points above the state rate. SchoolDigger ranks the school 288th of 900, at the 68th percentile with 3 stars; its percentile has fallen from 79 in 2022–23. SchoolDigger’s statewide measure of how well the school serves White students was at the 36th percentile, compared with 68th overall. Its measure for Male Students fell from the 73rd to the 57th percentile between 2024–25 and 2025–26. The 2024–25 student-teacher ratio was 15.7, below the nearby average of 16.4; the reported free/reduced-lunch rate was 25% in 2022–23, with no nearby comparison available.

Saturday, April 6, 2019

I went here before and the teachers are so rude and they do not teach you. I was way to advanced for this school which is why my teacher insisted I apply to the Mesa Academy for Advanced Studies. The students do not respect each other at Red Mountain Ranch Elementary School and it makes for an overall not successful learning environment for all. Close Quote
