Summary:
The two middle schools in Flagstaff Unified District serve grades 6–8 in the Flagstaff area. In 2025–26, both schools’ all-grades AASA proficiency rates were below district and state results in ELA and math: the two-school averages were 29% in ELA, compared with 34% for the district and 41% statewide, and 19% in math, compared with 26% and 33%. The most important distinction is that Mount Elden Middle School leads the local comparison, though neither school’s overall results reach state proficiency.
Mount Elden Middle School stands out in both AASA subjects, while Sinagua Middle School has the lower all-grades results: Mount Elden scored 32% in ELA and 23% in math, versus Sinagua’s 26% and 15%. That puts Mount Elden 6 percentage points ahead in ELA and 8 points ahead in math. Some grade-level results are closer to the state: Mount Elden’s eighth-grade ELA score was 38% versus 39% statewide, and its seventh-grade math score was 26% versus 27%. Science is the exception to the AASA pattern: in eighth grade in 2024–25, Sinagua scored 24%, compared with Mount Elden’s 22%; both were below the state’s 30%.
SchoolDigger’s statewide percentile rankings improved for Mount Elden but not Sinagua between 2023–24 and 2025–26: Mount Elden rose from the 16th to the 32nd percentile, while Sinagua slipped from the 16th to the 15th. Mount Elden is also smaller, with 678 students and a student–teacher ratio of 14.5, compared with Sinagua’s 1,013 students and ratio of 16.5; these are useful differences to consider, but do not explain the score gap. Test-score trends cannot be determined from the available results, which cover one year for ELA and math and a different year for science.
