San Luis Middle School

San Luis Middle School in San Luis, Arizona, serves 620 students in grades 6–8 in the Gadsden Elementary District. Its latest results show that performance varies by subject: math compares relatively well with nearby middle schools, while eighth-grade science is the school’s clearest academic weakness.

In 2025–26, all-grades proficiency was 23% in ELA and 18% in math, both below the state (41% and 33%) and district (32% and 31%). Compared with six nearby schools serving grades 6–8, San Luis’s ELA result was below their 27% average, while its math result was above their 15% average. Eighth-grade science proficiency was 11% in 2024–25, below the state’s 30%, the district’s 13%, and all six nearby schools with results, which averaged 17%. Grade-level comparisons also show a mixed picture: eighth-grade ELA was 21%, the lowest among nearby schools with reported results, while seventh-grade math was 17%, above all but one nearby result.

Science proficiency moved from 10% in 2022–23 to 12% and then 11%; over the same period, the gap below the state widened from 17 to 19 percentage points. SchoolDigger places San Luis at the 17th statewide percentile, rank 444 of 536, with 1 star—up from the 14th percentile in 2023–24, but still below the nearby-school average of 24. Its 31:1 student–teacher ratio is the highest among nearby schools, whose average is 21.7:1. The reported free/reduced-lunch rate was 96% in 2022–23, offering context but not explaining academic results. SchoolDigger’s special education student ranking also changed sharply: the group was at the 73rd percentile in 2020–21, compared with the school’s overall 38th percentile, then at the 2nd percentile in 2022–23, when the overall percentile was 25; this points to a notable shift in how the school served that group, not a consistent trend. ELA and math have results for only one year, and nearby lunch-rate figures are unavailable.
