Summary:
ZIP code 60645 has five elementary schools serving through grade 8: four offer pre-K through grade 8, while Decatur Classical Elementary School begins in kindergarten. In 2025–26, results varied sharply: the five-school unweighted averages were 58% in ELA and 48% in math, but without Decatur the averages were 48% and 36%, both below the state figures of 56% and 40%. The most important finding is that Decatur’s unusually high results make the area-wide averages look stronger than results at the other four schools.
Decatur Classical was the clear leader, with 99% all-grade ELA and 96% math, plus 97% in grade 5 science and 93% in grade 8 science. Its ELA score led the next-highest school by 43 points, and its math score led by 55 points. At the other end, Mosaic School of Fine Arts had the lowest ELA (32%) and math (25%); those scores were 23 and 13 points below the next-lowest school, West Ridge Elementary School. Among the other schools, Rogers Elementary School had the highest all-grade ELA at 56%. Grade-level strengths add nuance: West Ridge scored 59% in grade 3 math, 10 points above the state, while Armstrong G Elementary International Studies scored 68% in grade 8 ELA, 5 points above the state. SchoolDigger ranked Decatur 4th of 1,737 schools (100th percentile) and Mosaic 1,513th (13th percentile) in 2025–26.
Two-year score changes were mixed: West Ridge’s all-grade ELA rose 10 points and Decatur’s rose 3, while ELA fell at the other three schools by 3 to 6 points. In math, West Ridge and Mosaic gained 5 and 4 points, while Armstrong and Rogers fell 3 and 2; Decatur was essentially unchanged. SchoolDigger percentiles also declined over three ranking years for Armstrong, Rogers, Mosaic and West Ridge, while Decatur stayed at the 100th percentile. As context, the reported measure was free/reduced lunch eligible, 2024–25: Decatur was at 12%, Mosaic at 89%, and Armstrong and West Ridge were similar at 84.3% and 84.8%. Chronic absenteeism was 7% at Decatur and 27%–39% at the other schools; these differences are observations, not explanations of test results.
