Summary:
ZIP code 66414 has one middle school, Carbondale Attendance Center, serving grades 4–8 and 370 students in the Santa Fe Trail district. With no other middle schools in the ZIP code, the most useful comparison is with state results and between subjects and grades. Overall, Carbondale’s results are close to the state average, but science is ahead while ELA is behind: in 2025–26, science proficiency was 42% versus 38% statewide, ELA was 42% versus 46%, and math was 40% versus 41%.
Within Carbondale, grade 5 math stands out as a strength, while grade 5 ELA is the clearest concern. Grade 5 math proficiency was 52%, 7 percentage points above the state’s 45%; grade 5 ELA was 38%, 13 points below the state’s 51%. Grade 5 science was also below the state rate, at 37% versus 46%. Grade 8 showed a different pattern: ELA was 47% versus 42% statewide and science was 47% versus 39%, while math was 31% versus 40%. These differences show why the school’s overall rates do not tell the whole story for every grade or subject.

From 2024–25 to 2025–26, math rose 9 percentage points at Carbondale, compared with 2 points statewide; science rose 6 points as the state rate fell 3 points.
