There is no within-ZIP-code top or bottom school to compare: John Knight is the only school listed, not a peer-group leader. In 2025–2026, its ELA proficiency was 34% versus 49% statewide, a 15-point gap; math was 22% versus 38%, a 16-point gap; and science was 24% versus 36%, a 12-point gap. Science was therefore closest to the state rate, while math had the largest shortfall. Within the school, 8th-grade math was a relative bright spot: 28% were proficient, compared with 19% in both 6th and 7th grades, although the 8th-grade result remained 8 points below the matching state rate. ELA was highest in 7th grade at 36%, with a 5-point spread between the highest and lowest grades.
Reported proficiency rose in all three subjects from 2024–2025 to 2025–2026, most in ELA: John Knight gained 7 points in ELA, 1 point in math, and 4 points in science. The state gaps narrowed by 7 points in ELA and 1 point in science, but widened by less than 1 point in math. SchoolDigger ranked the school in the 29th percentile with one star in 2025–2026, up from the 26th percentile and one star the prior year, but below its 37th-percentile, two-star rating in 2023–2024. As context, 69% of students were free/reduced lunch eligible in 2024–2025; this is a separate school measure, not a measure of meal availability.
