Knox Middle

Public Grades 6-8

2335^th

SchoolDigger Rank ?

of 2,740 California Middle Schools

Better than 15% of California middle schools

Summary

Knox Middle serves 488 students in grades 6–8 in San Diego, California, among a group of nearby middle schools that includes both San Diego Unified and other districts. Its 2025–2026 proficiency rates were 29% in English language arts (ELA), 15% in math, and 15% in science. The most important finding is that Knox remains below both San Diego Unified and California in all three subjects.

ELA is Knox’s strongest subject relative to nearby schools, while math is its clearest academic concern. Against six nearby San Diego Unified middle schools, Knox’s ELA, math, and science rates were below peer averages of 32%, 19%, and 22%, respectively—shortfalls of 3, 5, and 6 percentage points. Knox ranked fourth of seven schools in ELA and sixth in both math and science. Its ELA rate was 29%, compared with 54% for the district and 49% statewide; math was 15%, versus 46% and 38%; science was 15%, versus 42% and 36%. Attendance is a relative strength: chronic absenteeism was 16% in 2025–2026, below the district’s 17% and state’s 18%; only Roosevelt International Middle had a lower rate among nearby schools with results reported.

Scores have improved overall since 2022–2023: ELA rose 4 percentage points, math 3, and science 4, although ELA fell 3 points from its 2024–2025 peak. Chronic absenteeism dropped 34 points, from 50% in 2021–2022. The gains have not yet lifted Knox’s standing much: SchoolDigger rated it 1 star and placed it at the 15th percentile in 2025–2026, compared with the 4th percentile a decade earlier. In 2024–2025, Knox’s student–teacher ratio was 20.6, and 96% of students were free/reduced lunch eligible. SchoolDigger’s subgroup rankings also differed from the overall result: African American students ranked at the 43rd percentile, and Special Education students at the 41st, down from the 64th percentile the previous year.
