Summary

Knox Middle is a public school serving 488 students in grades 6-8 within the San Diego Unified district, operating in a high-need community where nearly all students qualify for free or reduced-price lunch.

Academically, the school faces significant challenges, with test scores in English, math, and science well below state and district averages, placing it in the bottom quartile of California middle schools. However, it's important to note that this is a common trend among several nearby San Diego Unified schools like Wilson Middle and Mann Middle, which perform similarly. Some schools in neighboring districts, such as Granger Junior High in the Sweetwater Union High district, achieve higher scores despite having much lower per-student funding.

Despite the overall academic struggles, Knox Middle shows notable strengths in supporting specific student groups, with its programs for special education students ranking above average statewide. The school has also made substantial progress in reducing chronic student absenteeism, cutting the rate in half since 2022, though it remains higher than average. This improvement, along with a recent slight uptick in English scores, suggests the school is implementing strategies to address key challenges.
