Academically, Knox Middle's performance, as measured by Smarter Balanced Assessments and CAST Science tests, is significantly lower than the district and state averages across all grade levels and subject areas. For example, in 2023-2024, only 26.59% of Knox Middle students were proficient or better in English Language Arts/Literacy, compared to 54.22% in the district and 47.04% statewide.

When comparing Knox Middle to other nearby schools in the San Diego Unified School District, such as Wilson Middle, Mann Middle, and Bell Middle, it becomes clear that Knox Middle is performing significantly worse across various metrics, including academic achievement, chronic absenteeism, and student group performance. These factors, along with the high rates of students eligible for free or reduced-price lunch at Knox Middle, ranging from 91.53% to 95.12%, may be contributing to the school's relatively poor academic performance. However, the data also suggests that with the right strategies and resources, there is an opportunity for Knox Middle to make significant gains in student achievement and overall school quality.

As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
