What stands out at San Diego Mission Academy

San Diego Mission Academy is a higher-need, mid-sized charter combined-grade school in San Diego, California, enrolling 289 students.

Class loads run heavy: 32.1:1 is larger than about 97% of California schools and 49% above the 21.5:1 state mean, so each teacher carries more students than is typical.

Its free-meal eligibility rate of 55.6% lands close to the California typical range, neither a high- nor low-need campus by this measure.

Enrollment of 289 puts it in the smaller third of California schools by headcount.

Its Resource Investment Index lands in the lower third of 9,998 scored California schools.

Among 927 similarly sized, similarly resourced-need California schools statewide, it ranks #761, in the lower tier once campus size and economic need are matched.

Its student body is led by Hispanic or Latino (49%) and White (26%), more mixed than most schools in the state (diversity index 67/100).

Counselor coverage runs a bit thin, about 289 students per counselor, somewhat past the ASCA-recommended 250:1 benchmark.

Chronic absenteeism is elevated: 52.6% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).

Among San Diego's public schools, it stands alongside The O'farrell Charter (1,862 students): San Diego Mission Academy is smaller than that campus by headcount and runs heavier classes (32.1:1 vs 20.7:1).

San Diego Mission Academy District is a single-school charter district, so San Diego Mission Academy operates independently rather than alongside district-mates.
