Summary

Mason Elementary is a K–5 school in San Diego Unified with 538 students, serving families in San Diego alongside 10 nearby K–5 schools in the data. In 2025–2026, 40% of students were proficient in English language arts (ELA), 45% in math and 28% in science. Most importantly, Mason had the lowest ELA result and the second-lowest math and science results among the 11 nearby schools compared.

Math is Mason’s strongest subject: its 45% proficiency was 7 points above California’s 38% and nearly even with San Diego Unified at 46%, although it was 23 points below the nearby-school average of 69%. ELA proficiency was 40%, below the state’s 49% and district’s 54%, and 24 points below the nearby average of 63%. Science was weakest against all three comparisons: Mason’s 28% was below the state’s 36% and district’s 42%, and 30 points below the nearby average of 58%. Attendance is another concern: chronic absenteeism was 20% in 2025–2026, higher than the district’s 17%, the state’s 18%, and every nearby school in the reported range of 4.3%–17.3%.

Results show mixed trends: from 2022–2023 to 2025–2026, math rose 6 points and science rose 4, while ELA fell 6 points. SchoolDigger gives Mason 3 stars and a 53rd-percentile ranking, the second-lowest among the nearby schools; its percentile was 75 in 2018–2019. SchoolDigger’s statewide effectiveness ranking for Special Education Students rose from the 12th percentile in 2024–2025 to the 38th in 2025–2026, still below Mason overall at the 53rd percentile. Mason’s reported free/reduced lunch eligible measure was 71% in 2024–2025; California is a statewide-free-meals state, so this figure does not indicate who receives meals. Its 24.4 student–teacher ratio in 2024–2025 was close to the nearby-school average of 24.3.

What people are saying

by a parent
Thursday, April 12, 2012

My daughter went to Mason until we moved . She loved it especially Mrs. Mercado, she is a wonderful teacher very dedicated to her students. The school encourages parents to volunteer at the school, just helping the teacher out, by cutting or sorting organizing things for the class. I enjoyed doing this and I wanted to show my daughter that school is something important. I was skeptical at first, because the school was rated 3 starts out of 5, but in my opinion the kids, for being just in kindergarten were learning how to read or were able to read by the end of the year was pretty impressive. This is a whole year round school no long summer vacation. They have one month of vacation in Christmas spring and summer. What I think was great that math and reading where link online and you can learn with your child at home. I loved this school and I would go to this school again, if we ever move back here.
