Summary

Cortez Elementary is a K–8 school in Pomona, California, serving 607 students in Pomona Unified. In 2025–2026, it had the highest all-grades results among the 11 listed nearby schools in English language arts (ELA), math, and science. Its clearest standout is science: Cortez led nearby schools and was 8 points above the state.

Compared with the other 10 nearby schools, Cortez’s results were substantially higher: 45% in ELA, 31% in math, and 44% in science, versus nearby-school averages of 31%, 21%, and 19%. It also exceeded district results by 7 points in ELA, 6 in math, and 21 in science. Statewide, however, Cortez was 4 points below in ELA and 8 below in math, while science was 8 points above. Grade results vary: sixth grade was strong, with 60% in ELA and 47% in math, while fourth grade was a weak spot at 27% in ELA and 18% in math—18 and 25 points below state results, respectively.

Results over time show a striking science gain but less progress elsewhere: science rose 15 points from 2022–2023 to 2025–2026, ELA changed little, and math fell 2 points in the latest year after earlier gains. SchoolDigger gives Cortez a 53rd-percentile statewide ranking and 3 stars in 2025–2026, ahead of the next-nearest listed schools, but that percentile is 13 points below its 2021–2022 level. Cortez’s 2024–2025 student-teacher ratio was 24.7, the highest among nearby schools; 92% of students were reported as free/reduced lunch eligible that year. One notable group result is the SchoolDigger ranking for how well Cortez serves English Language Learner Students: their percentile fell from 92 in 2022–2023 to 33 in 2023–2024, compared with the school’s overall 52nd percentile that year. Chronic absenteeism also improved, dropping from 25% in 2021–2022 to 15% in 2025–2026, below both district and state rates.
