Best Public Schools in Pomona, CA

Pomona has 35 schools—21 elementary, three middle, nine high and two alternative—serving students from elementary through high school, mostly in Pomona Unified. In 2025–2026, the average reported proficiency was about 38% in ELA, 23% in math and 22% in science, compared with 49%, 38% and 36% statewide. The clearest finding for families is that these averages hide very large differences from one school to another.

International Polytechnic High led all schools in all three subjects, with 89% proficiency in ELA, 60% in math and 58% in science; Park West High (Continuation) had the lowest reported results, at 8%, 2% and 6%. The gap between those schools was 81 percentage points in ELA, 58 in math and 51 in science. SchoolDigger ranks International Polytechnic at the 94th statewide percentile and gives it five stars. Among Pomona Unified schools, Ranch Hills Elementary stands out with 57% ELA and 47% math proficiency; its 36% science result is close to the state’s 36%. SchoolDigger ranks it at the 68th percentile. Cortez Elementary also stands out in science, with 44% compared with 36% statewide.

Across the same 34 schools, average proficiency rose from 37% to 38% in ELA, 22% to 23% in math and 19% to 22% in science between 2024–2025 and 2025–2026; only the ELA gap with the state narrowed, while the math and science gaps widened. SchoolDigger’s rankings also show shifting fortunes: Garey High moved from the 43rd to the 70th percentile. Similar reported free/reduced lunch eligible shares in 2024–2025 do not mean similar results: Cortez, Pomona High and Ganesha High were each around 92% eligible, yet their subject results differed. These are school-level all-grade figures across schools with different grade spans, so grade-specific results can offer a more direct comparison.
