Summary:
ZIP code 92346 has 13 schools—10 elementary, two middle and one high—serving students from elementary through high school in Redlands Unified and San Bernardino City Unified. In 2025–26, the schools’ unweighted average proficiency was 38% in ELA, 27% in math and 27% in science, compared with state results of 49%, 38% and 36%. The central finding is that all three area averages were below the state, while individual schools’ results varied widely—by 38 to 50 percentage points from lowest to highest, depending on the subject.
Highland Grove Elementary led ELA at 57%, 7 points above the state, and also beat the state in math (42% versus 38%) and science (44% versus 36%). Cram Elementary led math at 51% and science at 48%, both well above the state; it also scored 55% in ELA. SchoolDigger gives Cram four stars and ranks it in the 72nd percentile; Highland Grove is in the 67th percentile. Arroyo Verde Elementary also exceeded the state in all three subjects, with 52% in ELA, 42% in math and 39% in science. At the other end, San Andreas High had the lowest results in each subject: 7% ELA, 2% math and 10% science, despite a reported graduation rate of 92%, above the state’s 88%.
Average results improved from 2024–25 to 2025–26 by 2 points in ELA, 3 in math and 4 in science—larger gains than the state’s increases in each subject—and the gaps with the state narrowed. Highland Pacific Elementary improved most among these schools, gaining 15 points in ELA, 21 in math and 26 in science, although it remains below the state in ELA and math. Context figures vary too: for 2024–25, free/reduced lunch eligible students made up 42% at Cram, 65% at Highland Grove, 59% at Arroyo Verde and 97% at Lankershim Elementary; these are observations, not explanations for scores. Grade-level results can also help distinguish schools: fifth-grade ELA was 63% at Arroyo Verde, compared with 49% statewide.
