Summary:
ZIP code 93458 has 10 schools in the Santa Maria-Bonita district: eight elementary schools serving kindergarten through grade 6 and two junior highs serving grades 7–8, with no high schools. In 2025–2026, results varied considerably among schools, but no school group’s average matched its grade-level state results. Across the listed grade-and-subject comparisons, school averages were 19 to 26 percentage points below state averages—the clearest area-wide finding.
Ontiveros (Juan Pacifico) Elementary stands out among elementary schools, leading in ELA at 40%, math at 31% and science at 21%. Those results were 11 points above the next-highest school in ELA, 5 points in math and 2 points in science. At the other end, Bonita Elementary had the lowest ELA and math results, at 11% each; Adam (William Laird) Elementary had the lowest science result, at 9%. Among junior highs, Kunst (Tommie) Junior High led El Camino Junior High by 13 points in ELA, 5 in math and 7 in science.
Recent results were mixed: across the 10 schools, the unweighted average was essentially flat in ELA from 2024–2025 to 2025–2026, fell 2 points in math and rose 2 points in science. SchoolDigger ranked Ontiveros highest among the elementary schools, at the 40th percentile, followed by Sanchez (David J.) Elementary at the 24th; Ontiveros had been at the 51st percentile two years earlier. Among junior highs, Kunst ranked at the 23rd percentile and El Camino at the 7th. Similar enrollment and student-teacher ratios do not guarantee similar results: Ontiveros and Adam enroll 869 and 874 students, with ratios of 24.8 and 24.6, yet Ontiveros scored higher in all three subjects. Their free/reduced lunch eligible measures were 94% and 97%, respectively, for school year 2024–2025; these figures provide context, not an explanation for the score difference.
