Summary:
Schools in ZIP code 94553 include 10 schools—five elementary schools, one middle school, three high schools and one alternative school—serving students from elementary through high school. Results vary widely: across the nine schools with reported scores, proficiency ranges from 10% to 71% in English language arts (ELA), from 0% to 61% in math, and from 5% to 57% in science. The clearest overall finding is that Morello Park Elementary is the strongest all-around elementary school, while scores differ substantially among schools.
Morello Park leads the elementary schools in all three subjects, scoring 65% in ELA, 61% in math and 57% in science—16, 23 and 21 percentage points above state rates. John Swett Elementary is the next strongest elementary school, and Morello’s lead is 5 points in ELA, 8 in math and 7 in science. Briones (Alternative) has the highest reported ELA score overall at 71%, but its math score is 33%. At the other end, Vicente Martinez High has the lowest result in each subject: 10% in ELA, 0% in math and 5% in science. By comparison, Alhambra Senior High scores 63% in ELA and 48% in science, though its math result is below the state rate.
Recent gains are uneven. From 2024–2025 to 2025–2026, Las Juntas Elementary improved by 11 points in ELA, 5 in math and 18 in science, yet remains below state rates in all three. Briones had especially large gains, including 46 points in ELA; excluding it, the other eight schools’ average changes trailed state improvement in all three subjects. SchoolDigger rankings put Morello at the 84th percentile among California elementary schools and Las Juntas at the 49th. Contextual measures do not sort schools neatly: in 2024–2025, free/reduced lunch eligible figures were 20% at Morello and 49% at Las Juntas; student-teacher ratios were 26.5 at Hidden Valley Elementary and 19.1 at Las Juntas. Mt. McKinley’s test scores are suppressed, so no score comparison is available.
