Summary:
ZIP code 92831 has seven schools: three elementary schools serving K–6, one junior high, and three high schools, including alternative and continuation programs. Their 2025–2026 results range widely, with Troy High leading and La Vista High (Continuation) at the bottom in all three reported all-grade subjects. The most important takeaway is that school results in this ZIP code are highly uneven, not uniformly strong or weak.
Troy High stands out at the top, with 86% proficiency in ELA, 76% in math and 75% in science—75, 67 and 69 percentage points above La Vista High (Continuation), respectively. Among the K–6 schools, Acacia Elementary leads with 76% ELA, 73% math and 59% science; Commonwealth Elementary has the lowest elementary results, at 34%, 29% and 22%. La Sierra High (Alternative) is a notable exception to the low results at the alternative and continuation schools: its 67% science result is second highest, while its current ELA and math scores are suppressed. SchoolDigger’s 2025–2026 statewide rankings place Troy at the 98th percentile and Acacia at the 92nd; La Vista is at the 14th.
Recent changes are mixed: Ladera Vista Junior High School of the Arts gained 2 points in ELA, 3 in math and 7 in science, while Acacia fell 4, 1 and 7 points, respectively. Commonwealth’s ELA was unchanged, but math rose 4 points and science 10; La Sierra’s reported science result jumped 31 points. Among the elementary schools, Acacia also has the highest student–teacher ratio, at 31.4, and the lowest free/reduced lunch eligible share, 33% in 2024–2025; Commonwealth’s figures are 22.3 and 77%, while Raymond’s are 28.4 and 57%. These are contextual differences, not explanations for results. All-grade comparisons span different grade ranges, so treat them as broad comparisons.
