Schools in Zip Code 92688

ZIP code 92688 has 10 schools—six elementary, three middle and one high school—across Capistrano Unified and Saddleback Valley Unified. Overall, the schools’ 2025–26 average proficiency was above California’s in English language arts (ELA), math and science: 70% versus 49% in ELA, 65% versus 38% in math, and 62% versus 36% in science. But results differ considerably from school to school: the gaps between the highest and lowest results were 44 points in ELA, 39 in math and 34 in science. The most important takeaway is that the area’s strong averages do not reflect every school, especially Cielo Vista Elementary, which was below the state in ELA and about level with it in math.

Standouts vary by subject and grade. Tesoro High led All Grades ELA at 85%; among elementary schools, Las Flores Elementary led ELA at 80% and math at 78%. Arroyo Vista Middle led science at 76%, while Cielo Vista had the lowest reported All Grades results: 41% in ELA, 38% in math and 42% in science. Its ELA result was 8 points below California’s 49%; its math result was essentially level with the state’s 38%. In grade-level results, leadership shifts: Trabuco Mesa Elementary led grade 3 ELA and math, and Tijeras Creek Elementary led grade 5 ELA, math and science.

Recent trends are mixed, with science improving most on average: from 2024–25 to 2025–26, the 10-school averages changed by −1 point in ELA, +1 in math and +3 in science. Tijeras Creek had a particularly large science rise of 21 points. SchoolDigger’s statewide rankings put Tesoro at the 97th percentile and Tijeras Creek and Las Flores Elementary at the 94th; Cielo Vista ranked at the 52nd percentile. The reported free/reduced lunch eligible measure for 2024–25 was 65% at Cielo Vista, 37% at Trabuco Mesa and 22% at Tijeras Creek; these figures offer context, not an explanation for results. Among these elementary schools, reported student-teacher ratios were 23.4 at Cielo Vista and 25.2 at Las Flores, despite their very different scores.
