Best Public Schools in Zip Code 95457

Schools in ZIP code 95457 include five schools—two elementary schools, two high schools and one alternative school—with 1,927 students in all, from 15 at Highlands Academy to 966 at Lower Lake High. The schools are part of the Konocti Unified area. In 2025–26, every school’s reported all-grades ELA and math proficiency was below the state, and every reported science result was below it too. The most important overall finding is that even the strongest school result in each subject fell short of the state level.

Lower Lake High stood out in ELA and science, with 30% and 17% proficient, respectively; these were about 17 and 9 percentage points above the other reported schools’ averages. Lower Lake Elementary led math at 12%, about 9 points above the other schools’ average. At the lower end, Highlands Academy had the lowest ELA result, 5%, and tied with Carle (William C.) High (Continuation) at 0% in math. Carle also had the lowest reported science result, 4%; Highlands’ science result was not reported.

Group averages edged up from 2024–25 to 2025–26: ELA rose about 1 percentage point to 17%, math about 1 point to 5%, and science about 2 points to 10% among the four schools with results in both years. Science’s increase trailed the state’s, while ELA and math moved slightly closer to state results. SchoolDigger ranked Lower Lake High at the 24th percentile with one star, ahead of Lower Lake Elementary at the 5th percentile and Carle at the 3rd. Other measures add context: Lower Lake High had a 94% graduation rate, above the state’s 88%, but chronic absenteeism was 40%, versus 18% statewide. All five schools reported free/reduced lunch eligibility for 2024–25, ranging from 72% to 93%; this measure does not sort the schools into a simple performance ranking. Schools serve different grade spans, so all-grades comparisons are not perfectly like-for-like.
