Summary:
Schools in zip code 95453 include six schools: one elementary, one middle, three high schools and one alternative school. Five report 2025–26 English language arts (ELA) and math results, four report science results, and Lloyd Hance Community has no test results in the supplied data. The school averages are 33% in ELA, 14% in math and 24% in science, compared with state rates of 49%, 38% and 36%, respectively. The clearest area-wide concern is math, where the average is 24 percentage points below the state rate.
Which school stands out depends on the subject. Clear Lake High leads ELA at 43%, while Natural High leads math at 21%; Lakeport Alternative (Home School) leads science at 33%. The lowest results are 19% ELA at Lakeport Elementary, 10% math at Clear Lake and 17% science at Clear Lake. Clear Lake and Natural High are nearly tied in ELA—43.1% and 42.9%—but Natural is ahead by 11 points in math and science.
Recent progress is mixed: the five-school ELA average rose 9 points and the four-school science average rose 8, while the math average fell 6 points from 2024–25 to 2025–26. Lakeport Alternative improved in all three subjects and had 18.1% chronic absenteeism, just below the 18.3% state rate; Natural High’s rate was 67.6%. SchoolDigger ranks Clear Lake at the 30th percentile and Natural at the 43rd in 2025–26, while Lakeport Elementary is at the 4th and Terrace Middle at the 9th. As context, 2024–25 free/reduced lunch eligible shares were 84% at Natural and 77% at Clear Lake; Natural also has 25 students and a 24.5 student-teacher ratio, compared with Clear Lake’s 335 students and 16.0 ratio. These measures provide context, not an explanation for test results.
