Serrano leads in every subject with a reportable 2025–26 result: 50% in ELA, 19% in math and 32% in science.

Chaparral is lower in each subject, at 21% in ELA, 2% in math and 10% in science; Eagle Summit has 6% in both ELA and math, and its science result is suppressed. Serrano’s ELA advantage is 29 points over Chaparral and 43 points over Eagle Summit; its math lead over Chaparral is 17 points.

Average proficiency improved from 2024–25 to 2025–26: the three-school ELA average rose 6 points and the math average rose 2 points, though both remain well below state results. SchoolDigger ranks Serrano at the 48th percentile and Chaparral at the 15th percentile in California; Eagle Summit’s ranking is from a much earlier year and is not comparable. In 2024–25, student-teacher ratios were 21.7 at Serrano, 14.1 at Chaparral and 7.9 at Eagle Summit, while free/reduced lunch eligible figures were 58%, 84% and 79%, respectively. These are useful context, not explanations of achievement. Eagle Summit’s wider grade span means its all-grades results are not directly comparable with the two grades 9–12 schools.
