Summary:
The 15 schools in Walnut Valley Unified include nine elementary schools, three middle schools and three high schools, including a continuation school. SchoolDigger rates the district five stars and ranks it 54th of 968 California districts, in the 94th percentile. Across the 14 schools with reported scores, unweighted averages were 74% in English language arts (ELA), 72% in math and 63% in science, compared with state scores of 49%, 38% and 36%. Scores for Ron Hockwalt Academies are state-suppressed, and the school averages are not student-weighted. The clearest overall finding is that every school with reported scores is above the state in all three subjects.
Elementary results show the widest differences: Maple Hill leads ELA at 82%, 25 points above Vejar at 58%; Leonard G. Westhoff leads math at 81%, 22 points above Vejar at 59%; and Quail Summit leads science at 76%, 25 points above Collegewood at 51%. Among middle schools, Chaparral leads ELA and math, while South Pointe leads science; Suzanne is lowest in all three. The two traditional high schools split the lead: Walnut High is ahead in ELA and science, while Diamond Bar High leads math.
Year-to-year changes are mixed: the average fell by 1 point in ELA and 1 point in math, while science rose by 1 point. Even so, the average school lead over the state narrowed in all three subjects: from 26 to 24 points in ELA, 35 to 33 in math, and 29 to 27 in science. School results do not line up simply with student-teacher ratios or the low-income measure. For elementary schools, the reported measure is free/reduced lunch eligible (FRL), 2024–2025: Westhoff’s share was 20%, Vejar’s 32%, and Maple Hill’s 27%. Westhoff’s ratio is 26.4 students per teacher, while Vejar’s is 23.0; these figures provide context, not an explanation for test results.
