Summary:
Zip code 93286 has two elementary schools in Woodlake Unified, serving grades K–5 across two grade spans: Francis J. White Learning Center serves K–2, and Castle Rock Elementary serves grades 3–5. The clearest achievement trend is at Castle Rock: its scores improved in all three subjects from 2024–2025 to 2025–2026, although its latest all-grades results remained below state results.
Castle Rock has the strongest reported grade-level results in grade 3, scoring 4 points above the state in ELA and 2 points above in mathematics. Its grade 4 and 5 mathematics results are the clearest weaker spots: they were 14 and 11 points below the state, respectively; grade 4 and 5 ELA were each about 7 points below. Because only Castle Rock has supplied test scores, the data cannot establish which school has stronger overall achievement. Attendance is a positive measure for both: in 2025–2026, chronic absenteeism was 8% at Castle Rock and 10% at Francis J. White, compared with 18% statewide. Francis J. White had the lower student-teacher ratio, 20.9 students per teacher versus Castle Rock’s 24.5.
Castle Rock’s all-grades scores rose 11 points in ELA, 6 in mathematics and 18 in science from 2024–2025 to 2025–2026, gains larger than the state’s in each subject; its SchoolDigger percentile also climbed from 27 to 47, and its rating increased from 1 star to 2. That improvement followed a drop from the 34th percentile in 2023–2024 to the 27th in 2024–2025. As context, in 2024–2025, 93% of Francis J. White students and 92% of Castle Rock students were reported as free/reduced lunch eligible. These figures describe the schools’ context, not a reason for their results.
