Summary:
Arvin, California, has six schools serving a calculated 5,685 students: four elementary schools, one middle school and one high school. In 2025–26, the schools’ average proficiency was about 31% in English language arts (ELA), 17% in mathematics and 16% in science, compared with California averages of 49%, 38% and 36%. The most important finding is that average proficiency trails the state in all three subjects, with the largest gap in mathematics—about 21 percentage points.
Different schools lead in different subjects. Arvin High had the highest all-grades ELA result, 47%, and science result, 29%; those were about 12 points above the next-highest ELA result at Haven Drive Middle and 6 points above the next-highest science result at Sierra Vista Elementary. Sierra Vista led mathematics at 26%, about 1 point above El Camino Real Elementary. At the other end, Bear Mountain Elementary had the lowest ELA result at 20%, Arvin High the lowest mathematics result at 10%, and Haven Drive the lowest science result at 11%. Grade-by-grade results add nuance: El Camino’s grade-six ELA proficiency was 53%, above the state’s 48% for that grade.
Recent results show no broad area-wide improvement: from 2024–25 to 2025–26, the six-school average was essentially unchanged in ELA and fell about 2 points in both mathematics and science, while state results rose in each subject. There are school-specific exceptions, including gains at Sierra Vista in all three subjects. SchoolDigger’s 2025–26 statewide rankings put Arvin High at the 39th percentile, compared with the 5th percentile for Bear Mountain and 4th for Di Giorgio Elementary; Sierra Vista’s ranking improved from the 15th to the 24th percentile over two years, while Haven Drive’s fell from the 40th to the 21st. As context, five schools reported free/reduced lunch eligible figures for 2024–25, ranging from 89% at El Camino to 97% at Arvin High; Di Giorgio reported 62% directly certified for free meals in 2024–25, a different measure. Ratios also vary: El Camino and Sierra Vista each had 22.6 students per teacher, compared with 20.2 at Bear Mountain. These measures do not by themselves explain differences in results.
