Summary

Sierra High is a public school in Manteca, California, serving 1,670 students in grades 9–12 in the Manteca Unified area. In 2025–26, its proficiency rates were 68% in English language arts, 41% in math and 48% in science—above state and district rates in all three subjects. The clearest takeaway is that Sierra pairs strong results across subjects with a particularly large advantage in English language arts.

Among nearby schools, Sierra ranked second in each tested subject, behind Ripon High. Its English language arts rate was 18 percentage points above the state, 32 above its district and 29 above the nearby-school average. Its science rate led those comparisons by 12, 25 and 28 points, respectively. Math is the relative weak spot: Sierra was just 3 points above the state, though it was 18 points above the district and 25 above the local average. Other outcomes are favorable, too: its 97% graduation rate compares with 95% in the district and 88% statewide.

Math proficiency rose 12 points from 2022–23 to 2025–26, moving from 6 points below the state to 3 points above it; English language arts remained consistently strong, while its state lead stayed roughly level. SchoolDigger gives Sierra four stars and an 80th-percentile statewide ranking (438 of 2,137), with only Ripon High ranked higher among nearby schools. That school ranking contrasts with the district’s 16th-percentile, one-star SchoolDigger ranking. Sierra’s 2024–25 student–teacher ratio was 22.6, the highest among the nearby schools, whose average was 15.6; 56% of its students were free/reduced lunch eligible that year, near the local average of 59%. A notable concern in SchoolDigger’s student-group rankings is special education: its measure of how well Sierra serves special education students placed the school at the 4th percentile in 2025–26, far below its 80th-percentile overall ranking.
