Summary

Delta High is a small school serving 291 students in grades 9–12 in Santa Maria, within the Santa Maria Joint Union High district. Its 2025–26 graduation rate was 97%, but only 17% of students were proficient in English language arts (ELA), 0% in math, and 3% in science. The central finding is a sharp split: graduation is high, while proficiency is very low across all three tested subjects.

Delta’s graduation rate is a bright spot: it was higher than the district’s 92% and the state’s 88%, and was second-highest among nearby schools with reported rates, behind only Central Coast New Technical High at 100%. Delta’s 3% dropout rate was also below the district’s 6% and state’s 8%. Its test scores, by contrast, were well below the district and state: ELA was 17% versus 47% and 49%, math was 0% versus 19% and 38%, and science was 3% versus 29% and 36%. Delta also trailed the averages for the nine nearby schools with reported scores: 43% in ELA, 19% in math, and 30% in science. Its math score tied Maple High for the lowest among nearby schools with results.

ELA has improved since 2022–23, rising from 10% to 17%, while math remained at 0% and science was essentially flat at about 3%; state results rose in all three subjects over that period. SchoolDigger gives Delta 0 stars and ranks it at the 8th percentile statewide, tied locally with Lopez Continuation High; only Maple ranks lower among nearby schools with a reported ranking. In 2024–25, 79% of Delta students were free/reduced lunch eligible, and its student-teacher ratio was 20.7, higher than most nearby schools. The reported 2025–26 chronic-absenteeism figure is 93%, compared with 22% in the district and 18% statewide, so families may want to clarify how that measure is defined for Delta.
