Summary

Del Norte Elementary is a K–6 school in Ontario, California, serving 428 students in Ontario-Montclair. In 2025–26, its proficiency rates were below both district and state averages in English language arts (ELA), math, and science. The clearest concern is science: just 18% of students were proficient, 18 percentage points below the state.

ELA is Del Norte’s strongest subject compared with nearby schools: 40% proficiency ranked fifth among 11 schools, though the result was 7 points below the district and 10 below the state. Math proficiency was 26%, 11 points below the district and 13 below the state, placing eighth among the 11. Science was the weakest nearby comparison: Del Norte ranked second-lowest, ahead of only Los Amigos Elementary. Sixth grade is a particular concern: its math proficiency was 20%, the lowest among nearby schools reporting sixth-grade results and 17 points below both district and state rates. By contrast, fifth-grade ELA was the school’s strongest grade-level result at 43%.

Results have moved in different directions: from 2022–23 to 2025–26, ELA rose 9 percentage points to 40%, math was nearly unchanged at 26% (up 2 points), and science fell 2 points to 18%. SchoolDigger ranked Del Norte at the 33rd statewide percentile with 2 stars in 2025–26, up from the 24th percentile and 1 star the prior year; the district ranked at the 56th percentile with 3 stars. Del Norte’s student-teacher ratio was 21.4 in 2024–25, close to the nearby average of 22.0, and 93% of students were free/reduced lunch eligible that year. SchoolDigger’s 2025–26 measure for Homeless Students placed the school at the 82nd percentile, compared with its overall 33rd percentile; for Special Education Students, it reached the 46th percentile, up from the 13th percentile in 2023–24. Subgroup rankings do not include student counts, so year-to-year shifts may be sensitive to how many students were represented.
