Summary

Nathaniel S. Colley Senior High serves 111 students in grades 7–12 in Sacramento, within the Sacramento County Office of Education. The most concerning picture is that low test results accompany low graduation and high dropout rates: in 2025–26, 29% of students graduated, compared with 41% in the district and 88% statewide, while 26% dropped out. The graduation rate was 27 percentage points below the lowest nearby-school rate, and the dropout rate was 17 points above the state rate.

In 11th-grade tests, Colley was below every nearby school in English, tied for the lowest in math, and third-lowest in science. Its 2025–26 scores were 0% in English, 0% in math, and 4% in science. Across nearby schools, average scores were 33% in English, 15% in math, and 19% in science. Science is Colley’s relative strength compared with state results: across all grades, its science score was 4%, versus 0% in English and math, but all three remained far below state averages of 36%, 49%, and 38%, respectively. Compared with the district, math was closest, with a 3-point gap; English had the largest gap, at 8 points. Half of Colley’s students were chronically absent in 2025–26, versus 37% in the district and 18% statewide.

Results have generally moved in the wrong direction: from 2022–23 to 2025–26, English fell from 17% to 0% and math from 9% to 0%, while the state improved in both subjects. Colley’s gaps with the state widened by 19 points in English and 12 points in math. Science declined from 9% in 2023–24 to 4% in 2025–26, despite a small recent improvement. SchoolDigger places Colley in the 12th percentile and gives it 1 star; its percentile fell from 24 in 2023–24. The school has the highest nearby student-teacher ratio, 33.1, compared with a nearby average of 18. Its 2024–25 free/reduced lunch eligible rate was 70%, below the nearby-school average of 76%. With just 111 students, school-level percentages can be sensitive to the number of students tested.
