Summary:
Manteca has 18 schools: 13 elementary schools serving kindergarten through grade 8, and five high schools, including one serving grades 7–12. The elementary schools average 33% proficiency in English language arts (ELA), 23% in math and 20% in science, compared with state averages of 49%, 38% and 36%; high schools average 37%, 16% and 23%, respectively. Results vary sharply from school to school, especially in high-school ELA, where the gap between the highest and lowest results is 63 percentage points.
Nile Garden Elementary leads elementary schools in all three subjects, with 57% proficient in ELA, 51% in math and 47% in science—8, 13 and 11 points above state results. Sierra High leads high schools at 68% in ELA, 41% in math and 48% in science, also above the state in each subject. At the other end, Lincoln Elementary is lowest among elementary schools in every subject: 19% in ELA, 10% in math and 7% in science. Yosemite School Community Day has the lowest high-school ELA and math results, at 5% and 0%; Calla High has the lowest science result, at 6%. Yosemite’s grade span and alternative-school setting differ from those of the other high schools.
Recent changes are mixed: elementary math and science averages each rose about 1 point, but the state improved faster, while high-school ELA fell 8 points; high-school math and science increased about 1 and 3 points. SchoolDigger statewide rankings rose from the 63rd to the 72nd percentile for Nile Garden and from the 73rd to the 80th for Sierra, while George McParland Elementary and Stella Brockman Elementary fell from the 41st to 30th and 32nd to 16th percentiles. School context does not neatly track results: Nile Garden’s student–teacher ratio is 27.7, compared with 11.9 at Calla, and their achievement differs substantially. Reported free/reduced lunch eligible shares for 2024–25 were 55% at Nile Garden and 79% at both Shasta Elementary and Sequoia Elementary; these figures are context, not an explanation of school results.
