Westlake High in Saratoga Springs is the biggest high school in Utah County, with 3,303 students in the state's Oct. 1, 2025 count. The next three are also in Alpine School District's fast-growing north and west: Cedar Valley (2,649), Skyridge (2,644) and Lone Peak (2,436). Meanwhile, all three of the county's big school districts lost students for the year.
Enrollment figures are from the Utah State Board of Education's Fall Enrollment by Grade Level report for school year 2025-26 (the Oct. 1, 2025 count) and its enrollment-by-district report with October 2026 projections, downloaded Nov. 7, 2026.

Read the sizes with grade levels in mind
The schools don't all cover the same grades. In the state data, Timpview and Provo High enroll a full ninth grade (597 and 466 ninth-graders), so they're 9-12 schools. Alpine and Nebo high schools have almost no ninth-graders; ninth grade is in junior high, so they're effectively 10-12. A 2,300-student Alpine high school is therefore larger per grade than a 2,300-student Provo school.
District totals
| District | Oct. 2021 | Oct. 2024 | Oct. 2025 | Change, 2024-25 | Projected Oct. 2026 |
|---|---|---|---|---|---|
| Alpine | 83,999 | 84,757 | 84,215 | -542 | 83,000 |
| Nebo | 35,454 | 42,946 | 41,675 | -1,271 | 41,000 |
| Provo | 13,623 | 13,463 | 13,010 | -453 | 12,750 |
The state's report projects all three will shrink again in fall 2026. Statewide, district enrollment fell 2.7% from October 2024 to October 2025, to 571,106, while charter enrollment grew to 85,204, and the state projects charters to grow another 4.1% in 2026. Total Utah public-school enrollment, 656,311, fell for the second year in a row.
Nebo's count in the state's table jumped from 36,229 in October 2022 to 43,672 in October 2023 and has declined each year since.
What it means for families
- The growth is on the edges. The county's largest high schools serve Saratoga Springs, Eagle Mountain, Lehi and Highland, the same cities driving population growth in our Utah County cities by population rankings.
- Alpine is splitting. Westlake, Cedar Valley, Skyridge, Lone Peak, Lehi and American Fork will belong to new districts after Alpine dissolves on June 30, 2027; see our guides to Aspen Peaks, Lake Mountain and Timpanogos school districts.
- Provo and Orem are shrinking. Orem High, at 1,240, is the smallest of the comprehensive high schools.
