Summary
Excelsior Academy is a large K–8 charter school in Erda, Utah, serving approximately 1,406 students in a growing area near Tooele, with a broader grade span and nearly twice the enrollment of many nearby elementary schools. Its latest statewide ranking places it 252nd of 563 Utah schools, in the 55th percentile, a substantial improvement from the 34th percentile in 2020–2021. The school’s district ranking is 48th of 92 districts, or approximately the 48th percentile.
Academically, Excelsior Academy is generally stronger than most nearby schools, although results vary by grade. Mathematics is a clear strength in grades 3–5, where proficiency ranged from 52.5% to 60.9%, and science was especially solid in grades 4–6. The school’s overall mathematics results in grades 3–8 averaged approximately 44.6%, compared with roughly 36.4% statewide. Excelsior’s ranking trails Stansbury Park School, which ranked in the 61st percentile, but it generally compares favorably with Middle Canyon School, Rose Springs School, and most other nearby schools. Its English language arts results are competitive locally but uneven across grades.
The most urgent concern is eighth-grade mathematics: proficiency was 17.5%, far below Utah’s 39.3% rate and much weaker than Excelsior’s elementary mathematics results. Seventh-grade science was another relative weakness. In contrast, chronic absenteeism fell to 16.4% in 2024–2025, below Utah’s 23.8% rate and better than most nearby schools, including Old Mill School and Northlake School. Parents may also want to ask about staffing: the reported student-teacher ratio is unusually high, though it may reflect reporting methods rather than actual class sizes. Overall, Excelsior shows meaningful progress, strong elementary math and science, and favorable attendance, while middle-school consistency—especially eighth-grade math—needs attention.
