Summary
Bonanza High School is a comprehensive 9–12 high school in Las Vegas serving 1,858 students in the Clark County School District. In 2025–2026 it ranked 88th of 105 Nevada high schools (16th percentile, 1 star), far below its district’s 4-star, 58th-percentile profile. Economic need is nearly universal: free/reduced-price lunch participation was 99.95% in 2022–23 and 100% in 2023–24 and 2024–25. Per-student spending rose from $8,448 in 2020–21 to $12,334 in 2023–24, while the student-teacher ratio fell from 24.6:1 to 18:1.
Bonanza’s proficiency is low overall, and math is the clearest weak spot. In 2025–2026, 6.8% of 11th graders met ACT Math benchmarks, versus 22.3% in the district and 22.6% statewide; ACT English was 30.0%, versus 51.2% and 50.8%. End-of-Course Science was 20.2%, compared with 27.0% and 26.5%. By contrast, the 91.9% graduation rate (2024–25) beats the district’s 86.6% and the state’s 85.4%. Chronic absenteeism is 40.0%, above the district’s 27.0% and state’s 25.5%, but down from 54.2% in 2021–22. Among large nearby comprehensives, Bonanza is the smallest and best-funded, with the lowest student-teacher ratio. Spring Valley High School posts stronger results—62nd percentile, 68.0% ACT English, 35.5% science, 28.6% absenteeism—on lower per-pupil spending ($10,394). Western High School and Cimarron-Memorial High School sit lower on many measures. Two small grades-11–12 programs are essentially next door: College of So NV High School West (93rd percentile) and Nevada State High School Summerlin (94.8% graduation).
The main takeaway is that Bonanza High School graduates students at a rate its test scores do not predict, suggesting completion-focused supports rather than demonstrated mastery. English proficiency has improved, but math has stayed essentially flat while the district’s math proficiency rose, so the math gap is widening. A reported science “surge” is encouraging but not fully verifiable because of reporting changes. Attendance is the most improved and likely most fixable metric; closing the remaining gap to the district’s 27% could be high-leverage. Subgroup performance is broadly weak: low-income students ranked 6th percentile in 2025–26. The district’s rating does not describe this campus. Families should weigh Bonanza’s strong completion and improving attendance against low proficiency, especially in math.
