Summary:
ZIP code 89128, in northwest Las Vegas, is served by exactly one public high school — Cimarron-Memorial High School — a large campus of about 2,483 students in grades 9 through 12 and part of the Clark County school district, the only neighborhood high school option for families in this ZIP.
Its clearest strength is getting students across the graduation stage: 92.0% of students graduated in 2024-2025, above both the district (86.6%) and Nevada (85.4%) averages — a notable result given that 100% of students qualify for free or reduced-price lunch, meaning the entire student body is classified as economically disadvantaged. Test scores, however, tell a different story. On the 11th-grade ACT, 6.5% of students were proficient in math and 31.7% in English, compared with district rates of 22.3% and 51.2% and state rates of 22.6% and 50.8%. The math gap stands out: English proficiency here is roughly five times the math rate, while statewide that imbalance is only about 2.2 to 1.
Chronic absenteeism is the largest concern in the data: 42.5% of students were chronically absent in 2025-2026, versus 27.0% district and 25.5% statewide — about two in five students. Statewide, the school ranked 94th of 105 high schools, in the 10th percentile with 1 star, slipping from its 2024-2025 position. Some 2025-2026 science results are suppressed by the state, so the academic picture is incomplete. Student-teacher ratio is 21.7 to 1 and per-student spending was $11,632 in 2023-2024, though the data offers no district or state comparison for those two figures.
