Summary
Dayton High School is a 9–12 comprehensive high school in Dayton, Nevada, serving 748 students as the largest school in the Lyon district, which itself ranks 10th of 12 districts statewide (17th percentile, 1 star). In 2025‑26 the school ranked 83rd of 105 Nevada high schools (21st percentile, 1 star), essentially unchanged from 85th of 103 the year before and 76th of 96 the year before that. Ten years ago the picture was different: Dayton was a 3‑star school at the 56th–67th percentile in 2015‑16 through 2017‑18, a decline of roughly 45 percentile points, with only 2020‑21 and 2021‑22 interrupting the slide.
The clearest strength is completion: Dayton's 91.7% four‑year graduation rate beats its district (85.7%) and the state (85.4%), and tops larger Washoe County schools such as Damonte Ranch High School (83.8%) and Nevada Connections Academy (82.2%). Achievement is the opposite story. ACT Math sits at 17.4% (state: 22.6%), ACT English at 30.1% (state: 50.8%), and EOC Science at 18.3% (state: 26.5%) — far behind Coral Academy High School (48.3% math / 84.2% English) and Galena High School (41.6% / 74.2%). Chronic absenteeism, at 36.9%, runs about 11 points above the state's 25.5% and has held at 35–39% for five straight years even as the state rate fell.
Importantly, Dayton's same‑district peer Silver Stage High School posts nearly identical results (30.3% English, 18.0% science, 49.1% absenteeism), pointing to district‑wide patterns rather than a single building. Spending has risen from $9,949 per student (2020‑21) to $11,810 (2023‑24), with a steady 22.4 student‑teacher ratio. Notably, ACT Math has improved from 10% to 17.4% over recent years while English slipped from 37.8% to 30.1%. Some science results are suppressed by the state (unknown, not zero), and Nevada Connections' math figure is reported only as under 5%.
