Summary
Harney Kathleen & Tim Middle School is a large Clark County School District middle school in Las Vegas, NV, serving grades 6–8 with 1,292 students. In 2025–2026, it ranked 146th of 148 Nevada middle schools, at the 1st percentile with 0 stars, even though the Clark County district is ranked 5th of 12 in Nevada at the 58th percentile with 4 stars. The school’s rank has fallen sharply over the past decade, from the 39th percentile in 2017–2018 to the 1st percentile now.
For 2025–2026, all-grade proficiency was 10.4% in Math, 19.5% in Reading, and 11.7% in Science—far below district and state averages. Among nine nearby same-district middle schools, Harney had the lowest Math and Science scores, and its Reading score was third-lowest, behind Bailey Dr William H Middle School (19.2%) and Mack Jerome Middle School (19.4%). Chronic absenteeism was 37.4%, compared with 27.0% in the district and 25.5% statewide; it has improved from 56.8% in 2021–2022 but remained the second-highest among nearby peers, behind Cortney Francis H Junior High School (39.1%). Math proficiency has edged up from 5.9% in 2023–2024 to 10.4% in 2025–2026, but Reading has stayed around one-fifth proficient, and Science has dropped from 18.1% to 11.7%.
Resource measures are also less favorable than those of nearby same-district peers: Harney has the highest student-teacher ratio (24.8) and the lowest per-student spending ($11,614) among them. All nearby same-district schools report 100% free/reduced lunch, so Harney is not unique in serving an economically disadvantaged population. O'Callaghan Mike Middle School i3 Learn Academy also reports 100% free/reduced lunch but has much lower chronic absenteeism (11.8%), a lower student-teacher ratio (22.8), slightly higher spending ($12,282), and much higher proficiency (Math 44.3%, Reading 55.4%, Science 48.7%); Harney trails by about 33.9 points in Math, 35.9 points in Reading, and 37.0 points in Science. The bottom line is that Harney is at or near the bottom of its peer group and the state, with some improvement in absenteeism and Math but still very weak Reading and Science and a long-term negative trajectory.
