Summary:
Zip code 81090 is served by a single high school, Walsh High School, a small rural school in Walsh School District No. Re-1 that serves grades 7 through 12 with 72 students and a high poverty rate of 65.28% free/reduced lunch. Because it is the only high school in the area, its performance essentially defines the district's results, and the data should be viewed through the lens of a very small student body.
Walsh High School posts an 80.0% graduation rate (2021-2022), below the state's 85.6%, while its 1.7% dropout rate is right in line with the state's 1.6%. One clear strength is attendance: the school's chronic absenteeism rate is 15.1%, roughly half the state average of 28.4%, even though the school serves a high-poverty population. Academically, CMAS proficiency trails the state across the board. In 2025-2026, ELA proficiency was 28.6% versus 44.7% statewide, and math was just 14.3% versus 37.3% statewide. Eighth-grade science came in at 21.1% compared to 35.4% statewide.
Notably, the school shows a persistent gap between literacy and math: ELA proficiency (28.6%) is double the math rate (14.3%), and both subjects dropped from the prior year (40.7% ELA and 18.5% math in 2024-2025). With only 72 students, those swings can reflect just a few kids. The school does offer a favorable 12.7:1 student-teacher ratio, which supports individualized instruction. Overall, Walsh High School keeps students engaged and attending at strong rates, but academic proficiency, especially in math and science, remains well below state averages.
