Summary:
ZIP code 97058 contains exactly one high school: The Dalles High School, a grades 9–12 campus with 795 students at 220 E 10th St in The Dalles, serving families in North Wasco County School District 21.
The school's strongest results are in completion and attendance. Its 2024-25 graduation rate of 91.2% is 8.7 points above its district (82.5%) and 8.2 points above the state (83.0%). Chronic absenteeism is 32.5%, better than the district's 39.5% and slightly better than the state's 33.5% — though roughly one in three students is still chronically absent. In English Language Arts, 43.4% of 11th graders were proficient, above the district's 41.2% but just below the state's 46.0%. Mathematics is the clearest weakness: 16.2% proficiency, below the district (19.0% All Grades, 18.2% in 11th grade) and far below the state (32.9% All Grades, 22.9% in 11th grade) — less than half the state rate. Science stands at 19.0%, nearly tied with the district's 18.9% at 11th grade but 14.8 points behind the state's 33.8%.
Rank history shows a downward trend: 149th of 268 (44th percentile) in 2023-24, 172nd of 270 (36th) in 2024-25, and 187th of 271 (31st) in 2025-26, holding 2 stars each year. The district itself ranks 119th of 141 with 1 star and a 16th percentile, so the school is not the weakest part of its district. Context matters: 99.25% of students qualify for free/reduced lunch, per-student spending is $23,094, and the student/teacher ratio is 19.6. In short, students here graduate and attend at rates above district and state norms, while math and science proficiency lag well behind.
