Summary:
Zip code 83210 in Idaho is served by one public high school, Aberdeen High School, which enrolls 213 students in grades 9–12 as part of the Aberdeen District.
Aberdeen High School presents a mixed picture for parents. The school’s strongest area is English Language Arts: in 2024–2025, 66.7% of students were proficient, well above the state average of 53.9% and far above the district’s 44.5%. Attendance is also a relative positive, with chronic absenteeism at 13.0% in 2025–2026, slightly better than the state’s 13.8%. The student-teacher ratio of 13.4 suggests reasonably small class sizes, and the graduation rate of 82.5% matches the state average. However, math and science proficiency lag significantly. In the most recent End of Course tests, only 18.9% of students were proficient in math and 24.5% in science, compared to state rates of 33.1% and 41.2%. This is a sharp drop from the previous year’s all-grades proficiency rates of 31.0% in both subjects, and it helps explain why the school’s ranking fell from the 52nd percentile (3 stars) in 2023–2024 to the 22nd percentile (1 star) in 2025–2026. Notably, Aberdeen’s graduation and attendance metrics did not decline over that period, pointing to test scores—particularly in STEM—as the main driver of the ranking change.
Parents should also know that Aberdeen High School serves a predominantly low-income student population, with 68.54% of students eligible for free or reduced-price lunch. Many school-level figures—including graduation rate, test scores, and chronic absenteeism—exactly match district-level data, which is consistent with Aberdeen High School being the only high school in the district. The bottom line: this is a small, high-need school with clear literacy strengths but a pressing need for targeted support and improvement in math and science instruction. Given the recent declines, families may want to ask about STEM course offerings, intervention programs, and test preparation strategies.
