Schools in Zip Code 83622

Schools in ZIP code 83622 include just one school: Garden Valley School, a PK–12 alternative school serving 220 students in the Garden Valley District. As the only school in this rural Idaho ZIP code, Garden Valley School acts as the community’s single educational pipeline, covering every grade from Pre-K through 12th grade on one campus. It is an alternative school with a student-teacher ratio of 13.4 to 1, and nearly half of its students (45.45%) qualify for free or reduced-price lunch.

Because there is only one school, all comparisons are made against state benchmarks rather than local peers. The school’s biggest academic strength is science: in 2025–2026, 50.9% of all students scored proficient in science, well above the state average of 42.7%, and the End of Course science rate (50.0%) also exceeded the state (41.2%). The previous year, science was 40.4% versus the state’s 42.6%, showing improvement. Math and English language arts are more challenging, with every reported grade-level score in 2025–2026 falling below state averages—for example, 6th grade math was 29.4% versus 42.5%, and 7th grade ELA was 31.3% versus 56.8%. However, the schoolwide ELA result in 2024–2025 was actually above the state (57.4% vs. 53.9%), so performance varies by grade and year.

The school also posts a graduation rate of 82.5%, exactly matching the state average, which is a meaningful accomplishment for an alternative school serving a wide grade span. The biggest concern is chronic absenteeism, reported at 28.0% in 2024–2025—roughly twice the state average of 13.8% and higher than the district’s 20.2% rate from 2025–2026. Given its small enrollment, proficiency rates can swing sharply from year to year, and the per-pupil spending figure of $12,986 is from 2018–2019 and should be interpreted with caution. Overall, Garden Valley School is a bright spot in science and graduation, but it faces clear challenges in attendance and secondary math and reading that families should keep in mind.
