Summary:
In zip code 83335 (Hazelton, Idaho), there is exactly one high school: Cornerstone High School, which serves grades 9–12 with a current enrollment of only six students and is part of the Valley District.
Cornerstone High School stands out for its extremely small size and very low student-teacher ratio of 5:1, meaning students receive a high degree of personalized instruction. However, the school’s most recent graduation rate (57.1% for 2023-2024) is well below both the district and state average of 82.5% (2024-2025), though these figures come from different years. Chronic absenteeism is also a concern: the school reported a 35% rate in 2021-2022, compared to later district (6%) and state (13.8%) benchmarks. With only six students, each individual represents about 17% of the school population, so all statistics are highly sensitive to year-to-year changes—one student leaving or enrolling can dramatically shift percentages. The free/reduced lunch data for 2024-2025 was missing, leaving that indicator unavailable.
For parents, this is a school that offers intense, individualized attention in a very small, likely alternative or credit-recovery setting. The low student-teacher ratio is a clear strength, but the lower graduation rate and high chronic absenteeism suggest that students may face significant academic or engagement challenges. Because there is only one high school in this zip code, there are no direct local comparisons to other schools. The data provided is a snapshot with mismatched reporting years, so it would be wise to seek more current and consistently reported information before drawing firm conclusions about the school’s overall performance.
