Schools in Zip Code 83335

ZIP code 83335 covers the Hazelton, Idaho area and is served by just 2 schools: Valley School and Cornerstone High School, both part of the Valley District. Valley School serves grades PK-12 with 493 students, while Cornerstone High School serves grades 9-12 with only 6 students. The two schools share the same address at 882 Valley Road South.

Valley School is the dominant institution in the area and is the only school with standardized test data. It exceeds state proficiency in 4th grade math (60% vs. 48%) and 4th grade ELA (64% vs. 50.2%), reflecting strong early instruction. However, proficiency drops sharply at the secondary level, with 7th grade math at 18.2% versus the state's 43.6% and End of Course ELA at 35% versus 61.3%. Positively, Valley School posts a chronic absenteeism rate of just 6.0% — less than half the state average of 13.8% — and a graduation rate of 82.5% that matches the state, all while serving a student body where 58.4% qualify for free/reduced lunch.

Cornerstone High School offers a very different profile. With 6 students and a 5:1 student-teacher ratio, it provides nearly one-on-one instruction, but its graduation rate was just 57.1% in 2023-2024, well below the state average of 82.5%. Its historical chronic absenteeism rate of 35% may help explain this, though no recent data is available, and no test scores are reported due to the tiny enrollment. For parents, the key takeaway is that Valley School excels in elementary grades but declines in middle and high school, suggesting secondary students may need extra support. The most recent spending data shows $9,154 per student at Valley School in 2018-2019.
