Summary:
Zip code 83346 is home to just one high school, Oakley Junior/Senior High School, a small school serving 179 students in grades 7–12 within the Cassia County Joint District. Because there are no neighboring schools for comparison, this analysis focuses on how Oakley measures up against district and state averages.
Oakley is a strong performer in core academic subjects. In 2025–2026, math proficiency reached 54.5% at all grades, well above the district's 37.1% and the state's 43.1%, while English Language Arts came in at 61.6%, beating both the district (44.6%) and state (54.0%). The school shines brightest in the middle grades: 69% of 7th graders were proficient in math, and 8th-grade science proficiency hit 51.4%, compared to 42.9% statewide. This success is supported by good attendance, with only 10.1% of students chronically absent, and a favorable 12.9:1 student–teacher ratio, all achieved while serving a population where roughly 41% qualify for free or reduced lunch.
However, Oakley faces clear challenges. Science proficiency at the high school level is a notable weakness, with End-of-Course science at just 31.4% versus 41.2% statewide, and End-of-Course ELA also trails the state (57.1% vs. 61.3%). The graduation rate of 82.5% is exactly average, meaning about one in six students does not graduate on time. The school's state ranking has also slipped from a 4-star, 72nd-percentile rating in 2023–2024 to a 3-star, 50th-percentile rating in 2025–2026. If Oakley can carry its impressive middle-grade results into high school coursework and boost graduation rates, it has strong potential to regain its former standing.
