Summary:

The Cassia County Joint District serves about 1,802 students across five high schools in rural Idaho, including the large traditional Burley Senior High School and Declo Senior High School, along with three smaller 7-12 junior/senior high schools: Oakley Junior/Senior High School, Raft River Junior/Senior High School, and Cassia Junior/Senior High School. The district ranks 64th out of 101 Idaho districts and carries a 2-star rating, with roughly 44% of students qualifying for free or reduced-price lunch.

The five schools differ dramatically from one another. Oakley Junior/Senior High School is the strongest overall performer, with the highest proficiency rates in math (54.5%), science (41.4%), and English language arts (61.6%), and it ranks 61st among 122 Idaho high schools. Declo Senior High School is a standout in reading, posting 76.5% proficiency on the end-of-course ELA exam, and has the district's lowest chronic absenteeism rate (3.1%); however, its math scores (23.5% EOC) are well below state averages. Raft River Junior/Senior High School also shows solid ELA results and the lowest student-teacher ratio in the district (10.5:1). In contrast, Burley Senior High School, the largest school at 1,031 students, struggles across all subjects, and Cassia Junior/Senior High School presents the greatest challenges, with 75.9% poverty, 43.4% chronic absenteeism, and just 21.4% ELA proficiency.

Several patterns stand out. Smaller schools tend to outperform Burley in reading, though Cassia demonstrates that small size alone does not guarantee success. Notably, higher per-student spending does not translate into better results: Burley spends the most ($8,612 per student) yet posts some of the lowest scores, while Oakley spends the least ($8,237) and achieves the most. School rankings have also shifted considerably from year to year, making it important to look at multiple data points. The clearest opportunities for improvement are math instruction at Declo and Burley, and addressing Cassia's absenteeism crisis before academic gains can take hold.
