Summary:
Zip code 83837 in Kellogg, Idaho, contains just one high school – Kellogg High School – which serves grades 9 through 12 with an enrollment of 289 students and is part of the Kellogg Joint District. As the only high school in the area, Kellogg High School's performance defines secondary education in this community, and it shows signs of both progress and persistent challenges.
Kellogg High School has improved its state ranking significantly, jumping from 106th out of 112 schools in 2024–2025 to 87th out of 122 in 2025–2026, moving from the 5th to the 29th percentile. In math, the school's End-of-Course proficiency rate of 32.8% is nearly identical to the state average of 33.1%, but English Language Arts proficiency (51.7%) trails the state (61.3%) by nearly 10 points. Science is the most concerning subject, with only 26.7% of students proficient compared to 41.2% statewide, representing the largest gap among core subjects. The graduation rate is 82.5%, meaning roughly one in five students does not graduate on time. Previous-year all-grades math scores were far lower at 20.4% versus the state's 43.1%, though this is a different metric from a different school year.
The school serves a community with moderate economic need, as 46.71% of students qualify for free or reduced lunch. With a student-teacher ratio of 13.9, class sizes are relatively small, which may offer opportunities for individual attention. Chronic absenteeism data is somewhat inconsistent, with the school reporting 11.4% in 2023–2024 while the district shows only 0.6% more recently, compared to a state rate of 13.8%. Because enrollment is just 289 students across four grade levels, year-to-year metrics can swing noticeably with the performance of a single cohort. Overall, Kellogg High School is a small, moderately high-need school making uneven but potentially upward progress, with science standing out as the clearest academic priority for improvement.
