Middle Schools in Petersburg Borough School District

In the Petersburg Borough School District, located in Petersburg, Alaska, there is exactly one middle school: Mitkof Middle School. Mitkof serves grades 6 through 8 with an enrollment of 114 students, averaging roughly 38 students per grade level. About 66.67% of students qualify for free/reduced lunch, and the school has a student-teacher ratio of 16.5 with per-student spending of $18,359. The district itself ranks 7th out of 23 Alaska districts, placing it in the 70th percentile with a 4-star rating. Because Mitkof is the sole middle school, there are no intra-district middle school comparisons; instead, meaningful comparisons are drawn against Alaska state averages, district-wide figures, and Mitkof's own recent performance.

Mitkof Middle School has consistently placed in the upper third of Alaska middle schools, with rankings ranging from the 67th percentile (3 stars) in 2025-2026 to the 84th percentile (4 stars) in 2024-2025. Its clear academic strength is science: in 2025-2026, 67.57% of Mitkof 8th graders were proficient in science, compared to 35.17% statewide — a remarkable +32.4 percentage point gap. The school also beats the state average in English Language Arts (47.71% vs. 32.89%) and mathematics (41.67% vs. 32.20%). Grade-level math results show an unusual pattern: 6th grade math proficiency is 36.84%, 7th grade falls to 32.26% (essentially tied with the state average), and 8th grade jumps to 53.85% — 20.5 points above the state average.

All subjects declined at Mitkof Middle School from 2024-2025 to 2025-2026: math dropped 8.33 percentage points, science fell 5.16 points, and ELA slipped 3.31 points. With only about 38 students per grade, these shifts should be interpreted carefully, as a change of just a few students can move proficiency rates noticeably. Mitkof's math proficiency appears slightly below the district-wide "all grades" average, but because Mitkof is the only middle school, that comparison simply reflects test results from other grades and school levels within the broader district. Despite two-thirds of its students facing economic disadvantage, Mitkof outperforms the Alaska state average in every tested subject, making it a solid academic choice in a small, rural community. Families should monitor the recent declines — particularly in math — while keeping in mind that small enrollments naturally create year-to-year volatility.
