Summary:
ZIP code 99737 covers the Delta Junction area in interior Alaska and contains a single public high school: Delta Junction Senior High School. Part of the Delta/Greely School District, it serves grades 9 through 12 with an enrollment of 126 students, which means an average of roughly 30 students per grade. As the only high school in the ZIP code, it cannot be compared with nearby local schools; instead, the most meaningful comparisons are to district and state averages. The district itself is currently ranked 4th of 23 Alaska districts, placing it in the 83rd percentile.
Delta Junction Senior High School has ranked in the upper half of Alaska high schools in recent years, but with noticeable movement: it earned a 5-star 6th-place ranking in 2024-2025, slipped to a 4-star 19th-place ranking in 2025-2026, and ranked 26th in 2023-2024. Looking at the latest grade-specific results, the school outperforms both district and state in every subject. Ninth-grade English language arts proficiency is 47.37% versus 45.45% for the district and 31.23% for the state, an impressive 16-point advantage. Ninth-grade math proficiency is 24.32%, which sits above the state's 17.91% but is still lower than parents would want. Tenth-grade science proficiency is 38.89% versus 36.84% for the district and 33.03% statewide.
The biggest concerns are math and graduation. About 76% of 9th graders were not proficient in math, and the graduation rate of 73.9% means roughly one in four students does not graduate in four years. All three core subjects declined sharply from 2024-2025 to 2025-2026 — math fell nearly 13 points and science fell about 14 points — but with only 30 students per grade, these swings can be driven by just a handful of children. Overall, Delta Junction Senior High School offers small classes with a 10.5:1 student-teacher ratio and solid English language arts performance, but families should monitor its math results and graduation rate over multiple years before drawing firm conclusions.
