Summary:
ZIP code 99645 in Alaska’s Matanuska-Susitna Borough contains 15 schools serving roughly 8,700 students in grades PK-12, all part of the 4-star Matanuska-Susitna Borough School District. The mix includes eight elementary schools, a middle school, four high schools, and two alternative schools, plus several charter and specialized programs—meaning families have options ranging from traditional neighborhood schools to K-12 correspondence and college-connected academies.
The clear academic leader is Academy Charter School, a K-8 school ranked #2 in Alaska with 79.6% math proficiency, nearly 2.5 times the state average. Among traditional elementaries, Pioneer Peak Elementary stands out with strong science (74.7%) and math (62.5%) despite 39.4% of students qualifying for free/reduced lunch. Colony Middle School quietly outperforms Palmer Middle School in nearly every subject; for example, 6th-grade math proficiency is 52.9% at Colony versus 32.7% at Palmer. The two comprehensive high schools—Colony High School and Palmer High School—are comparable overall, with Palmer showing steady improvement in state rankings and a 92% graduation rate.
Graduation rates are highest at Mat-Su Middle College School (100%), while alternative schools like Mat-Su Central School (69.7%) and Valley Pathways (65.2%) serve harder-to-reach populations and need more support. Math remains the biggest concern at the high school level, with only about 1 in 4 freshmen scoring proficient at Colony or Palmer. Science is a relative strength across the area, with several elementary schools exceeding 60% proficiency. Overall, ZIP 99645 offers a genuine academic powerhouse in Academy Charter, solid traditional schools, and specialized alternative programs, but school performance is not uniform—families should consider each school’s mission and results carefully rather than relying on ZIP-code-level averages alone.
