As the only high school in this zip code, Chugiak High School is by default the standout, and it is a strong performer by Alaska standards. It earned a 4-star rating and jumped from the 57th to the 81st percentile in the statewide ranking, now placing 12th out of 62 Alaska high schools for 2025–2026. Its graduation rate of 94.2% far exceeds the Anchorage School District's 83.2%. On the most recent state assessments, Chugiak beat both the district and state averages in every subject: English Language Arts proficiency reached 44.89% versus 35.97% for the district and 32.89% for the state; math reached 37.33% versus 35.66% and 32.20%; and science reached 40.28% versus 39.06% and 37.81%. The school also serves a relatively economically advantaged community, with just 18.32% of students eligible for free or reduced lunch, and it operates with a student–teacher ratio of 23.1 to 1.

A few key trends stand out in the data. Most impressive is the math turnaround: proficiency soared from 22.41% in 2024–2025 to 37.33% in 2025–2026, moving from well below district and state averages to above both. Meanwhile, science proficiency declined from 46.7% to 40.28% while district and state scores stayed flat, so Chugiak lost part of its previous science edge even though it remains above average. English Language Arts is the school's biggest relative strength, running 12 percentage points ahead of the state. The ranking improvement to the 81st percentile came even with the science dip, reflecting the combined gains in math and ELA, the strong graduation rate, and solid performance relative to other Alaska schools. Altogether, Chugiak High School combines a high graduation rate, above-average test scores, and a rapidly improving state ranking, confirming its status as one of the stronger high schools in Alaska.
