Summary:
Lake Chelan School District has two high schools serving grades 9–12 in the Lake Chelan area of Washington: Chelan High School and Chelan School of Innovation. Together, they enroll about 489 students, with the traditional high school serving nearly 90% of them. The district ranks around the middle of Washington districts overall, with a three-star rating, and its strongest broad outcome is graduation: 95.8% of students graduate, compared with 82.6% statewide.
Chelan High School is the larger, comprehensive campus and has the most complete recent performance information. Its latest ranking improved substantially, rising from the 38th to the 55th percentile and from two stars to three stars. The school’s previous reported graduation rate was an excellent 96.4%, and its 2025–26 academic results show particular strength in English language arts, where 57.76% of students were proficient. Science proficiency was 46.08%, while math was lower at 33.62%. Math is the main improvement priority, although it increased nearly nine percentage points from the prior year. The school also has a lower reported student–teacher ratio than Innovation, at 17.5:1.
Chelan School of Innovation is a much smaller program with 50 students. Its 2024–25 ELA proficiency rate of 75% was notably higher than both district and state results, but the small enrollment means a few students can significantly affect percentages. The state suppressed the school’s 2025–26 test results, so current academic comparisons are limited. Its graduation rate was 89%, still above the state average but below the district’s rate. Families comparing the schools should weigh Innovation’s smaller setting and promising ELA result against its limited recent data and much higher reported student–teacher ratio of 33.3:1.
