Summary:
Coeur D'Alene Charter Academy Inc. is home to one high school, Coeur D'Alene Charter Academy School, serving grades 6–12 in Coeur D'Alene, Idaho, with 593 students and a student-teacher ratio of 17.8.
This single school is an elite academic institution by Idaho standards. In 2025–2026, math proficiency reached 87.5% versus the state's 43.1%, science reached 89.3% versus 42.7%, and English Language Arts reached 95.3% versus 54.0%. The school has earned 5 stars in each of the last three years, ranking as high as #2 among all Idaho high schools and placing its district at #1 out of 101. The strongest subject is ELA, with every tested grade level scoring above 94%. Science also improved dramatically, jumping from 79.7% to 89.3% in just one year. Even the weakest area—8th grade math at 81.9% proficiency—is roughly 40 points above the state average. Chronic absenteeism is better than the state average (11.4% vs. 13.8%), and per-student spending is $6,986.
However, there are a few important nuances. The graduation rate is exactly the state average at 82.5%, which is surprisingly modest for a school with such outstanding test scores. This could be due to student mobility, extended timelines for graduation, or how charter school cohorts are counted. Math proficiency also tends to slip slightly from 6th grade (92.2%) to 8th grade (81.9%) before rebounding in end-of-course exams (85.2%). While more than 1 in 9 students is chronically absent, the school’s overall performance remains exceptional. The lack of free/reduced lunch data makes it hard to assess socioeconomic diversity, but for parents seeking a high-achieving charter environment with consistent top-tier results, Coeur D'Alene Charter Academy School stands out as one of the very best options in Idaho.
