The data story: Portland Arthur Academy Charter School vs Bridger Creative Science School

Who each school fits
Portland Arthur Academy Charter School
Bridger Creative Science School suits families who prioritize exceptional academic growth trajectory — its 9.7/10 growth score is seven-tenths of a point above Arthur Academy's — and who want a K–8 path that eliminates a middle school transition. It also fits parents who value a larger, more socioeconomically diverse community and are comfortable with a slightly higher student-teacher ratio in exchange for that breadth.
Bridger Creative Science School
Portland Arthur Academy Charter School fits families who weight raw academic achievement above growth rate, given its 9.3/10 academic score versus Bridger's 8.4/10. The smaller enrollment of 164 students and a 16.4:1 student-teacher ratio appeal to parents who want a tighter-knit setting. Families should be prepared to research middle school options before fifth grade, as Arthur Academy's K–5 span ends earlier.
