School Overview
Portland Arthur Academy is a public charter school located in the Montavilla neighborhood of Southeast Portland, serving students in grades K–5. It is part of the Arthur Academy network, a small group of tuition-free charter schools in Oregon that utilize the Direct Instruction (DI) model. This pedagogical approach is characterized by highly structured, teacher-led lessons, fast-paced instruction, and frequent assessments to ensure mastery of core academic skills, particularly in reading, math, and language arts.

The school is widely recognized for its "back-to-basics" academic philosophy, which prioritizes core curriculum and a disciplined, supportive classroom environment. Because it is a public charter, it operates independently of the traditional district curriculum, allowing it to maintain a consistent, research-based instructional focus across all grade levels. Its mission centers on providing a rigorous academic foundation designed to help all students—regardless of their starting point—reach or exceed grade-level proficiency before transitioning to middle school.
