Portland Arthur Academy is a public charter school that delivers direct-instruction reading and math in a structured, sequential format, using the Reading Mastery phonics program for literacy and Connecting Math Concepts (CMC) for math. The curriculum is designed to ensure mastery of foundational skills before students move on to new concepts, with lessons broken into small, carefully sequenced steps.
Instruction is highly interactive, with rapid pacing, choral group response, and individual turns built into each lesson. Alongside the core DI programs (which cover reading, writing, spelling, language, and math) the school also offers science, social studies, physical education, music, and enrichment activities. The school's motto, "Pay attention. Work hard. Get smart.
Be proud." captures the no-frills, academically focused culture that defines the Arthur Academy model.
