Acellus

Acellus is a personalized, video-based K-12 learning program used by over one million students across every U.S. state. Whether your student is in school, homeschooling, or learning virtually, Acellus meets them exactly where they are.

Every student learns differently. Short video lessons introduce each concept, followed by practice problems that adapt to how your student is progressing — a dynamic learning experience built around the individual, not the classroom average.

Learn at Their Own Pace

Students work independently through concepts, with personalized instruction that helps them truly master each one before moving on. No one gets left behind, and no one is held back.

Acellus covers all core subjects — math, reading and language arts, science, and social studies — plus Advanced Placement (AP), Exceptional Education, Career & Technical Education, and exam preparation. With over 470 courses, students from kindergarten through 12th grade follow a full, standards-based path.
