The Acellus Learning System

Acellus was created with the goal of making a science of the learning process. Acellus operates as a comprehensive system which delivers instruction to students by computer, manages assignments, provides student assessments, and maintains student records.  More importantly, Acellus provides an array of advanced features enabling it to diagnose deficiencies in student understanding, to provide customized personal instruction when needed, and to constantly analyze the effectiveness of the teaching process.

The human mind is an amazing thing – no two are alike. This makes the task of teaching such a dynamic range of developing minds quite a difficult undertaking. In order to create educational material that will cater itself to students of all ages, backgrounds, and mental capacities, we have turned to science for the answers. Acellus is the “science of learning.”

Mission Acellus

Acellus is now used throughout the US at more than 15,000 schools, both public and private.  In the preferred deployment, it is used as part of a blended learning system where instruction is provided over Acellus as well as by qualified teachers at the local school.

The Acellus live monitor provides live student progress reports and sends alerts to both teachers and parents when a student struggles or fails to make progress in a course.
