The Powerful Differentiator

Acellus® Learning Accelerator

Vectored Instruction

Vectored Instruction has changed the dynamic of online education. With this new breakthrough technology, students can master foundational skills that are pre-requisites to success in their current course of study. Vectored Instruction fills in the gaps within the credit level course, enabling students to complete their coursework with passing grades, and get on track for graduation.


"This differentiation Acellus provides allows students to work at their own pace in completing the course work appropriate for their level. Consequently, our students have been able to make gains of 2 to 3 years in a single semester. The amount of curriculum covered thus far is astonishing. The “on task” and “task completion” behaviors have increased tremendously. All of this would not have been possible without the Acellus Learning System."

— Troy Mircovich, Superintendent, Ingleside ISD, TX

Prism Diagnostics®

Prism Diagnostics identifies specific deficiencies in students’ understanding of core concepts and responds immediately with Customized Personal Instruction (CPI) videos for that precise deficit. The result is that every student receives personalized instruction – right at the moment when they need it most.

Using Acellus, Grain Valley R-V School District in Missouri has seen graduation rates climb to 99%.

“Our philosophy in the district is that all kids can learn. But all kids learn at different rates and different ways and we have to access all of that,'' Dr. Jeremy Plowman, Principal said. “Acellus provides us with a tool to do that rather than saying one size fits all.”

Success Zone

According to the Acellus “Success Zone” strategy, 100% of the students in a class CAN succeed at in learning. The challenge is to transform students who are stuck into successful learners. One of the principle goals of this tool is to empower the teacher with the data and intervention options they need to get students making progress.  The outcomes schools are seeing are improvements in attendance, course completion, diploma readiness, and college preparedness.


"Acellus has become a powerful resource for the students at our school. Acellus gives us the ability to meet the individual needs of each and every student in our building. From At-Risk students to Gifted & Talented, Special Education and the regular classroom setting, we have witnessed positive growth in reading, math and science."

— Gabriel Cervantes, Principal, Jefferson R-VII School District, MO

It’s Affordable

Acellus is about 1/14th the cost of most other online learning systems, so for the same amount that it would cost to put 100 students on a competing program, schools can put 1,400 students on Acellus.  As a not-for-profit, Acellus benefits from generous donations and can put those funds into the development of Acellus courses without passing on those costs to the schools.
