System 44®

Learn how System 44 can make an impact in your classrooms

Turn lives around with foundational reading

For students who are significantly behind or have learning challenges, success means more than improved reading scores. It means broader academic achievement, the pursuit of a college education, and a career path that allows them to reach their fullest potential.

Success means educators have the power to change the life trajectory not only for students, but also for their families and communities.

System 44® places all students, at any level, on a path to achievement and provides the foundational tools they need to achieve real success in school and life.

Michaela, Grade 4, Pennsylvania

Having been homeschooled through the third grade, Michaela entered Baker Elementary School as a fourth grader with an infectious enthusiasm for learning, but also as a beginning reader. With hard work and support from her teachers and family, she’s now closer than ever to being on grade. “Due largely to her participation and success in the program, Michaela now has many aspirations for her future,” noted her teacher.

Dwayne, Grade 7, Texas

Dwayne was a shy student. When he started in System 44 and Read 180, he had a lot of anger and frustration with his reading challenges. Dwayne reads everything now—science books, sports books, sometimes even comic books. System 44 and Read 180 helped him set his sights even higher than middle school. “I want to graduate middle school, high school, and college, so I can study business,” says Dwayne. We can’t wait to see how far he goes!
