The results of the third-party evaluation revealed that Apex Learning courses increase learning gains made by credit recovery students on the South Carolina High School Assessment Program (HSAP) for both school years.

To understand the impact that Apex Learning Comprehensive Courses make on the achievement of credit recovery students, Apex Learning and Dorchester School District Two partnered with a third-party evaluator to study the impact Apex Learning English language arts and math courses have on student performance on the South Carolina HSAP, a state assessment required for high school graduation. The study was initially conducted for the 2010-2011 school year and replicated for the 2011-2012 school year. In both years, researchers investigated the relationship between Apex Learning courses and English language arts and math performance on the HSAP.

Graphs 6 and 7 show the average percent correct score on Apex Learning embedded assessments by quartile. For both school years, a positive relationship was found between students’ percent correct scores on Apex Learning assessments and student performance on the HSAP.
