Apex Learning Tutorials significantly improved student performance on Tutorials posttest assessments across English, math, science, and social studies for three straight years.

Tutorials had a statistically significant impact on student posttest achievement compared to pretest performance for all school years by subject. Results of paired-samples t-tests suggested that by subject, the average gain across school years for English was 75%, followed by math at 66%, science at 56%, and social studies at 63%. 

The average gain by subject was consistent across years fluctuating between +/-.28 and +/-2.21 percentage points. For English and math, the results of one-way ANOVAs suggested that gains made in the 2017-2018 and 2018-2019 school years were greater than gains made in 2016-2017. For science and social studies, the average gain made in 2018-2019 was not significantly different than the gain made in 2017-2018.
