Student achievement in reading comprehension has been an important topic for the past several years due to the importance of reading in education. School districts in South Carolina have had enormous amounts of pressure put on them to increase student reading comprehension through the implementation of SLOs and the Read to Succeed initiative. The School District of Pickens County has chosen to use the Accelerated Reader program in an attempt to help boost student reading comprehension. The quasi-experimental design was used during the quantitative research process to determine the effect of Accelerated Reader on student reading comprehension and student achievement. The measuring instrument used was student MAP test data from the 2014-2015 and 2015-2016 school years. Overall RIT scores of students were compared during the Fall, Winter, and Spring administrations of MAP during both school years. The results of the study showed an increase in overall RIT for both the experimental and control groups, but there was no significant increase in student reading comprehension with students systematically exposed to Accelerated Reader and students that were not.
