The purpose of this quantitative study was to improve the academic success of students through the utilization of differentiated teaching within a specialized Learning Resource Center. The research study site is a private coeducational K-11 school located in Northern Georgia. The school provides motivated and disciplined students with a rigorous and balanced liberal arts college preparatory education while emphasizing every student's social, physical, and spiritual well-being. The school administration was concerned that students who struggled with the rigorous curriculum and academic demands of the school needed some type of intervention to improve their academic success. The results of this study will provide K-12 educational administrators with an understanding of the impact this teaching methodology has on student academic success when administered within a specialized learning center. Recommendations for further research on differentiated teaching methodologies within a specialized Learning Resource Center are provided.
