This study aimed to evaluate the efficacy of the Repeated Reading and Visual Comprehension Program (TOGAP) developed to support the reading comprehension skills of primary school students with specific learning disabilities (SLD) in the 2nd, 3rd, and 4th grades. The research was conducted with four primary school students with SLD. The changing criterion design, one of the single-subject research designs, was utilized. Results yielded that TOGAP, developed within the scope of this study, was effective in the development of reading comprehension skills of three out of four participating students with SLD. TOGAP, targetted primary school students with SLD, is effective primarily in improving reading comprehension skills as well as increasing the number of correct words read per minute, and the rate of reading accuracy. Social validity data that shows satisfaction of all stakeholders from TOGAP, contributed to the literature in addition to quantitative data which presented the effectiveness of the program. TOGAP is suggested to be used in resource rooms in schools and special education and rehabilitation centers; to be adapted to tablets, computers etc., and to be used with students with various special educational needs.
