this study aimed to verify the effectiveness of a diagnostic therapeutic program based on the response to intervention model (RTI) in diagnosing and Improving Mathematics among primary school Students with learning disabilities. The study sample consisted of (22) students with mathematics learning disabilities from the fourth grade of primary school. To achieve the study goal, a program was prepared based on strategies and methods of responding to the intervention model in three stages, and measuring the effectiveness of the program in diagnosing and treating mathematics disabilities. The researcher prepared achievement tests for mathematics disabilities to apply them in the pre- and post-measurement of each stage of the response to the intervention model. The program was implemented for two months with three meetings per week, each lasting 50 minutes .and it was found that there was no deterioration in the sample after the follow-up stage, which means that this stage is largely effective, and the study recommended the use of response to intervention programs in diagnosing and treating students with learning disabilities
