With the reauthorization of the Individuals with Disabilities Education (Improvement) Act (IDEA) in 2004, local education agencies (LEAs) were no longer required to employ an IQ-achievement discrepancy model in the identification of a specific learning disability (SLD). Rather, districts were permitted to use data from a Response to Intervention (RTI) framework in determining a student's eligibility for special services under the SLD classification. Because this change in legislation has the potential to impact the ways in which schools provide services to students, it is important to review the research base that informs practice. This review of the trends in the RTI literature examines the frequency and type of published research in the 10 years that followed the changes to IDEA. Results indicate that further research is warranted, particularly in the areas of procedural integrity and full model implementation.
