RTI for SLD Application Process
Response to Intervention for the Determination of Specific Learning Disability Fidelity Tool
The Response to Intervention (RTI) for the Determination of Specific Learning Disability (SLD) Fidelity Tool, updated in October 2025, is available below in both Word and PDF versions linked on this page.
While the RTI for SLD Fidelity Tool has multiple purposes, it serves as a required component of an application process for local education agencies (LEAs) planning to implement RTI methodology for the determination of SLD. It is required to evaluate a LEA’s Multi-Tiered System of Support (MTSS) when using RTI methodology for the determination of SLD. The LEA must also include a Regional PaTTAN Consultant in their formal review for an initial application.
