These materials are intended for use by those wishing to conduct a Training of Trainers (TOT) for the RTI Implementer Series. TOT facilitators should have knowledge of the materials provided here, the Implementer Series training module materials (e.g., PowerPoints, training manuals, and handouts), Facilitator's Guide, and related readings found on the Center's website, such as the Essential Components of RTI "A Closer Look at Response to Intervention." The three Implementer Series training modules are intended for beginning implementers of RTI and provide foundational knowledge about the essential components of RTI and to build an understanding about the importance of RTI implementation.
