Florida Center for Reading Research
The Florida Center for Reading Research (FCRR) was established to conduct research on literacy development and reading instruction and assessment.  Resources provided on the website are research based and range in target age from PreK through 12th Grade.  While the site does not specifically address RtI as a conceptual model, it does provide an array of evidence-based interventions that can be used in a data based, decision-making model such as RtI. Information regarding core and supplemental reading instruction strategies and progress monitoring tools is also included.
High School Tiered Interventions Initiative: Progress Monitoring
The High School Tiered Interventions Initiative (HSTII) is a collaborative effort among the National Center on Response to Intervention, the National High School Center, and the Center on Instruction that explores how RTI and tiered interventions are being implemented at the high school level. During this webinar, Dr. Kristen McMaster provided an overview of Curriculum-Based Measurement (CBM), including the purpose, a brief description of research, and a demonstration of how CBM data can be used to monitor student progress.
International Reading Association
This site offers a plethora of articles that have been collected by the International Reading Association (IRA).  Most of the resources listed on this site are published in professional, refereed journals and are available at no charge.  While the focus of the site is primarily on research in the field of reading and emergent literacy, there are some references included that address RtI and problem solving in more general terms.
Positive Behavioral Interventions and Supports
The OSEP Technical Assistance Center for Positive Behavioral Interventions and Supports was established by the Office of Special Education Programs, US Department of Education, to give schools capacity-building information and technical assistance for identifying, adapting, and sustaining effective school-wide disciplinary practices. The site provides examples of positive behavior supports (PBS: MTSS) across a tiered model with authentic data from schools and districts that have implemented PBS: MTSS.  Information for families is also provided.
