Responsiveness-to-Intervention Symposium

December 4-5, 2003 * Kansas City, Missouri

The National Research Center on Learning Disabilities sponsored this two-day symposium focusing on responsiveness-to-intervention (RTI) issues. The speakers, discussants, and participants assembled represented the wide diversity of individuals with a vested interest in LD determination issues. Advocates, instructional staff, researchers, and state-level education officials brought their collective and considerable expertise to the discussions.

Frank R. Vellutino of the University at Albany presented this invited paper during the symposium. For links to other papers and materials, visit the main Symposium 2003 page.
