This White Paper project was undertaken to address the Learning Disabilities Association of America (LDA) concerns regarding the Individuals with Disabilities Education Improvement Act (IDEIA) of 2004 statutory and regulatory requirements for the identification of Specific Learning Disabilities (SLD), and the subsequent U. S. Department of Education Final Regulations and Commentary regarding implementation of IDEIA (34 CFR Parts 300 and 301; Federal Register, 2006). The purpose of the White Paper is to provide additional information for and guidance to the federal government, professional organizations, practitioners, and the public. The LDA is hopeful that this document will facilitate legal, regulatory, policy, and training decisions, and ultimately, service delivery to children with SLD. This White Paper presents the expert professional opinions and empirical evidence regarding the identification of children with SLD and best practices in SLD service delivery. The preliminary findings of the LDA Expert Panel Survey and this White Paper represent the opinions and empirical evidence presented by 56 university professors and researchers, special education administrators, and special education lawyers with expertise in and public recognition for their work in SLD identification and intervention.
