The National Joint Committee on Learning Disabilities (NJCLD) is a national committee representing 11 organizations concerned about individuals with learning disabilities. The NJCLD considers and discusses contemporary issues in learning disabilities and develops and disseminates reports and statements related to these issues to influence policy and practice. The purpose of this NJCLD report is to examine the concepts, potential benefits, practical issues, and unanswered questions associated with responsiveness to intervention (RTI) and learning disabilities (LD). After brief overview of the approach, issues related to RTI implementation, including use as an eligibility mechanism, parent participation, structure and components, professional roles and competencies, and needed research, are addressed. The report is neither a position paper nor a "how-to guide" for implementing an RTI approach. (Contains a list of 9 resources and 4 notes.)
