The data reported here represent the major findings of a number of Institute for Research on Learning Disabilities (IRLD) research studies. The relevant research reports are listed in Appendix A. A summary of the findings is provided in Appendix B. These findings are summarized in two general areas: (a) information on contemporary assessment practices gathered from individual assessors, decision makers, or students; and (b) information gathered on the team decision-making process. The implications of the findings for school psychology are discussed, and reactions to the findings and implications are provided by a practicing school psychologist (Betty Yanowitz) and by an administrator at the state department level (John Taylor).
