From leading authorities, this indispensable work is now in a revised and expanded second edition, presenting state-of-the-art tools and procedures for practitioners. The book shows how to use response to intervention (RTI) to evaluate K-12 students for specific learning disabilities (SLD). The second edition gives increased attention to optimizing the instructional environment in the context of a multi-tiered system of supports (MTSS). Procedures are described for screening at-risk students; using RTI to intensify instruction in reading, writing, and math; identifying SLD; determining eligibility for special education; and planning individualized education programs. Case examples and pointers for practice are woven throughout. In a convenient large-size format, the book includes reproducible tools that can be downloaded and printed for repeated use.
