"The Educator’s Diagnostic Manual of Disabilities and Disorders (EDM) provides an excellent 'snapshot' of each of the disability categories, benefiting special education novices and experts alike. The information is detailed and presented in a user-friendly format. Each disability’s impact on a student’s education is clearly presented, and the segments that detail how to address each exceptionality in a student’s Individualized Education Program (IEP) provide an excellent 'how to' approach when planning to address the student’s documented educational needs. The EDM’s coding system provides a consistent manner to document each disability category, which offers clarity for the reader when creating and/or reading an IEP."--John B. W.
