The Toronto Early Identification and Developmental Program (E.I.D.P.) has three main aspects: (1) the screening of kindergarten and first grade children in terms of potential learning difficulties; (2) service to the child and family together with supportive help to the school staff; and (3) research in connection with screening instruments. The introduction, in which the rationale and purpose of the program are discussed, is followed by the service manual which contains a model of the process of screening and service developed through the E.I.D.P. The practical information needed to implement an early identification program may be found in the manual. The two-part research section is composed of reports of studies involving various groups of schools. The Forest Hill report provides a description of the screening process which preceded the main E.I.D.P. The central portion of the research report is a description of the predictive tests and interviews used in selecting high risk children and includes a discussion of the major screening packages in terms of reliability and validity. The bibliography contains a list of tests as well as reference sources. Appendixes include instructions for administering and scoring screening tests and samples of interview forms and letters. (SDH)
