The monograph presents an analysis of screening programs for handicapped children in New York State school districts. An introductory section considers such factors as the general parameters of a screening program and characteristics of a good screening program. Major policy options for screening are seen to include decisions regarding universal or selective screening, use of screening tests of local origin, and examiners' competencies. Taxonomies for screening learning impediments are reviewed, along with a discussion of the variability of screening procedures and a listing and evaluation of instruments used in New York State. Suggestions are made for developing a public awareness program to be used in conjunction with the formal screening program. The final section provides overviews of 25 screening tests used in the state. (CL)
