Briefly described in this paper are the screening process and intervention strategies used by the Quincy, Massachusetts, public school system since 1977 to identify children at risk for school failure due to special needs. Mention is made of a current longitudinal follow-up study designed to assess the usefulness and accuracy of the risk categories in the screening process and the effectiveness of intervention strategies. The low incidence of high- and moderate-risk students is said to be due to two preschool programs: the Chapter 766 preschool program and the Title I Early Childhood Program. (RH)
