This sixth-year (1986 through 1992) summative evaluation examines in depth the participant attributes, services provided, and longitudinal benefits of the Early Childhood Development programs in the Kansas City, Missouri, school district. The report contains the following: (1) profile of participants in the Parents as Teachers (PAT) and Early Learning Center (ELC) programs since implementation; (2) comparison between the PAT and the statewide Second Wave Study populations; and (3) longitudinal assessments of academic performance of former PAT and ELC students. Following a summary of major findings, the report describes the evaluation of the screening component of the program, which served 7,250 children. Next, evaluation of the Parents as Teachers program is described. The report then describes the Early Learning Center (ELC) program. The report concludes with tabulations of screenings, parent perceptions, PAT enrollment and characteristics, ELC teacher and parent perceptions, and ELC participant characteristics. ELC District locations and ELC child observation record variables are appended. (WP)
