A quality control review of Connecticut's Sustained Effects studies was undertaken by the Chapter 1 Evaluation Technical Assistance Center (TAC) operated by RMC Research Corporation. Nineteen Connecticut school districts had selected from among four basic evaluation designs in implementing the Chapter 1 Sustained Effects requirement during 1982 to 1985. These designs enabled districts to examine the long-term effects of their Chapter 1 programs on: (1) summer drop-off students; (2) continuing students; (3) exiting students; and (4) continuing versus exiting students. The review identified the following minor areas for improvement in future Sustained Effects studies: evaluation design; test administration; and analysis of appropriate test scores. Most of the studies were of adequate technical quality and appeared to be useful. Areas of major significance in which improvement was needed were: (1) framing evaluation questions; (2) data analysis and interpretation; and (3) development of action plans for program implementation. Solutions to these problems are recommended. (SLD)
