This report describes the background, program implementation, student development evaluation, and recommendations of SuperStart Plus, in New York City. SuperStart Plus, a comprehensive integrated prekindergarten program that serves general education and special education children in the same classroom, is designed to provide a developmentally appropriate learning environment to enhance the cognitive, social, physical, emotional, and language development of 3- and 4-year old children. The program included staff development and parent outreach services. In 1992-93, the program's first year, 337 general and special education students participated. The first section of the report presents the program's background and evaluation design, and the characteristics of participating students. The second section describes the program's implementation, dealing specifically with the classroom environment, instructional practices, continuity across grade levels, staff activities, parent involvement and family services, and staff perceptions of the program's strengths and challenges. The third section presents evaluation results indicating that both general education and special education students showed significant gains in motor, socio-emotional, language, and cognitive development. The general education students achieved greater gains than the special education students, but these results are presented with the caution that the evaluation instrument was not designed specifically for special education students. The general education students showed slightly lower gains in motor and language development than did students in the original SuperStart program, which did not include special education students. The fourth section provides recommendations from the Office of Educational Research to enhance effectiveness of administration, curriculum, staff development, and the parent component. A copy of the developmental profile used to evaluate participants in the SuperStart Plus program is included. (AP)
