Project RETAIN (Retention in Education Technical Assistance and Information Network) is a Florida project to assist school districts through identification and dissemination of effective practices that keep students with mild disabilities in school. One part of the project attempted to establish a consensus among experts in the fields of transition, special education, and dropout prevention on effective practices with this population. A three-round Delphi procedure was used to elicit the opinions of 10 national experts in four domains--organizational, programming, personnel, and social. A total of 180 effective practices were identified and grouped into 10 thematic areas. Panelists were also asked to rank the feasibility of identified practices. The experts agreed that good programs to prevent students with mild disabilities from dropping out should be realistic, student-centered, and flexible; provide wrap-around services; set limitations for which students and personnel are accountable; tie into real world demands; offer a place where students feel they belong and are wanted; encourage professional development; provide supportive administrators; foster intra-and interagency collaboration and cooperation; and view students holistically. Low feasibility ratings were given to practices considered valid but which involved major changes in belief systems or school systems. (Contains 27 references.) (DB)
