Research on program accountability led to the development of a management system that ensures that current research findings are immediately implemented to promote the progress of people in treatment. In 1993, almost two decades of research on organizational and administrative systems, accountability systems, staff training and mentoring, and program evaluation were summarized in an invited article for the twenty-fifth anniversary issue of the Journal of Applied Behavior Analysis (the premier journal of the field), which recognized the Princeton Child Development Institute as one of three "enduring programs" in applied behavior analysis. PCDI's work in developing, analyzing, and improving human service systems has also been recognized by the Senate of the State of New Jersey (commendation on research and service to persons with autism, 1988); by the National Teaching-Family Association (Outstanding Contributions Award, 1989); by the Norwegian Association for Behavior Analysis (featured interview in Diskriminanten, 1991); by Developmental Disabilities Services Managers (Annual Award for Outstanding Contributions in Management, 1992); by Division 25 of the American Psychological Association (first Fred S. Keller Award for Distinguished Contributions to Behavioral Education, 1994); and by the Association for Behavior Analysis (Award for Enduring Programmatic Contributions in Behavior Analysis, 1999).
