Project DEBT (Developmental Education Birth through Two), an early identification and intervention program for handicapped and at risk children and their parents, is described. The Koontz Child Developmental Program, the core curriculum for instructional planning and intervention in DEBT, is reviewed, and new data are presented. It is explained that the Koontz Program is used to formulate long term goals, weekly objectives, and instructional activities. Three sources of data are examined in a study of DEBT's effectiveness with handicapped children: Koontz scores, developmental rates, and followup placement after graduation from DEBT. Parent involvement data and evidence of DEBT's relationship with the community human service delivery system are also evaluated. Results are said to indicate that DEBT's interventions were effective and successful. (Author/CL)
