Offering a discussion for administrators and practitioners serving disabled and at-risk infants, toddlers, and their families, these three addresses explore issues, strategies, and models of program evaluation. "Major Issues in Program Evaluation," by Kathryn Barnard, discusses the purpose of, process of, and ways of doing program evaluation, as well as the development of a model relevant to a wide range of early intervention programs. "Evaluation Strategies," by Victoria Seitz, gives three evaluation strategies: (1) process evaluation, which describes a project's client population and activities; (2) outcome evaluation, which tries to ascertain whether people are different as a result of receiving service; and (3) action research, which explores the mechanisms by which a successful intervention program helps those for whom it does work. Seitz also explores a variety of innovative research designs with which to evaluate intervention outcomes. "The Infant-Parent Program at San Francisco General Hospital," by Jeree Pawl, relates the process by which staff of a service program for young children and families worked together to design and implement an evaluation process which helped to improve clinical practice and supervision while simultaneously demonstrating the efficacy of the program to funding sources. The report also summarizes discussion elaborating themes raised by the three major speakers and relates program evaluation issues to current concerns of state administrators and community practitioners.
