Evaluation and Program Planning is based on the principle that the techniques and methods of evaluation and planning transcend the boundaries of specific fields and that relevant contributions to these areas come from people representing many different positions, intellectual traditions, and interests. In order to further the development of evaluation and planning, we publish articles from the private and public sectors in a wide range of areas: organizational development and behavior, training, planning, human resource development, health and mental wellbeing, social services, corrections, substance abuse, and education. The primary goals of the journal are to assist evaluators and planners to improve the practice of their professions, to develop their skills and to improve their knowledge base.
