Abstract
This article outlines a new, 3-pronged training model that has supported changes in practice (ie, attitudes, concepts, and skills). A large-scale, national training program designed this model to promote the inclusion of infants and toddlers in natural environments. The theoretical and empirical base for each of the elements in the model is discussed and is followed by the specific training strategies that were drawn from each literature base. The authors outline a package of training elements that may be utilized in in-service training programs for diverse groups of early interventionists, early childhood providers, and family members.
