School psychology is a very complex field further complicated by current socio-political contexts which mandate the development of a psychology of school psychology, requiring two things as first steps. The first step is a model which outlines the conceptual map of the area, gives direction to investigations in the area, and checks on the generalizability and usefulness of the findings. This 3S model combines systems theory, behavior setting theory, and specifics profiling. Concurrently with the development of the model, new methods need to be employed in the investigation of problems of school psychologists, such as systems analysis, behavior setting surveys, chronologs, and specifics profiling. Problem solving techniques can synthesize the models and methods into a practical working strategy. (Author)
