This report focuses on one method of human services integration--starting with a categorical funding and program base which is expanded to integrate complementary services and resources into a comprehensive service package. The four projects examined illustrate the following initial categorical bases: Community mental health services, primarily limited to counseling juveniles (East Central Kansas Mental Health Center); juvenile and family counseling in a community setting (Brooklyn Family Reception Center); traditional elementary and secondary education (Bethlehem Area Community Education Project); and employment evaluation and testing for the handicapped (Atlanta Rehabilitation Center). This report is divided into two major parts. Part I, Four Local Approaches, first presents the initial focus of each project. The reasons for initiation, how they were organized and funded, services provided, and the approach to program expansion are then discussed. Part I also describes the nature and evolution of the funding of each project in relation to the pace of growth. The experiences of the project developers in obtaining, maintaining, and expanding their financial bases are also described to provide insight into the role finances play in service integration. Part II, Four Case Studies, describes each project in depth. (The four projects were not selected based upon any set of criteria to ensure that they were typical or representative of service integration projects. Rather, they are four diverse examples of expansion from a single categorical program base.) Organizational flowcharts are included for each project. (SH)
