This study addressed concerns of Pennsylvania legislators and government departments by examining coordination between education and other human service agencies in three program areas: early intervention (for preschool handicapped children); student assistance (for drug and alcohol abuse and other teenage problems); and teenage pregnancy and parenting. It sought to clarify the nature of the coordination problems that arose and the reasons for those problems in order to make recommendations about how to alleviate them in the future. Interagency conflict and service blockages were found to be independent problems for coordination. For teenage pregnancy, institutional survival concerns were the primary contributor to interagency conflict. The main cause of interagency conflict in student assistance was treatment philosophy and the main blockage to coordination was service capacity. For early intervention coordination, the main blockage was again service capacity. Conclusions and recommendations included: (1) coordination can increase the cost of services by increasing the demand; (2) coordination is facilitated by complementary interests; (3) arrangements that minimize competition between agencies should be established; (4) regulations contribute to coordination problems; (5) coordination is facilitated when programs have a clear purpose compatible with the philosophies of other involved parties; (6) local coordination councils can facilitate coordination; (7) planning and adjustment to facilitate coorddination must continue after new projects have started; and (8) increased resources are often needed to reduce service blockages.
