THE WORKSHOP WAS DEVELOPED TO PRESENT TO SOCIAL WORKERS THE IDEAS AND FINDINGS FROM AN INTERAGENCY COLLABORATION PROJECT CONDUCTED IN VIRGINIA. THE WORKSHOP, WHICH INVOLVES PARTICIPANTS IN AN INTERACTIVE LEARNING PROCESS THAT INCLUDES DISCUSSIONS AND A SIMULATION EXERCISE, HAS FOUR GOALS: DEVELOPMENT OF AN APPRECIATION FOR COLLABORATION AND ITS EFFECTS; PROVISION OF INTRODUCTORY SKILL TRAINING IN COLLABORATION; IMPROVEMENT OF RELATIONS BETWEEN DRUG PROGRAMS AND PARTICIPATING AGENCIES; AND INVESTIGATION OF POSSIBILITIES FOR FUTURE WORK. THE WORKSHOP 'PACKAGE' IS IN THREE SECTIONS: ABSTRACTS OF THE INTERACTIVE WORKSHOP AND THE PROJECT ON WHICH IT IS BASED; OUTLINES TO GUIDE DISCUSSIONS AND PREPARATION FOR THE SIMULATION EXERCISE; AND MATERIALS FOR THE EXERCISE. THE AVAILABILITY OF A TABLE GAME FOR USE IN WORKSHOPS WITH FEWER THAN 10 PARTICIPANTS (THE MINIMUM REQUIRED FOR THE INTERACTIVE WORKSHOP) IS NOTED. (LKM)
