THIS WAS DONE RATHER THAN AN EVALUATION OF CASE DISPOSITIONS BECAUSE NOT ENOUGH INFORMATION IS AVAILABLE ABOUT THE FINAL DISPOSITION OF CASES TO MAKE THAT TYPE OF ANALYSIS POSSIBLE. THE MAJOR DATA SOURCES USED IN THIS EVALUATION WERE: 1) INFORMATION FROM THE CASE FILES OF THE EXCHANGE; 2) QUESTIONNAIRES MAILED TO THE CHIEFS AND SHERIFFS OF MEMBER AGENCIES; 3) QUESTIONNAIRES DISTRIBUTED TO EXCHANGE OFFICERS; AND 4) INTERVIEWS WITH THE EXCHANGE'S DIRECTOR AND THE MEMBERS OF THE BOARD OF DIRECTORS. THE REMAINDER OF THIS REPORT PROVIDES A PROGRAM DESCRIPTION, A DESCRIPTION OF CASES, ANALYSIS OF THE ATTITUDES OF MEMBER AGENCY AND EXCHANGE OFFICERS, AND CONCLUSIONS AND RECOMMENDATIONS FOR THE PROGRAM.
