THE SELECTION OF ANY INDEX AS A STANDARD OF EFFECTIVE COUNSELOR PERFORMANCE INVOLVES A JUDGMENT ABOUT WHAT A GOOD COUNSELOR DOES. HOWEVER, INDIVIDUALS OR GROUPS WHO USE DIFFERENT PREMISES TO DECIDE WHAT IS RELEVANT TO SUCCESS MAKE IT DIFFICULT TO DETERMINE WHETHER SPECIFIC PROCEDURES OR PRACTICES ARE ASSOCIATED WITH DESIRABLE COUNSELOR BEHAVIOR. FOR THIS REASON, A COMPARISON OF PERCEPTIONS HELD BY SELECTED REHABILITATION GROUPS (COUNSELORS, DISTRICT SUPERVISORS, AND ADMINISTRATORS) TOWARD COUNSELING BEHAVIOR WAS CONDUCTED USING A SPECIALLY DESIGNED INVENTORY, THE CRITICAL BEHAVIOR SCALES INVENTORY. AS EXPECTED, REHABILITATION COUNSELOR EDUCATORS WERE MOST DIFFERENT FROM STATE AGENCY REHABILITATION PERSONNEL. STATE AGENCY PERSONNEL APPEARED TO VALUE ACTIVE COUNSELOR BEHAVIOR MORE THAN EDUCATORS. HOWEVER, THE PREDICTED SIMILARITY BETWEEN EDUCATORS AND TRAINED COUNSELORS IN STATE AGENCIES AND OTHER SETTINGS DID NOT MATERIALIZE. DIFFERENCES BETWEEN GROUPS ARE DISCUSSED WITH RESPECT TO POSSIBLE ENVIRONMENTAL AND GROUP INFLUENCES. SOME IMPLICATIONS FOR COMMUNICATION BETWEEN GROUPS AND TRAINING PROGRAMS FOR REHABILITATION COUNSELORS ARE ALSO PRESENTED.
