The purpose of the investigation was to observe the relationship between the personality of high school counselors and their interpersonal characteristics. Forty high school counselors responded to the 16PF and 160 senior counselees rated their respective counselors by completing the Barrett-Lennard Relationship Inventory. Moderate relationships were observed. Counselors who were rated high by their counselees on interpersonal characteristics tended to be assertive, happy-go-lucky, venturesome, suspicious (hard to fool), and self-sufficient. Since Rogers (1957) and others include interpersonal characteristics as essential to effective human relations, counselors reaching higher levels of these significant factors tend to have greater success with constructive client outcomes.
