To identify the aptitude profile of successful guidance counselors, tests were administered to 49 guidance counselors (14 male, 35 female) ranging in age from 29 to 62 (Mean age 42) and having an average of 9.5 years experience. The findings indicated that guidance counselors as a group scored near or above the Johnson O'Connor Research Foundation's population median on all tests in the Foundation's aptitude test battery. Counselors tended to have above-average Ideaphoria (the flow of their ideas was high) and Inductive Reasoning (they were quick to see relationships among separate facts). These abilities should allow counselors to diagnose problems, find various solutions, and communicate their ideas to others. In addition, counselors scored high on Foresight (the ability to focus on distant goals). This ability is useful in occupations requiring a great deal of training, such as guidance counseling; all but one counselor in this sample had earned a college degree, and 92% also had a graduate degree. Counselors were also above-average on Graphoria (suggesting that they do clerical tasks quickly and accurately), Silograms (suggesting good memory for words), and Finger Dexterity. The high scores on these last three aptitudes are more difficult to interpret. (Author/LPG)
