Although assessment use is a professional activity recognized by every major counseling organization, little is known about which assessments are used in counseling. In this study, 926 respondents from a random national sample of counselors reported their use of personality, projective, career, intelligence/cognitive, educational/achievement, clinical/behavioral, and environmental/interpersonal tests. Test rankings by frequency of use and comparisons by type of counselor and type of test are reported. Implications for policy and practice are discussed.
