National school counselor certification examinations and state credentialing standards require knowledge of and skill development in assessment (California Commission on Teacher Credentialing [CCTC], 2001; National Board for Certified Counselors, 1998). And, professional associations have specified assessment competencies (American School Counselor Association [ASCA] & Association for Assessment in Counseling [AAC], 1998; Drummond, 1992). School counselors in California were surveyed about their student assessment practices and their perceptions about the adequacy of their training. Results indicated that school counselors utilized some aspects of assessment more than others and rated their training in those areas as adequate or good. Implications for practice and recommendations for future research are presented.
