This training guide is prepared primarily for the professional practitioner; however, academicians may find the guide to have considerable value in both graduate and undergraduate courses in the helping services. The material presents techniques and methods for communicating test results of a psychometric nature, suggested standards for psychological evaluations, relationship to vocational decision making, and a synopsis of commonly used psychological tests with a brief, relevant bibliography. The discussion focuses on practical areas which should be relevant for all helpers, particularly psychometrists, rehabilitation counselors, social service workers, beginning psychologists, and some para-professional workers having some responsibility for using psychological testing and interpretation.
