Recent efforts to assess complex human performances in various work settings are reviewed. The review is based upon recent psychological, educational, and industrial literature, and technical reports sponsored by the military services. A few selected military and industrial locations were also visited in order to learn about current research and development efforts related to personnel performance evaluation. Although this survey was concerned primarily with techniques for assessing the performance of trained practitioners, as opposed to aptitude testing, certain aptitude measurement procedures which could be applied to the post-training assessment of behavior were also included. Measurement techniques which are typically employed to assess trainees but could also be used to assess practitioners are also described. Techniques for assessing perceptual processes, communication or interpersonal skills, and psychomotor skills are included. The evaluation methods are classified under the headings: achievement and aptitude tests (multiple choice tests), self-provided information (interviews and self-appraisals), appraisal by others (rating and ranking techniques), behavioral measurement (situational proficiency tests), and record audit (medical or flight records audit). For each method, its reliability, validity, current state, feasibility, and sources of additional information are discussed. Its appropriateness for evaluation of physicians is also considered.
