Question is whether to focus on job-specific criteria or broader competencies and fit indices.
Traditional criteria include performance dimensions as rated in performance appraisals, production measures, records of past employment, etc. Nontraditional criteria may include personality variables, commitment, citizenship behaviors, satisfaction, etc. Reduces the pool but those left behind have better picture of job and organization as it really is and may enhance retention. Focus is on the quality of the measure. Requires an accumulation of evidence.
