Purpose: The purpose of the research was to develop a competency-based performance appraisal resource for evaluating school nutrition (SN) managers and assistants/technicians. Methods: A two-phased process was used to develop the competency-based performance appraisal resource for SN managers and assistants/technicians. In Phase I, draft performance appraisal forms and an accompanying guide were developed based on structured interview responses from expert panels of SN directors and managers, competencies for effective SN professionals identified in previous research, and sample forms submitted by SN professionals. After expert panel review, Phase II involved a panel of SN professionals and state agency personnel in a directed review in which standard evaluative questions guided panel members in assessing the documents for clarity and relevance to SN job functions. Results: Results indicated that effective performance appraisal forms should have (1) criteria clearly defining expected performance, (2) a rating scale appropriately reflecting criteria, (3) clear instructions, (4) a user-friendly format, (5) space for comments, and (6) a plan for improvement. An accompanying guide should include basic information on the performance appraisal process. Assessment by expert and review panels ensured that the performance appraisal forms developed in this study were tailored to the specific competencies identified by research as fundamental to the job responsibilities of SN managers and assistants/technicians. Reviewers indicated that the guide contained appropriate information that it is useful and comprehensible to SN practitioners at all levels of responsibility and experience. Applications to Child Nutrition Professionals: The competency-based performance appraisal resource provides a universal platform for evaluation relevant to SN programs across the nation. It may be used for individual learning, employee training and orientation, and as a general reference for SN staff. The performance appraisal forms may be used to evaluate current performance, develop improvement goals for SN managers and assistants/technicians, assist with developing or modifying existing appraisal forms, and augment district-mandated forms to focus appraisal more closely on SN activities.
