We have extensive experience developing performance appraisal instruments.  We develop behaviorally-based performance appraisals that focus on observable behaviors by  conducting interviews and workshops with incumbents and supervisors.  During the workshops, we ask participants to identify behaviors that comprise performance at various levels (e.g., Needs Improvement, Meets Expectations, and Outstanding).  Our performance appraisal instruments can be administered electronically, using formula-embedded spreadsheets, to facilitate ease of use and to minimize computation errors.  Such instruments are useful for providing specific performance feedback as well as for administrative purposes.
