The purpose of the Delaware Performance Appraisal System is to assess instructional performance of teachers so that the quality of instruction can be improved, professional development activities can be prescribed, and a foundation for administrative decisions can be developed. The procedures outlined in this publication are the minimum standards for fulfilling the requirements of the appraisal system. Appraisal requirements vary slightly in that non-tenured staff is assessed annually while tenured staff assessment takes place on a two-year cycle. Forms used in completing the assessment are included with the outline of procedures. (JD)
