We should no longer be wondering if we should have performance appraisal, rather we should be researching the elements necessary for it to be successfully implemented and to ensure that we receive maximum benefits for improved learning for our students. Performance appraisal can be defined as "a positive, systematic, individualized due process evaluation program that can be applied to all members of the school organization. It is based on the assumption that people want to do a good job. It puts responsibility on both appraiser and appraisee to reach mutually agreed-upon objectives. The benefits are improved instruction for students, changes in practitioner behavior, enhanced commitment and communication." Performance appraisal is based on objective data rather than on personality and other factors. The experience of the Hyde Park (New York) school district in using this program has been positive but not without its problems. (Author/IRT)
