A school district that locally develops and adopts its own educator appraisal system should have a clearly defined set of procedures for training appraisers. The school district should identify the qualities appraisers must demonstrate and include appropriate proficiency checks to evaluate the performance of all educators performing appraisals under the district's locally adopted appraisal systems. The school district shall be responsible for documenting that appraisers have met training criteria established by the district.
