In Monday’s post, I went through the DC teacher evaluation system, IMPACT, which weights value-added improvements in student scores at 50 percent of the teacher’s evaluation, with the remaining half of the evaluation covering 22 areas (fit into 9 categories). Five classroom observations are held,
three times by a building administrator and twice by an outside “master evaluator” who is a subject-matter expert and does not report to the building administrator.
Teachers in tested subjects are evaluated by standards different from those used for paraprofessionals, counselors, special education teachers and others in the system, with teachers in non-tested subjects having only 10 percent of their evaluation based on student scores.
