Measures of Collective Performance
Measures of Collective Performance: the use of measures required by the federal Elementary and Secondary Education Act and/or other standardized assessments used to measure the performance of groups of teachers. Measures of collective performance may assess the performance of the school, grade level, instructional department, teams or other groups of teachers. These measures can take a variety of forms including school-wide student growth measures, team-based collaborative achievement projects, and shared value-added scores for co-teaching situations.
In its first year of implementation, the school wide value-added score is being used for the 35 percent of teacher evaluations required to be measures of student learning growth for teachers of non-tested grades and subjects (NTGS). Tennessee is continuing to investigate what other measures can be used for adaptation as student learning growth methods.
In addition, another part of the Tennessee statewide evaluation system—15 percent of an educator’s rating—is based on measures selected by the teacher and the evaluator. This is in addition to the 35 percent that must be the individual’s value-added score for educators in tested subjects/grades and the school-wide value-added score for educators in non-tested subjects/grades. Through TEAC with its educator members, the state identified a set of measures for all categories of educators that could be used for the 15 percent, all of which are included in this PDF.
