This "Stated Briefly" report is a companion piece that summarizes the results of another report of the same name. REL Northeast and Islands, in collaboration with the Northeast Educator Effectiveness Research Alliance and the New Hampshire Department of Education conducted a study of the implementation of new teacher evaluation systems in New Hampshire's School Improvement Grant schools. While the basic system features are similar across district plans, the specifics of these features vary considerably by district. Further, district fidelity to the plans, as measured by the exposure of teachers to different features of the evaluation system, ranged from moderate to high. Finally, researchers identified several factors related to implementation: (1) capacity of administrators to conduct evaluations; (2) initial and on-going evaluator training; (3) the introduction and design of student learning objectives; (4) the professional climate of schools, including the support of the new system by teachers and evaluators.
