Retaining Effective Teachers Policy
The state should ensure that teachers receive feedback about their performance and should require professional development to be based on needs identified through teacher evaluations.
Michigan requires that annual performance evaluations provide teachers with "timely and constructive feedback." In addition, the state requires that evaluations be used to inform relevant coaching, instructional support and professional development. Teachers rated minimally effective or ineffective are placed on an individual improvement plan developed by the school administrator or designee in consultation with the teacher. These improvement plans include "goals and training and [are] designed to assist the teacher to improve his or her effectiveness."

Michigan recognized the factual accuracy of this analysis.
Professional development should be connected to needs identified through teacher evaluations.
The goal of teacher evaluation systems should be not just to identify highly effective teachers and those who underperform but to help all teachers improve. Even highly effective teachers may have areas where they can continue to grow and develop their knowledge and skills. Rigorous evaluations should provide actionable feedback on teachers' strengths and weaknesses that can form the basis of professional development activities. Too often professional development is random rather than targeted to the identified needs of individual teachers. Failure to make the connection between evaluations and professional development squanders the likelihood that professional development will be meaningful.
Many states are only explicit about tying professional development plans to evaluation results if the evaluation results are bad. Good evaluations with meaningful feedback should be useful to all teachers, and if done right should help design professional development plans for all teachers—not just those who receive poor ratings.
Professional Development: Supporting Research
For evidence of the benefits of feedback from evaluation systems, and the potential for professional development surrounding that feedback, see T. Kane, E. Taylor, J. Tyler, and A. Wooten, "Evaluating Teacher Effectiveness." Education Next, Volume 11, No. 3, Summer 2011; E. Taylor and J. Tyler, "The Effect of Evaluation on Performance: Evidence from Longitudinal Student Achievement Data of Mid-Career Teachers," NBER Working Paper No. 16877, March 2011.
Much professional development, particularly those that are not aligned to specific feedback from teacher evaluations, has been found to be ineffective. For evidence see M. Garet, A. Wayne, F. Stancavage, J. Taylor, M. Eaton, K. Walters, M. Song, S. Brown, S. Hurlburt, P. Zhu, S. Sepanik, F. Doolittle, and E.
