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.
Colorado requires that teachers receive copies of their evaluations "at least two weeks before the last class day of the school year." The written evaluations are to be discussed by the teacher and the evaluator. All evaluations, regardless of rating, shall include "what improvements, if any, are needed in the performance of the licensed personnel and shall clearly set forth recommendations for improvements, including recommendations for additional education and training." The state also specifies that professional development activities be linked to a teacher's evaluation and performance standards. Remediation plans are developed for teachers who have been given a rating of less than effective.
Colorado Revised Statutes 22-9-105.5 3(b) and 22-9-106 Rules http://www.cde.state.co.us/sites/default/files/documents/educatoreffectiveness/downloads/rulemaking/1ccr301-87evaluationoflicensedpersonnel11.9.11.pdf
Colorado 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.
