The Educator Evaluation Pilot Project Midyear Survey gathered teacher feedback about (a) how well various components of the new evaluation system are being implemented; (b) how much time, on average, is required to complete each component of the system; (c) how much each component contributes to professional growth; (d) perceptions and attitudes about the pilot; (e) the level and quality of support provided to teachers for the purpose of enabling them to participate in and implement the new system; and (f) the most beneficial and challenging aspects of the evaluation system. The Office of Research sent an e-mail message of survey invitation with a link to the online midyear survey on January 17th, 2012 to all teachers whose names and e-mail addresses appeared on lists vetted by their principals (n = 765). After the initial invitation, three e-mail survey reminders were sent, spaced approximately 10 days apart leading up to the final deadline (February 20th, 2012). A total of 421 teachers from all 25 pilot schools completed the survey. This is a response rate of 55%, which means there is 95% confidence (±3.2% margin of error) that the results of the survey are representative of the larger population. It is worth noting that feedback from participants is gathered at the halfway point of the first year implementation of the pilot project. Therefore, data from this interim evaluation report should be taken not to pass judgment on the merit of the system but rather to identify the strengths and weakness of the system during the early phases of implementation. The information should be used diagnostically as a "temperature check" to provide additional clarifications and support to schools participating in the pilot project. The feedback from the experiences of pilot schools could also be utilized to better inform the scaling-up process in coming years. With this caveat in mind, recommendations are provided.
