The Academy focuses on a high rate of interrater reliability using the required performance evaluation ratings. Using case studies, the participants will collect evidence and use the Illinois Standards for Principal Evaluation to rate the principals. Participants will use data collected from the case studies and compare the data to best practices for evaluating principals and assistant principals. This data will also be analyzed to prepare administrative and school-level professional development plans. Participants will prepare targeted professional development, in a collaborative and supportive way, plans that consider past results and contribute to professional and personal growth. This plan will be aligned to the school improvement plan. The instructional environment indicators will be analyzed. The purpose of the evaluation plan will be to communicate the outcomes and findings in such a manner that the principals and assistant principals set goals for improvement. The participants own personal bias will be analyzed while making these decisions.
