The United States is in an era of high-stakes evaluation of educators (i.e., teachers and principals), the results of which are used to inform human capital decision making (i.e., recruitment, hiring, retention, and dismissal), which in turn impacts school capacity and student learning. The present article describes the School System Improvement (SSI) Project, a school-wide educator evaluation initiative that includes 22 high-poverty schools. The primary goal is to present the Year 1 planning for implementation of educator evaluation, highlighting the use of system consultation for planning. The SSI Project team includes researchers in school psychology and special education, school administrators, and teachers. The project aims to implement a multimethod educator evaluation system that generates scores for informing targeted, evidence-based professional development. Project goals are to increase educator competencies that lead to improved student achievement. Finally, directions for training and recommendations for future school reform are presented.
