The IPA, with our partners in the School Leader Collaborative, developed the School Leader Evaluation Plan to assist school districts with the development of their own school leader evaluation systems that are relevant and useful. Unlike other evaluation tools that are comprised of checklists or only focus on activities that school leaders do, the School Leader Evaluation Plan seeks to assist school districts with the development of an evaluation system that helps school leaders grow their leadership dispositions and the skills necessary for them to do their work effectively throughout their career continuum from Aspiring to Launching to Building to Mastering.
