National Institute for School Leadership (NISL)
School Leadership

As of March 2021, no studies of National Institute for School Leadership (NISL) were found that fell within the scope of the School Leadership Review Protocol and met WWC evidence standards. Therefore, the WWC is unable to draw any conclusions about the effectiveness of National Institute for School Leadership (NISL) to improve outcomes within the scope of this topic area review.

The NISL program (formerly the NISL Executive Development Program) is a professional development program that aims to develop effective, strategic school leaders focused on preparing schools to provide high-quality instruction in a supportive learning environment. NISL is organized around 12 two-day professional development course units that are offered over 12–15 months. Each unit offers tools and diagnostic instruments to assess participants’ leadership skills and school climates. As part of the program, school leaders learn how to apply NISL’s instructional coaching model with teachers in their schools. The coaching model is a formal process in which school leaders work with teachers over multiple cycles of coaching to improve teacher effectiveness. The model is designed to support teachers in core content areas like English language arts, mathematics, social studies, and science.
