This instructional module describes a performance assessment designed to equip prospective principals with the knowledge and skill needed to evaluate curriculum, observe and assess instruction, interact meaningfully with teachers about instructional decision-making, and design professional learning opportunities that enhance student learning outcomes. This project is conceptually grounded by Stein & Nelson's (2003) construct of "leadership content knowledge," which argues that effective leadership for instruction demands complex understandings of subject matter, how children learn that subject matter, and how teachers learn to teach that subject matter.
