Faculty & Staff

STEP faculty and instructors take primary responsibility for the design, delivery, and assessment of their courses. In addition to teaching, STEP faculty pursue a wide range of interests, including research practice partnerships at school sites.

STEP staff are an integral part of the STEP teaching and learning community, and one of the program’s great strengths. Their primary purpose is to follow candidate progress through the program and to facilitate success.
