What does "high-impact" mean in extra-curricular experiences?

Abstract

This study, conducted by a small group in a master’s level class taught by Dr. Christine Wilson, assessed extracurricular experiences at a large, public university to identify potential alignment with characteristics of “high-impact practices” as defined by the Center for Postsecondary Education (2015). Students engaged in extracurricular experiences tentatively defined as high-impact were invited to participate via surveys and interviews. Results and findings indicated significant alignment, and two additional potential characteristics: a sense of belonging and purpose.
