The purpose of this basic narrative qualitative study was to explore how teacher teams in Blue Ribbon elementary schools, teacher teams in performing elementary schools, teams in businesses on the Inc. 5000 Fastest-Growing Private Companies in America list, and business teams not on the Inc. 5000 Fastest-Growing Private Companies in America list discuss the use of the eight mutual learning behaviors in their teams. Based on the eight mutual learning behaviors of effective teams theory by Roger Schwarz(2013), this study sought to understand how the eight mutual learning were behaviors exhibited by teacher teams in Blue Ribbon elementary schools, teacher teams in performing elementary schools, teams in businesses on the 2023 Inc. 5000 Fastest-Growing Private Companies in America's list, and business teams not on the Inc. 5000 Fastest-Growing Private Companies list.
