In the current research, we introduce the team CARE model for supporting team development during post-secondary education. Team CARE is part of a larger suite of assessments at itpmetrics.com. Team CARE is a free, online, survey-based assessment that allows team members to rate their team's health and functioning in four key categories (communicate, adapt, relate and educate), as well as provide written feedback about the team's functioning to add nuance and supplemental context to the numeric scores. Team members completing the assessment receive a report documenting their team's scores on the variables measured. We report on data from student learning teams suggesting that the variables in the team CARE model are reliable, and that they are correlated with team performance outcomes. Students' perceptions of the tool were also examined, and the findings suggest that team CARE is perceived to be valuable, useful and easy to use. Recommendations for practice are detailed, including sample assessment schedules for teams with differing life spans. Implications for future research and implementation are discussed.
