Educators rely on teamwork skills to productively contribute to professional responsibilities such as curriculum committees, professional learning communities (PLCs), co-teaching, and individualized education plan (IEP) teams. This quantitative study was designed to assess teacher candidates' knowledge, skills, and abilities (KSAs) related to teamwork. The instrument used in this study, Teamwork-KSA, measures an individual's KSAs in specific teamwork characteristics, and researchers looked for differences between teacher candidates' progression through an educator preparation provider (EPP) and Teamwork-KSA results. Statistical analysis was conducted using a Pearson's correlation, resulting in the finding that a relationship exists between GPA and Teamwork-KSAs. A statistically significant relationship was revealed between GPA and the following teamwork characteristics measured by Teamwork-KSA: "goal-setting and performance management," "planning and task coordination," and "self-management."
