This report describes the attitudes and perceptions of allied health personnel toward the efficacy and performance characteristics of school-based teams supporting children with developmental concerns. Sixty-three allied health personnel were asked to complete the Attitudes About Teamwork Survey, the Team Characteristics Survey, and the Team Process Perception Survey. Respondents held a generally positive attitude about teamwork. Respondents' beliefs about the efficacy of the team process were moderately associated with critical performance characteristics. Effect sizes associated with these data suggest that the results were not only statistically significant but also noteworthy. Respondents also provided their perspectives on the benefits, limitations, supports, and recommendations of teamwork. Results were consistent with both the general teamwork literature and that focused on allied health professions. The authors describe practical implications of the results and directions for further investigation on this topic.
