This document summarizes a study examining the roles and responsibilities of school-based "mediating teachers" who support K-12 students enrolled in online courses through the Centre for Distance Learning and Innovation (CDLI) in Newfoundland and Labrador, Canada. The study found that mediating teachers spend a significant amount of time on administrative tasks like monitoring student progress, recording grades, and troubleshooting technical issues. They have infrequent contact with online teachers and rarely access course management systems. The roles and time commitments of mediating teachers have not changed significantly since the CDLI pilot program began. Further research is needed to better understand the time demands on mediating teachers.
