Group Discussion Peer Leaders (GDPL) are veteran PLs that have been leading and/or supervising for a minimum of six semesters. These GDPLs are handpicked by the program staff, and are individuals that have expressed interest in this role, have been supervised directly by the staff, and exhibit excellent content knowledge and pedagogy skills. These GDPLs are also training at the beginning of the semester, and are also trained through different professional development workshops. The GDPLs assume the Learning Specialist role in the PLTL program. They conduct the weekly Group Discussions (GDs) to train the PLs.
