Most graduate departments/programs engage several graduate students each year to assist in undergraduate teaching, tutorial work, and laboratory demonstrating, as Teaching Assistants (TAs).
At Queen’s University, TAs are unionized members of the Public Service Alliance of Canada (PSAC). The collective agreement is posted on the Human Resources website
The Centre for Teaching and Learning offers workshops, programs and services for TAs at Queen's. Complete details may be found on the website: http://www.queensu.ca/ctl/
