Graduate Teaching Assistantships

Graduate Teaching Assistants (GTAs) make an important contribution to the quality of undergraduate education at Western University. GTAs inspire, encourage, and guide students who embark on a learning journey in hundreds of programs in our 11 Faculties across campus.

A GTA may:

  • proctor exams
  • conduct field trips
  • work with students in lectures and tutorials
  • prepare materials or set-up required displays or apparatus for classes, tutorials and laboratories
  • grade essays, assignments, laboratory reports, tutorials and term tests
  • answer students’ questions through meetings or office hours

A GTA acts as a resource and a mentor to students as they grapple with theories in all disciplines.  A GTA works directly with students as they try to decide how they will use their new knowledge after they graduate.

GTA Training Programs

Lead TA

The Lead TA program is a new initiative on campus to facilitate the professional development of teaching assistants at a discipline-specific level. Sponsored by the School of Graduate and Postdoctoral Studies (SGPS), in collaboration with several Faculties on campus, it provides outstanding graduate students with an opportunity to apply their interest, teaching experience, and training beyond traditional TA duties.

During this pilot year, the program will position Lead TAs in 8 departments across campus where they will develop discipline focused TA training activities. By facilitating workshops, developing resources, and offering peer feedback through classroom observations, Lead TAs will serve as mentors, coaches, and liaisons for TAs in their home department.

This initiative to improve the teaching effectiveness of TAs at a departmental level complements the general, interdisciplinary TA training offered by the Teaching Support Centre (TSC).  In order to support the Lead TAs in their own professional development during the year, the TSC will provide ongoing training and resources to the group on facilitation, peer mentoring and teaching excellence.

The Lead TA pilot program is a result of collaboration between the SGPS, the Faculties, the GTA Union and the TSC.  If you would like to learn more about the program, please contact Mihaela Harmos.
