Marking: A survey of Western University TAs revealed that 100% of TAs will mark at some point in their university careers. Marking can be daunting but preparation and endurance can get you through

  • Award winning Western TAs offer some advice for marking:

Marking-only TAs: Marking-only TAs do not have any duties besides marking tests and assignments. These types of TAships are most common for the large introductory courses. TAs may or may not hold office hours. Here are some words of advice from previous marking-only TAs (video LINK)

Lab TAs: TAing a laboratory course whether in the sciences, engineering, mathematics, computer sciences or even social sciences can be a challenging and rewarding teaching experience. Lab TAs primary responsibilities are in laboratories, providing pre-lab talks and assisting students in-lab with experiments or assignments.

TAs with Tutorials/Leading Discussions: As a TA in any number of faculties you may find yourself in the role of a tutorial or discussion facilitator. Tutorials are often assignment driven and are an opportunity for students to ask questions and attempt problems they were not able to in larger lecture sections. Discussion classes are usually associated with arts and humanities, social sciences and education lecture courses with heavy reading. Discussion classes are also an opportunity for students to ask questions and discuss both about lecture topics and course readings.

Online TAs

  • Ask if you can contribute test questions or assignment ideas Ask the course instructor to sit in and give feedback
  • Join the mentor program
