In each year of my PhD, I have applied for all the summer teaching assistant (TA) positions offered in the Department of Political Science (and, after second year, in the School of the Environment too). I never heard anything back as the result of my applications, including for frequently-advertised ’emergency’ positions and jobs in statistics courses which I expected to be less popular.
Today I had a brief conversation with a prof who I worked for in a fall and winter term and learned that virtually all summer TA jobs go to people who are beyond the 5-6 year span where U of T provides funding. Apparently, summer TA jobs all go to people who are in their 8th or 9th year, or otherwise well beyond the “funded cohort” and seniority is the overwhelming criterion used to select them.
It’s reflective of how U of T generally under-funds its graduate students, as well as how the quality of teaching provided to undergrads is clearly not a university priority.
