Grading a stack of papers, leading a discussion section or lab, proctoring an exam, and holding office hours to tutor students, all in the same week, is a normal course load for a teaching assistant. The role is typically filled by students currently enrolled in a master's or PhD program in the subject they teach, so it's combined with their own coursework and research rather than pursued as a standalone job. It's often a first step toward an academic teaching career, giving early exposure to curriculum design and classroom management before moving into a faculty role.
Pros
Standard, predictable hours (30-40 a week) that fit around graduate coursework
Faster than average projected job growth (3.1%) keeps positions available
Builds direct teaching experience, valuable for anyone pursuing an academic career
Cons
Entry-level pay is quite low, since the role is structured as a graduate stipend rather than a full salary
The position only exists while you're enrolled in a graduate program, not a standalone long-term career
Balancing grading, leading sections, and tutoring alongside your own coursework and research can be demanding
A typical day
The morning starts with a 9am discussion section: thirty undergrads, one whiteboard, and the job of making Tuesday's lecture actually make sense. Office hours follow, where the same integral gets explained four different ways to four different students until it lands. The afternoon belongs to the TA's own coursework and research, because teaching is the side of the deal that pays tuition. The evening ends with a grading stack and a rubric, applied consistently from the first exam to the eightieth.
