The offer letter says “around ten hours a week”. Weeks one to six, it is. In week seven, 120 midterm essays arrive at once, each needing fifteen minutes to read and comment on, plus sixty emails about grades. That week the doctoral student works thirty hours on the course and does not touch the thesis. It happens again in week twelve.
Teaching assistantships are genuinely valuable: you understand the subject more deeply, learn to explain, earn income and build evidence of teaching for later. They are also one of the most common reasons theses slow down. This article is about teaching well within the hours you are paid for.
Know exactly what kind of work you have taken on
| Task | Common time trap | How to stay within hours |
|---|---|---|
| Leading seminars or tutorials | Over-preparing, rereading the entire course reading | Use the lecturer’s materials and questions; prepare for the session plan, not the whole chapter |
| Supervising labs or practicals | Staying late to help slower groups | Announce the end time; direct slower groups to a shared help session |
| Marking | Writing long comments on every script | Time-box each script, use a comment bank |
| Answering student questions | Emails trickling in day and night | One channel, set response windows, a forum for repeated questions |
| Giving a lecture | Building slides from scratch | Ask for previous years’ slides and materials and adapt only what is needed |
At the start of term, ask the course leader two questions: which weeks marking falls in, and how much written feedback is expected. The answers tell you how to plan your thesis work around the peaks.
Marking quickly and fairly
- Study the rubric and any model answers before marking the first script. If the rubric is ambiguous, ask immediately rather than improvising.
- Mark five scripts, then stop. Send those marks and comments to the lecturer to calibrate. This avoids re-marking a hundred scripts because your standard drifted.
- Mark by question, not by script, for multi-question papers. Marking question one for the whole class before moving on makes you both faster and more consistent.
- Time-box each script and use a timer. If the budget is fifteen minutes, script thirty gets fifteen minutes too, not five because you are tired.
- Use an adapted comment bank. Write eight to ten comments for common issues in advance, then add one or two personal sentences per script.
- Mark in short batches. Ten to fifteen scripts at a time, take a break, then reread the first script of the batch to check you have not drifted.
Short feedback that helps
Students rarely read long paragraphs of feedback. A good comment usually has three parts: one specific strength, the single most important thing to fix, and a suggestion for how. For example: “Your comparison of the two models is clear and well supported. The main thing to improve is that your central argument only appears at the end; state it in the introduction so the reader knows what you are setting out to show.”
Boundaries with students
- State your contact channel and response time in the first session, for example replies to email within two working days.
- Redirect common questions to the course forum, so you answer once for everyone.
- Do not debate grades by message. Requests for re-marking follow the course procedure, usually via the course leader.
- Mind the small age gap. Many TAs are only a few years older than their students; keeping communication in official channels and on course matters protects both sides.
- Pass on issues beyond your role, such as mental health crises or suspected misconduct, to the lecturer and the university’s specialist services.
Track your real hours
For the first four weeks, log the actual time you spend on the course each day. If you consistently exceed your hours, take that log to the course leader. A concrete record is far more likely to lead to an adjustment than “I’m really busy”. Many universities also have rules on TA workloads; the graduate school or a graduate workers’ union, where one exists, is the place to ask.
In practice: protecting your thesis during marking season
- Start of term: mark marking weeks on your calendar; in those weeks, set small concrete thesis goals, such as revising one section, rather than drafting a new chapter.
- Keep one fixed thesis block every week, even at peak times, for example Monday morning before you open course email.
- Mark in the afternoons, keeping your sharpest morning hours for research.
- Warn your supervisor about peak weeks so meetings and draft deadlines fit around them.
Turn experience into evidence
At the end of each term, spend half an hour recording: which course, what level, how many students, what you were responsible for, what new activities or explanations you tried, and any feedback from students or staff. Save thank-you emails that mention specifics. When you write a teaching statement for job applications, you will have real examples instead of generalities.
If you are about to start a TA role, send the course leader a short email now asking about marking dates, feedback expectations and how students should contact you. Those three answers shape most of your term.
Câu hỏi thường gặp
What does a graduate teaching assistant do?
It depends on the institution and course: leading seminars or tutorials, supervising labs, marking, answering student questions and occasionally giving a lecture. Your contract or offer letter usually states the hours and duties.
Will being a TA slow down my PhD?
It can, mainly because actual hours often exceed the paid hours, especially during marking periods. Tracking your real hours for the first few weeks tells you when to raise it with the course leader.
How can I mark quickly but fairly?
Study the rubric, mark a few scripts and agree standards with the lecturer, mark question by question rather than script by script, time-box each script, and use a bank of standard comments adapted for each student.
Do I have to reply to student emails late at night?
No. Announce your contact channel and response time at the start, for example within two working days, and redirect common questions to the course forum so everyone sees the answer.
Does TA experience help with academic job applications?
Yes, if you record specifics: which course, how many students, what activities you designed, what feedback you received. Those notes become material for the teaching statement in your applications.
