Teaching Assistantship Interview Questions and How to Prepare

Teaching assistantship interview questions tend to focus less on what you know and more on how you’d help other people learn it. Not every department interviews TA candidates; some assign positions as part of admission. When there is an interview, it’s usually a conversation about teaching, fairness and reliability, sometimes with a short teaching demonstration.

This article covers preparing for that conversation. For what TA roles involve and how to evaluate an offer, see our pillar on teaching assistantships.

What interviewers are usually looking for

• Subject knowledge at the level of the course you’d support.
• Clear explanation, especially of basic ideas you may take for granted.
• Fairness and judgment in situations involving grades, academic integrity and student needs.
• Reliability and time management, alongside your own studies.
• Willingness to learn how to teach, since few new TAs have formal training.

Common questions, and what they’re testing

These are common examples, not questions from any particular university.

Common TA interview questions

Common TA interview questions

Question	What it is really testing	How to prepare
Why do you want to be a TA?	Motivation beyond funding	One honest reason connected to teaching or learning
Explain [a basic concept] as if to a first-year student.	Clarity and ability to simplify accurately	Practice two or three core concepts aloud, with an everyday example
A student says their grade is unfair. What do you do?	Fairness, following policy and knowing when to involve the instructor	Describe listening, checking against the rubric and escalating appropriately
You suspect a student copied an assignment. What do you do?	Understanding of academic integrity processes	Say you would follow the course and institution policy and report to the instructor, not confront the student alone
How will you balance TA duties with your own work?	Realism and time management	A concrete approach, such as fixed grading blocks each week
Tell us about a time you helped someone understand something.	Relevant experience, even informal	A short, true example from tutoring, lab partners, a job or a club

Answering with examples

For questions about experience, a simple structure helps: the situation, what you did, and the result or what you learned. Keep it to about a minute.

A fictional sample answer, for teaching only. Use your own true experience, not this one.

“In my undergraduate physics lab, my partner kept getting stuck on converting units. Instead of doing the conversions for them, I suggested we write the units next to every number and cancel them step by step. By the end of the semester they were checking my work. It taught me that a small, repeatable method often helps more than a full explanation.”

Why it works: it’s specific, the speaker’s role is clear and honest, and it ends with a lesson about teaching rather than a claim about being a great teacher.

If there’s a teaching demonstration

Some departments ask you to teach a short topic. Choose something basic and well defined, open with a question or quick example, check understanding partway through, and finish on time. Clarity matters more than covering a lot.

Questions to ask them

• Which course would I support, and what would a typical week involve?
• How many hours per week should I expect, and when are the busiest periods?
• What training or orientation do new TAs receive?
• Who do I go to with questions about grading or student issues?

Preparation checklist

• Re-read the description of the TA role and the course, if it’s named
• Prepare three short, true examples: helping someone learn, handling a difficult situation, managing your time
• Practice explaining two basic concepts aloud
• Know where to find the institution’s academic integrity policy
• Prepare two or three questions for the interviewers

The TA interview prep sheet gives you space to draft each of these.

A practical next step

Pick one basic concept from the course you’d most likely support. Explain it aloud, in under two minutes, to a friend or to your phone’s recorder. Listen back and note one place where the explanation could be clearer.
