Lead a discussion section
After lecture, work a hard example, ask students to explain one step, and reteach what they miss.
Career profile
College Teaching Assistant
Teaching assistants lead discussions, check work and answer questions for college students in one course.
Some students can recite a formula but cannot say when it applies. Helping them spot that gap also tests whether teaching your field suits you.
A day in the life
Mark and record grades
If your role includes grading, mark papers, log the points and review a tricky one with the instructor.
Work one step in office hours
Sit with a student, review their attempt together, find where the logic breaks and work through that step.
Prepare for the next class
Make answer keys or visual aids and warn the instructor before students see a confusing assignment question.

Fit, tradeoffs & changing tools
You might like this if…
- You like hearing how someone reached an answer, including a wrong one.
- You can give careful feedback without making it personal.
- You are willing to have someone observe your teaching and suggest changes.
Things to weigh
- Teaching preparation and student questions compete with your own coursework and research.
- Reading many similar assignments takes concentration, and students may challenge a grade you helped decide.
Where AI may help
Generative artificial intelligence (AI), which produces text from prompts, can suggest ways to phrase feedback on common mistakes when course rules allow it.
What people still lead
You still check the explanation and connect feedback to the student's actual work. Sensitive student submissions need approved handling.
What we can’t predict yet
How much grading AI will take over remains unsettled. Accuracy, fairness, privacy, and campus rules limit which tasks can be handed off.
Pay in context
Earnings
Read an assistantship offer as both a paycheck and a set of appointment terms. Tuition support can matter alongside cash pay.
National midpoint
The 2025 median was $42,910 annually for postsecondary teaching assistants. Half earned more and half earned less; this is not a starting-pay promise. Hourly pay is not reported for this title.
The national spread
In May 2025, the 10th-percentile annual wage was $28,600 and the 90th-percentile wage was $76,420. These are wage percentiles, not starting and senior salaries.
Compare the whole appointment
Graduate stipend levels can differ by department. Tuition support and health insurance may depend on eligibility, so compare those benefits with the appointment's workload and dates.
Openings include replacement hiring
Employment is projected to grow 2.7% from 2025 to 2035, with about 25,700 openings annually. Openings include replacing workers, not just adding positions.
Getting started
Apply for a graduate assistantship
Paid
- What the route involves
- Enter graduate study and apply through a department. At North Carolina State University, eligibility includes full graduate standing, fall and spring enrollment, and a grade point average of at least 3.000.
- What it can lead to
- Selection brings a paid teaching appointment, such as leading a recitation or supporting a laboratory course.
- What to check
- Admission alone does not secure an appointment. International students must also meet applicable employment requirements.
Build toward an undergraduate teaching role
Paid
- What the route involves
- In Indiana University Bloomington chemistry, complete the teaching internship and earn at least a B in the course you want to assist. Meet its course qualifications, schedule needs, and training requirements, including lab safety for laboratory roles.
- What it can lead to
- You become eligible to apply for paid work helping with discussions, laboratories, or office hours while still an undergraduate.
- What to check
- These are department-specific requirements. Its undergraduate assistants do not assign grades or grade subjective work; positions depend on staffing needs.
You join a faculty member's course team. The instructor sets your responsibilities and which decisions you can make about grades, extensions, and student requests.
After entry
Career paths
This starts where the entry routes leave off: early work, growing capability, and advancement or specialization.
Get established
Review the syllabus and calendar with the instructor. Agree on grading expectations before the first stack of assignments arrives.
Improve your teaching
Have the instructor observe a section. Use the feedback to revise an explanation or activity that left students confused.
Coordinate other assistants
Where lead teaching assistant roles exist, you can help coordinate sections, organize grading, and support newer assistants.
Where you can work
Lecture courses with smaller sections
Your group works through difficult lecture material. Meetings with other assistants help keep sections coordinated.

Try it
See whether the job clicks before you commit to the path.
Choose a short introductory college reading or problem you understand. Run a ten-minute mock discussion with a friend: ask them to explain their reasoning, then adjust one explanation to address their question. Notice whether you enjoy that back-and-forth.
