Three main types of assistantships cover most funded graduate positions at US universities: Teaching Assistantships (TAs), Research Assistantships (RAs), and Administrative or General Assistantships (GAs). The type you secure determines your day-to-day responsibilities, funding structure, and the approach you need to take when applying.
Teaching Assistantship in the USA
A Teaching Assistantship (TA)places students alongside a professor to support undergraduate teaching. TAs are usually assigned through departmental applications, typically after completing the first semester, rather than by approaching individual professors directly.
Stipends vary widely by university, from around USD 15,000 (₹14.4 lakh) a year at institutions such as West Virginia University to upwards of USD 35,000 (₹33.5 lakh) a year at Cornell University. Some TA positions may also include full or near-full tuition support, depending on the university and programme.
Key Responsibilities of a Teaching Assistant:
- Leading Discussion Sections: Running smaller recitation groups that break down material from a professor's main lecture.
- Grading: Evaluating assignments, quizzes and exams against a rubric the professor sets.
- Lab Supervision: Overseeing undergraduate lab sessions and answering procedural questions during them.
- Office Hours: Holding scheduled hours to answer student questions outside class time.
Research Assistantship in the USA
A Research Assistantship (RA) assigns students to a specific professor's funded research project, where you work in their lab or office rather than in front of a classroom. The professor benefits from a reduced workload on active grants, while students gain direct research experience that frequently feeds into your own thesis or dissertation.
Where a TA's role centres on teaching, an RA's role centres on research, and RA stipends are funded out of the professor's grant rather than a general departmental teaching budget, which is why RA stipends are typically higher than TA stipends in well-funded labs.
Key Responsibilities of a Research Assistant
- Data Collection and Analysis: Gathering and processing data for the professor's funded project.
- Literature Review: Surveying existing research to frame the project's direction.
- Report Writing: Documenting findings for publication or for the funding body.
- Lab or Office Management: Maintaining equipment, records or the professor's research files.
RAs are typically secured by directly contacting a professor whose research aligns with your interests, often before or right after arriving on campus. Email the professor with a short note on why your background fits their current project, and attach your CV. A positive reply usually leads to an informal interview before any formal offer, so a professor already familiar with your work through this outreach has a far better chance of hiring you than one who first meets you through a generic application.
Administrative/General Graduate Assistantship in USA
A General or Administrative Graduate Assistantship places students outside the classroom or research lab entirely, supporting a university office instead. This is the assistantship route most likely to be open to students in programmes without a teaching or lab component.
- Typical Placements: Admissions offices, student affairs, career services, international student offices, and academic conference organisation.
- Compensation: Follows the same stipend-plus-tuition-remission structure as TA roles, since GAs are university employees under the same policy.
- Duties: Event coordination, outreach to prospective or current students, and administrative support for departmental projects.
- How to Apply: Through the specific office's own hiring process, which functions like a regular campus job posting rather than a departmental TA or RA application.
