Indian Institute of Technology Bombay — PhD Admission Guide
Doctoral admission at IIT Bombay — process, categories and funding.
IIT Bombay admits PhD scholars across engineering, sciences, design, management (SJMSOM) and humanities. Applications are made to a department under a specific admission category — Teaching Assistantship (TA), Research Assistantship (RA), project positions, sponsored, and part-time — each with its own requirements.
Departments select through written tests and interviews centred on fundamentals and research aptitude. Alignment with faculty research areas matters: applications that name credible potential supervisors and directions fare better at shortlisting.
Eligibility
- Master's degree in a relevant discipline with first-class or the minimum specified marks/CGPA (category relaxations per norms).
- Bachelor's-degree candidates with exceptional records are eligible for direct PhD in several departments.
- GATE/CSIR-NET/UGC-NET (or equivalent) is generally needed for TA-category assistantship for non-IIT master's holders.
- Sponsored/part-time categories require employer sponsorship/NOC and typically relevant professional experience.

Typical timeline
Funding & fellowships
TA-category scholars receive the standard institute assistantship (8 hours/week teaching support) at prevailing rates; RA and project categories are funded from research grants. PMRF and external fellowships (CSIR/UGC-JRF) are also held by many scholars.
Always verify with the official notification. Notifications, department brochures and category definitions are published on the IIT Bombay PhD admissions portal (iitb.ac.in) each semester. Details — dates, tests, weightages, fees — change between cycles; this guide explains the stable pattern so the notification makes sense when you read it.
Frequently asked
What is the difference between TA and RA categories?+
TA scholars are funded by the institute against limited teaching duties; RA/project scholars are funded from a faculty member's research project and usually work within that project's scope. Eligibility and duties differ — read the category definitions in the notification.
Does IIT Bombay admit PhD scholars without GATE?+
Yes in specific cases — e.g. IIT master's graduates, exceptional bachelor's candidates, and sponsored/part-time categories. For assistantship-funded seats, GATE/NET is generally expected of non-IIT candidates.
How competitive is IIT Bombay PhD admission?+
Highly — especially for funded seats in popular departments. A focused research statement, strong fundamentals and fit with advertised research areas are what separate shortlisted candidates.
