IIT Bombay has set a new doctoral milestone, awarding 620 PhD degrees during the 2025-26 academic year. The institute says this is the highest annual PhD count by any IIT. The total formed part of 3,763 degrees awarded to 3,442 students during its 64th Convocation cycle. Yet the celebration came with a tougher message for doctoral scholars: PhD registrations cannot continue indefinitely.
Under IIT Bombay’s current PhD rules, regular PhD registration is valid for six years, while Masters+PhD routes generally have seven years. Most students can seek extensions only up to eight years, after which registration is cancelled. External and College Teacher categories can continue up to 10 years.
How Did IIT Bombay Reach A Record 620 PhD Degrees?
The 620 doctorates were split across two degree-award periods. IIT Bombay’s official Spring Convocation announcement shows that the February session conferred 269 PhD degrees, while the August Departmental Degree Award Functions accounted for another 351. Across 2025-26, the institute awarded 1,713 undergraduate, 1,430 postgraduate and 620 doctoral degrees.
The record was not simply about a larger graduating batch. IIT Bombay reviewed long-running doctoral registrations and identified scholars whose work had stretched well beyond normal timelines. Careers360’s report on the convocation said officials found roughly 100 to 125 PhDs pending for more than eight years, including cases continuing for 12 years or longer.
Key figures from IIT Bombay’s 2025-26 degree cycle include:
- 3,763 degrees awarded to 3,442 students across the academic year.
- 620 PhDs, including 269 in spring and 351 in the August session.
- 3,333 degrees conferred on 3,042 students during the Autumn session.
- 791 graduating students were women, while 2,651 were men.
- IIT Bombay called 620 the highest annual PhD total by any IIT.
Why Has IIT Bombay Put An Eight-Year Ceiling On Most PhDs?
The rule is designed to stop doctoral registrations from staying open for unusually long periods. Institute officials said reviews found delays linked to guide availability, outside employment, changing professional priorities and Covid-era disruptions. In some cases, the institute contacted scholars and examined why research had remained unfinished.
There is an important distinction between the normal registration period and the outer ceiling. IIT Bombay’s official PhD regulations state that regular registration is valid for six years and Masters+PhD registration for seven years. Scholars crossing those points must apply for an extension during the Annual Progress Seminar process. The maximum is eight years for most categories. External and College Teacher scholars may continue up to 10 years.
The same rules say registration will be automatically cancelled after the applicable eight-year or 10-year maximum. That gives departments a formal deadline while retaining some flexibility for research that genuinely takes longer.
What Else Changed Around IIT Bombay’s 64th Convocation?
The convocation also highlighted a wider research push. Careers360 reported that IIT Bombay has approved new research centres and PhD activity in semiconductors, defence technology, medical technology, quantitative finance and traditional Indian knowledge. It is also offering internships to final-year NIT students, with possible routes into master’s or PhD programmes based on performance.
Research recognition was prominent. Fifty students received Naik and Rastogi Excellence in PhD Research Awards for 2024-2026, while 44 received Institute Silver Medals. Across the academic year, Chemistry produced 77 PhDs, Mechanical Engineering 49 and Humanities 40.
IIT Bombay’s official X post on the 64th Convocation also published the 2025-26 figures, saying 3,763 degrees were awarded, including the record 620 PhDs. The post described it as the highest number of PhD degrees awarded by any IIT in one academic year.
What Does The New PhD Timeline Mean For Current And Future Scholars?
For students, the policy creates a firmer administrative clock. A scholar approaching six years cannot assume registration will simply continue. Progress reviews, pre-synopsis work and extension paperwork become more important as the deadline approaches.
The rule may also push departments to intervene earlier when research stalls. Experiments can fail, supervisors may change and personal or professional commitments can disrupt a thesis, but unresolved cases are less likely to remain open for a decade.
The record 620 PhDs therefore tells two stories at once. IIT Bombay is producing more doctoral graduates, while also trying to shorten excessively long research timelines. The next few graduating batches will show whether 620 reflected backlog clearance, sustained research growth or a combination of both.
