IIT Delhi PhD admission for January 2027 opened for Indian candidates on 9 October 2026 at 12:00 noon and is open now; the last date is 29 October 2026 at 4:00 pm, as per IIT Delhi's official advertisement for the 2nd semester of 2026-27. A correction window follows from 30 October to 1 November 2026.

This page covers only IIT Delhi's PhD and MS (Research) round for Semester II 2026-27, which starts in January 2027. It uses the new official advertisement and last round's brochure as the reference. For every January 2027 intake deadline side by side, see our January 2027 PhD last-dates tracker.

What are the key dates for IIT Delhi PhD January 2027?

IIT Delhi has now posted all three application dates. The online application opens on 9 October 2026 at 12:00 noon, closes on 29 October 2026 at 4:00 pm, and the correction window runs from 30 October to 1 November 2026. The Semester II brochure adds the rest: tests and interviews between 9 and 16 December 2026, orientation and registration on 31 December 2026, and classes from 1 January 2027.

Status as of 11 October 2026: the national portal is open, and the PG admissions page now links the Semester II 2026-27 information brochure. The brochure repeats the advertisement's dates (9 October to 29 October, 4 pm; correction 30 October to 1 November) and adds the test, interview and joining dates below.

For reference, the last round (Semester I 2026-27) opened in the third week of March 2026 and closed on 11 April 2026 at 4 pm. This January round gives you about three weeks too, so do not wait for the last day.

The advertisement says foreign nationals are not eligible to apply against it; they use the separate foreign nationals' portal. If you are an Indian applicant, your deadline is 29 October 2026, 4:00 pm. Use the correction window only to fix errors, not to submit late.

Who can apply for IIT Delhi PhD in January 2027?

The official advertisement sets a minimum CGPA of 6.0 on a 10-point scale or 60% marks for General, OBC and EWS candidates, and 5.50 or 55% for SC, ST and PwD, over all years of the qualifying exam. Full-time PhD and MS(R) applicants also need a qualifying GATE or national exam, waived for some CFTI graduates.

The advertisement points to the Semester II brochure for detailed rules, and that brochure is now posted. The points below come from last round's brochure, so confirm each one in the new brochure:

• Minimum marks: CGPA 6.0 or 60%; 5.50 or 55% for SC, ST and PwD (confirmed in the new advertisement).
• GATE or national exam: required for full-time PhD and MS(R) (confirmed in the new advertisement).
• GATE waiver: in the last brochure, for CFTI graduates or students (such as IITs and NITs) who entered through JEE and have CGPA 8.0 or more.
• Part-time and sponsored: minimum full-time experience after the qualifying degree is given in the Semester II brochure.

Departments often shortlist above this minimum. For example, one academic unit's published criteria for Semester I 2025-26 asked B.Tech applicants in the General category for 70% marks and a GATE score of 500 or 600, depending on the degree. Check your target department's page once shortlisting criteria are posted.

Which departments are open this round?

The 2nd semester 2026-27 advertisement lists PhD in 15 departments, 9 centres and 5 schools, and MS(R) in 19 academic units. Admission can be full-time or part-time and depends on seats. Apply separately for each PhD unit and each MS(R) programme you want.

Not every unit takes the same number of scholars, and some may set higher cut-offs. Use IIT Delhi's research-interests pages to match faculty with your topic before you pay.

What is the IIT Delhi PhD application fee?

The official advertisement for this round says General, OBC and EWS candidates pay Rs 200 for each application form, and SC, ST and PwD candidates pay Rs 50. Bank charges are borne by the candidate, and you do not need to send a hard copy of the form or fee receipt.

The advertisement also says SC, ST and PwD students admitted to postgraduate and PhD programmes are exempt from tuition fee. In the Semester I 2026-27 brochure, the semester fee table for a full-time PhD student showed Rs 29,900 (General, OBC, EWS) and Rs 22,400 (SC, ST, PwD), including some one-time charges and excluding hostel charges.

How does IIT Delhi select PhD scholars?

Each department or centre sets shortlisting criteria, usually based on degree marks and GATE score, and then calls shortlisted candidates for a test, an interview or both. The Semester II 2026-27 brochure gives 9 to 16 December 2026 as the range for tests and interviews; your unit will tell you the exact date.

IIT Delhi's Computer Science department, for example, says shortlisted candidates face a test or interview on basics such as programming, data structures and algorithms, operating systems, networks and theory of computation. Other departments test their own core subjects. For interview preparation tips that apply across IITs, see our our general IIT PhD guide.

The advertisement says financial assistance for full-time PhD and MS(R) students will be as per the Semester II brochure. Part-time scholars do not get FIA, so confirm your status before you accept an offer.
