IIIT-Delhi Admission Through GATE: M.Tech CSE, PGCAT and PhD Routes

IIIT-Delhi sits in Okhla Industrial Estate, Phase III, New Delhi, near Govind Puri Metro Station, according to its contact page. Its admission documents describe it as a state university established by the Government of NCT of Delhi. That matters for the process: it is outside both COAP and CCMT, so every step from application to seat offer happens on IIIT-Delhi's own portal.

The 2026 M.Tech admission page lists four programmes:

• M.Tech. (CSE): with optional specialisations in Artificial Intelligence, Data Engineering, Information Security and Mobile Computing, or no specialisation.
• M.Tech. (Research) in CSE: a two-year research-led master's with a thesis from the first year.
• M.Tech. (ECE): with specialisations in VLSI & Embedded Systems, Machine Learning and Communication.
• M.Tech. (CB): Computational Biology, open to every GATE paper.

Specialisation seats are not fixed in CSE or ECE. The CSE details page says all seats are open and you graduate with a specialisation by meeting its course requirements.

For a GATE seat in M.Tech. (CSE), the CSE details page says the "CS & DA" papers are considered, and the score counts only if your marks were above that year's GATE qualifying marks. Scores from 2024, 2025 and 2026 were valid in the 2026 cycle. The degree condition is a B.Tech./B.E. in CS/IT or an allied area, an MCA, or an M.Sc. in CS/IT, with 65% marks.

M.Tech. (Research) in CSE asks more of your degree: 75% or equivalent in a B.E./B.Tech. in CSE/IT/ECE/EE, an MCA, or an M.Sc. in Mathematics or Statistics, plus a mandatory GATE score. The research programme page lists CS, EC, EE, MATH, ST and DA.

The M.Tech FAQ, last updated in March 2026, swaps the extra papers: it gives the longer list to the regular programme and only DA and CS to the research one. Every source includes DA and CS for both, so a DA or CS taker is covered. With any other paper, ask the admission office before paying the fee.

For M.Tech. (ECE) the ECE page counts CS, EC, EE, IN and DA, but the degree must be in ECE/EE or an M.Sc. in Electronics. M.Tech. (CB) accepts a valid score in any paper relevant to your degree, per the CB page.

The institute's own test decides most M.Tech. (CSE) offers. Under the 2026 rules on the CSE page:

1. A GATE applicant who meets the basic eligibility sits PGCAT-IIITD.
2. An applicant with a GATE score of 600 or above is exempt and is awarded full PGCAT marks for the merit list.
3. A cut-off is set for each category, and an All-India Rank (AIR) merit list is drawn from PGCAT performance for candidates above it.
4. Offers go out in AIR order.

A score below 600 does not stop you applying on a GATE seat; you simply take the test. You may apply in only one category, GATE or non-GATE, and a duplicate is treated as a GATE application.

The PGCAT syllabus for 2026-27 describes an online test in several cities: 40 multiple-choice questions in line with the GATE CS syllabus, 2 hours long, in four sections (Engineering Mathematics, Programming and Data Structures, Algorithms, and the remaining topics). A DA taker should note that the test follows CS, not DA, so revise data structures and algorithms even if your GATE preparation leaned on probability and machine learning. The venue is given with the admit card, which in 2026 came by email.

PGCAT was held on 3 May 2026. The 2026 merit list for GATE seats prints rank, name and application number only, with no score or PGCAT mark.

The research programme uses the same test with an extra stage. Per the programme page, a 600+ GATE scorer skips PGCAT and is called straight to interview; everyone else is shortlisted for interview if they clear the category cut-off in PGCAT. A composite of PGCAT and interview, with a cut-off per category, produces the AIR merit list. The FAQ says the interviews are online, so a candidate from the south does not need to travel for this stage. In 2026 the interviews were scheduled for 7 May (tentative).

On accepting an offer you rank possible thesis supervisors, usually allotted in merit order. The page says students may convert to the full-time PhD, typically after one year. You can apply to both M.Tech. (CSE) and the research programme in one cycle and accept one offer.

M.Tech. (CSE) and M.Tech. (ECE) keep separate non-GATE seats. For CSE, every eligible non-GATE applicant is invited to PGCAT and ranked on it in the same way; for ECE, the shortlist is drawn on degree percentage and followed by an online interview. The research programme and CB need a GATE score.

The difference is money. The CSE page says the M.Tech. assistantship (Rs. 12,400 a month through AICTE direct benefit transfer, for up to 24 months) goes only to students with a valid GATE score admitted on a GATE seat, and the FAQ confirms that a GATE holder who takes a non-GATE seat does not get it. If you have a valid DA or CS score, apply on the GATE side.

The M.Tech admission page gave these dates for 2026:

Step	Date
Online application	16 March to 13 April 2026
Admit cards for CSE and CSE-Research	20 April 2026
PGCAT-IIITD	3 May 2026
Online interview, CSE-Research	7 May 2026 (tentative)
Merit list and Round 1 allotment	18 May 2026
Round 2 / Round 3 allotment	29 May / 12 June 2026
Online spot round	10 July 2026
Document verification on campus, CSE and CSE-Research	15 July 2026
First semester	10 August 2026

The Round 1 allocation notice says an allotment is provisional until you pay the admission fee online by the round's deadline (25 May in 2026); an unpaid seat is cancelled and you drop out of later online rounds. A compulsory refresher module follows admission.

Hostel rooms depend on availability, and the CSE page says applicants from outside Delhi get preference. The 2026-27 fee table there was marked tentative. Queries go to mtech-admissions@iiitd.ac.in or 011-26907129.

PhD admission is a separate process. The PhD admission page describes regular rounds in February to April and September to November each year, and a rolling mode for applicants who have already agreed a topic with a faculty member. The Winter Session 2026-27 call covers Computational Biology, CSE, ECE, Human-Centered Design, Mathematics, and Social Sciences and Humanities, and says GATE is not mandatory for some departments.

The discipline eligibility PDF asks a CSE applicant for a B.Tech./B.E./M.Tech./MS/M.E. in CSE, IT, ECE, EE or an allied area with CGPA 7.5 (or 70%), or the stated MCA/M.Sc. alternatives, and names no GATE requirement for CSE. Mathematics is different: it needs a JRF, INSPIRE or NET eligibility, or a GATE score of at least 400. Selection is on academic record and statement of purpose, then a written test and/or interview, and shortlisted candidates from outside the NCR are reimbursed sleeper-class train or bus fare.

For the Winter 2026-27 round, applications run from 8 October to 15 November 2026 (5 PM), CSE interviews are scheduled for 7 to 17 December 2026, and results for 24 December 2026. The call states a fellowship of Rs. 60,000 a month for regular PhD students.

IIIT-Delhi says it sets a cut-off for each category, but it did not publish the numbers for 2026. Its merit lists and allocation notices give ranks and application numbers, not GATE scores or PGCAT marks, so this page shows no cut-off. The one published threshold is the 600 GATE score that exempts you from PGCAT.

For 2027, if the pattern holds the window opens around March; watch the M.Tech admission page. Aim for 600 with the GATE DA guide or the GATE CSE guide, and drill data structures and algorithms in practice as PGCAT backup. Other Delhi options: DTU and IIT Delhi.
