GATE vs JEST vs CSIR-NET for Physics PhD: Which Score Opens What

A physics graduate in India who wants a PhD has five entrance exams to think about, and they do not open the same doors. GATE PH is the broad key: M.Tech through CCMT, PhDs at several institutes, and the only one that BARC’s and DRDO’s latest Physics recruitment adverts accepted. JEST is the research-institute exam, with 31 participating institutes including IISc, TIFR and the IISERs. CSIR-NET is the fellowship exam: pass it at JRF level and you hold a fellowship you can take to an eligible institute that admits you. TIFR’s GS is TIFR’s own. And JAM is for an IIT M.Sc. and the joint and integrated PhD programmes that start after a B.Sc. This guide lays them side by side and then answers the question GATE PH takers ask most: what does my score actually get me?

JEST participating-institutes page (checked 28 Sep 2026); NTA CSIR-NET notice of 29 Aug 2026; GATE 2026 statistical report; CCMT 2026 seat data.

The practical point in that table is shelf life. A GATE score lasts three years. A JEST score lasts until the next-but-one JEST result. A NET JRF must be taken up within two years. A TIFR GS result lasts one admission cycle. If you are applying across two years, GATE and JEST carry you through; TIFR must be sat again.

GATE PH is 100 marks in three hours: 15 of General Aptitude and 85 of Physics, with one-third negatives on MCQs only. CSIR-NET Physical Sciences is also three hours but in three parts: you answer 15 questions of Part A, 20 of Part B and 20 of Part C, with a 25% negative in all three parts: 0.5, 0.875 and 1.25 marks for a wrong answer, against 2, 3.5 and 5 for a right one, 200 marks in all. Its JRF has an age limit of 30 (on 1 July 2026 for the June cycle); there is none for Assistant Professor or PhD-only qualification. JEST changed its question pattern for 2026; read the new pattern on its site before you practise from old papers. TIFR GS is a three-hour Physics paper in the afternoon.

A PhD place and the money that comes with it are two different things. A CSIR-NET JRF is a fellowship you hold yourself, usable at an eligible institute that admits you, under CSIR/UGC and host rules: ₹37,000 a month for two years, then ₹42,000 as an SRF, with ₹20,000 a year contingency. A GATE or JEST score gets you into an institute, which then pays you from its own or a scheme’s funds. At the DAE centres that take GATE PH, the monthly rates for a direct PhD match NET’s: IGCAR and IPR pay ₹37,000 in years one and two and ₹42,000 after, with ₹60,000 a year contingency, and IPR adds HRA. An IGCAR integrated PhD starts lower, at ₹25,000 in year one.

JEST is run for the research institutes, and its site lists 31 participating institutes, among them IISc, TIFR, ICTS, NCRA, IUCAA, seven IISERs, NISER, IMSc, HRI, IOP, RRI, SINP, PRL, IGCAR, RRCAT, IPR, HBNI, IIST, the S.N. Bose Centre, Bose Institute, IIA, ARIES, VECC and the UGC-DAE Consortium. ANRF (formerly SERB) recognises it as a NET. There is no eligibility condition to sit JEST; each institute sets its own. A PhD needs an M.Sc. in Physics, but a B.E. or B.Tech. is accepted at IISc, IMSc, ICTS, IUCAA, NCRA, TCIS, RRI and IISER Mohali, Pune and Thiruvananthapuram, and NISER’s integrated PhD takes a first-class B.Sc. Physics or B.E. Engineering Physics.

Two dates in this list are worth a second look. TIFR’s GS on 13 December is two months before GATE and uses much of the same physics, so it doubles as a full-length mock. And 14 February is both JAM day and one of the six GATE days; GATE has not yet said which day PH is on. GATE is open from the third year of a bachelor’s degree, so a final-year B.Sc. student can be registered for both. If GATE PH lands on 14 February in the same session as JAM, you cannot sit both; check the GATE paper-wise schedule the day it is published.

The central counselling for NIT, IIIT and other centrally funded M.Tech seats (CCMT) listed PH as an admissible paper for 123 programme groups at 39 institutes in 2026. About 36 of those groups are physics by name: materials, nano, photonics, lasers, quantum technology and semiconductors. There is a catch that every “GATE PH M.Tech cut-off” list misses. NIC’s closing scores are pooled across every GATE paper a group admits. A group that takes 13 papers closes at a score set mostly by EC and EE candidates, not by physicists. Only when a group admits PH alone does its closing score describe PH candidates.

The PH-only group is the most useful row on the page. At NIT Rourkela the same programme ran a mixed group (seven papers, closing 664 in Round 1) and a PH-only group that closed at 420 for OPEN, about 30.5 marks on the 2026 field. Its reserved-category seats closed lower still.

What we could not find: IIT M.Tech (COAP) and IISc closing scores for PH candidates, and institute-level PH shortlisting cut-offs for IIT and IISc physics PhDs. We have left them out rather than guess.
