So many institutes in one city is an advantage for you. Suppose you are a biology postgraduate with a JGEEBILS score. NCBS, inStem and IISc can all interview you without you leaving town.

Which entrance test gets you an interview at which institute?

Many scholars are paying application fees at five or six places without checking. Better you first write your scores next to each institute and see where you actually qualify. This list follows the TIFR GS-2026 eligibility table and the notice of each institute.

• JEST: this is the main entry for RRI and IIA. For ICTS physics it is one of four accepted routes. IISc has also listed it in its mid-year notice.
• TIFR GS test (JGEEBILS for biology): used by NCBS and ICTS. For the mathematics PhD at CAM, this is the only score they accept. IISc and inStem take JGEEBILS scores as well.
• CSIR-UGC NET (JRF): accepted in JNCASR’s September round, and at RRI, IIA, ICTS, NCBS, IISc and the AcSIR labs. At IISc and JNCASR, a NET with lectureship only will not qualify you.
• GATE: IISc takes it for engineering. NCBS wants the top 5 percentile, or the top 10 if you have six months of research experience. RRI accepts GATE in physics, and IIA needs a score above the 95th percentile.
• No national score: ISI picks its Junior Research Fellows through its own test and interview. AcSIR takes self-sponsored engineering candidates and its own project staff. For the other institutes, plan on having one.

Look at the percentile cut-offs carefully. On its August 2026 page, NCBS asked for a national exam score above the 95th percentile. Two more groups were also considered if they had six months of continuous research experience. The first group was GATE candidates in the top 10 percentile. The second was NET qualifiers who did not have JRF. Then IIA’s eligibility page has two conditions which many applicants are missing. You need at least 60% marks throughout your academic career, and the age limit is 28 at the time of admission.

What changes when the degree comes from JNU, Pondicherry or RCB rather than the institute?

Your research happens in Bengaluru, but your registration is with some other body. Mostly that registration also comes later than scholars expect.

• RRI. As per the 2026 admission poster, research students get registered for the PhD with JNU only after they complete the first-year coursework. They also have to meet the other requirements for confirmation of candidature. RRI is part of the Joint Astronomy Programme with IISc too.
• IIA. The IIA-PU PhD is run together with Pondicherry University. In the first year there is classroom coursework in astrophysics and a three-month project. The integrated M.Tech.-PhD (Tech.) in astronomical instrumentation works differently. IIA’s programme page says the first year is spent in Kolkata, in the University of Calcutta’s Department of Applied Optics and Photonics, and after that you return to IIA.
• NCBS and ICTS. Here the PhD registration is at TIFR, a deemed university. NCBS says this mostly happens one and a half to two years after joining, once the coursework and a qualifying examination are over.
• inStem. Registration is at the Regional Centre for Biotechnology. Here also it comes only after coursework and a qualifying examination, which covers biological fundamentals and research design.

In practice you will follow two sets of rules. The institute handles your coursework, committee meetings and day-to-day supervision. Registration, thesis submission and the degree certificate come under the regulations of the awarding university. So at the offer stage itself, take the institute rules and the university regulations both in hand. Later your employer or a selection board may ask which university your PhD is from. The correct answer is the awarding body, not the lab.

How do CSIR-NAL and CSIR-4PI take PhD students through AcSIR?

There are two CSIR laboratories in Bengaluru. The first is the National Aerospace Laboratories, which has campuses at Kodihalli on HAL Airport Road and at Belur. The second is the CSIR Fourth Paradigm Institute, located on the NAL Belur campus. Neither lab gives degrees by itself. Their PhD students are enrolled with AcSIR, and AcSIR says it covers 78 research institutes. Your application goes through AcSIR’s own portal.

The August 2026 notice of AcSIR closed on 14 April 2026. It charged ₹1,000 as application fee (₹500 for SC/ST/PwD candidates). That notice gives the eligible categories as below.

• PhD (Science): you need a valid national fellowship (CSIR, UGC, ICMR, DBT, INSPIRE, RGNF and others). Temporary project staff of an AcSIR institute can also apply with an NOC. A permanent employee sponsored by an industry or an AcSIR institute is the third option.
• PhD (Engineering): everything above, and self-sponsored candidates also. This helps a mechanical or aerospace M.Tech. graduate without GATE, since few other research institutes in Bengaluru will even consider such an application.

In the CSIR-CFTRI version of the notice, selection is by aptitude test or interview at the institute itself. If you already work in industry, note the sponsored-employee category. Our part-time PhD in Bengaluru page compares it with IISc’s External Registration Programme.

When do Bengaluru’s research institutes take applications?

Between February and July, most of the year’s admission decisions get made. These dates are from the 2026 notices only, and in the next cycle the dates will be different.

• February to March: the IISc window for the August session ran from 11 February to 23 March 2026. ISI took applications from 12 February to 26 March 2026, after an extension.
• March to April: For NCBS the national-exam route closed on 31 March 2026. AcSIR kept its August session window open longer, till 14 April 2026. As per ICTS, its interviews based on the TIFR GS test are typically held in March and April.
• April and May: IIA was open from 2 April to 11 May 2026 (extended). RRI extended its last date to 17 May 2026. For ISI, the date of the admission test was 10 May 2026.
• May to July: RRI interviews were tentatively planned for May and June 2026. For JEST, GATE and NET candidates, ICTS interviews are typically in June and July.
• September to November: JNCASR’s September round ran from 11 to 30 September 2026. The IISc window for the January session was 6 to 26 October 2026.

Many scholars don’t even know JNCASR has a September round. It takes only few students and the notice comes out late in the year. Its brochure invited NET-JRF holders to six units (the Evolutionary and Organismal Biology Unit was not included). Candidates had to complete their degree by 30 September 2026. If you cleared JRF in the summer when the spring deadlines were already over, this round gives you second chance.

Which Bengaluru institute suits your master’s degree?

M.Sc. Physics. Write JEST, because that one exam opens RRI, IIA and ICTS together. In RRI’s 2026 requirement list there were 25 openings across its four groups, and soft condensed matter had the largest share. Apply to IISc also if you have GATE or NET-JRF.

M.Sc. in a life science. With JGEEBILS and a JRF, you are covered for NCBS, inStem and IISc. Some scholars have JRF but only a modest percentile. For them, JNCASR’s molecular biology and neuroscience units are worth a look, since those units asked for NET-JRF and called candidates for interview on that basis.

M.Sc. Mathematics or Statistics. ISI’s Bengaluru centre is one option, for statistics, mathematics, and quality, reliability and operations research. The TIFR GS mathematics test takes you to CAM and ICTS. IISc’s mathematics department is the other choice.

M.E. or M.Tech. With GATE, go for IISc. Without GATE, CSIR-NAL through AcSIR is the place to try. And if you have NET-JRF, the engineering mechanics unit at JNCASR is open for you.

The stipend in these institutes is as per the national scale. RRI, JNCASR and IIA each quoted ₹37,000 per month for years one and two, and it goes up to ₹42,000 after that. RRI also gives a book grant of ₹50,000 over five years. In case none of these institutes suits you, the city’s university routes (Bangalore University, VTU, CHRIST) works with different tests and calendars. Those are explained on our Bengaluru admission page.
