Joint Entrance Screening Test(JEST)

About the exam

About JEST

The Joint Entrance Screening Test hands out interviews, not seats. The JEST 2026 official website says the score is used by the participating institutes together with their respective eligibility criteria to shortlist candidates for PhD, Integrated PhD and MSc programmes in Physics, for PhD and Integrated PhD programmes in Theoretical Computer Science, and for a PhD programme in Computational Biology. That sentence carries the whole role of the exam. JEST screens, and each institute then decides for itself.

JEST is held once a year in two subjects, and you pick one of them. A candidate can appear for the JEST in Physics or in Theoretical Computer Science but not for both in a given year, according to the JEST 2026 FAQ page. The same FAQ says a common JEST exam is conducted for PhD, Integrated PhD and MSc programmes, so there is no separate paper by programme level. Computational Biology is the exception worth knowing: the FAQ states that JEST is meant for students from a Physics background to take up research in that field, and that interested candidates must take the Physics paper.

JEST pitches its papers at a level rather than at a year of study. The examination is at the level of an MSc, or an advanced BSc in Physics and Computer Science, JEST's home page records.

Who runs it changes. The site is signed off by the JEST Consortium and names IISER Tirupati as the organising institute for the JEST 2026 cycle, with the JEST 2026 postal address at the Department of Physics, IISER Tirupati, Panguru, Yerpedu, on the JEST contact page. The status that outlives any one host institute is the recognition: the Anusandhan National Research Foundation, previously known as the Science and Engineering Research Board, recognises JEST as a National Eligibility Test in office memorandum OM No. SB/S9/Z-01/2015, and fellows working in SERB programmes who have qualified in NET are eligible for the appropriate fellowship, the home page states. The memorandum itself is narrower than that phrase sounds. It is an order revising the emoluments of research personnel, and it lists JEST among the examinations conducted by various Central Government departments and agencies that are considered a National Eligibility Test, so that a fellow already working in a SERB programme who has qualified in one of them draws the enhanced rate. It says nothing about the exam's syllabus, its conduct or its standard.

JEST highlights

Calendar

Important dates

The JEST 2026 cycle has run its full course. Its timeline, as the organising institute published it, was this.

The closing date moved after it was first advertised. The JEST 2026 flyer carried an application window of 26 Feb to 23 Mar and an exam date of Sunday, 12 April 2026. The JEST 2026 home page then showed that closing date struck through and replaced, and records that the application submission ended on 25 March 2026. The test itself was held on 12 April 2026, from 2 pm to 5 pm.

Nothing on the site announces a following cycle. Its banner still reads that this is the official website of JEST 2026, and the newest entry in its own timeline is the declaration of results on 30 April 2026.

Who can apply

Eligibility criteria

JEST does not gate the test itself. There are no specific criteria to appear for JEST, says the JEST eligibility page, which adds that even a candidate who has just completed the first year of a Bachelor's programme might still be able to use a JEST 2026 score. The FAQ page backs that up from two directions: there is no restriction on age for appearing in JEST, and no restriction on the number of times one can appear. Applications are accepted under the General, EWS, Scheduled Caste, Scheduled Tribe and Other Backward Class categories.

For the PwD category, the JEST 2026 FAQ page applies the Rights of Persons with Disabilities Act, 2016, under which persons with benchmark disabilities qualify for reservation of seats. It defines a person with benchmark disability as a person with not less than forty percent of a specified disability where that disability has not been defined in measurable terms, as certified by the certifying authority, and lists the specified categories from hearing impairment and blindness to locomotor disability and dwarfism.

The real bar is set by the institute you want to join, and JEST publishes what it calls tentative criteria for each programme, telling candidates to confirm them on the institutes' own websites.

A BTech in Mechanical or Civil engineering is not a disqualification either. The FAQ says such students could appear, while pointing out that the examination is conducted only in Physics and Theoretical Computer Science and that admission criteria differ across the participating institutes.

Step by step

Application process and fee

Registering and applying are two separate jobs on the JEST portal, and the application form only unlocks once the registration has been verified. The FAQ describes registration as submitting basic information including your name, e-mail ID and phone number, generating an OTP sent to both, and then verifying that information in a Declaration section; the application form that follows asks for Personal Details, Educational Details and Exam City, ending in payment. Successful completion of the payment concludes the application procedure.

Get a registration field wrong and the fix costs a second fee. You cannot edit personal details such as date of birth, email address or mobile number once you confirm the submission, and the FAQ's remedy is to register again with a new email ID, with no refund and no admit card for the earlier registration. The application is then considered for the latest registration.

The application fee for JEST 2026 had two rates.

That fee was non-refundable, and payment was accepted through an online payment service using debit card, credit card, net banking or UPI only, the FAQ page states. The documents to be uploaded are the relevant certificates for SC, ST or PwD applicants.

Candidates from boards that report no marks at all get their own rule. Where a board reports Class 10 results as "Pass" without numerical marks, the JEST 2026 FAQ page advises applicants to enter 70% in the marks field only to allow the form to be submitted, and states plainly that the value is purely indicative and will not be considered for evaluation, shortlisting or any stage of the selection process, with the original certificate kept available for verification.

Before the exam

Admit card and exam day

Admit cards are downloaded, never delivered. The FAQ says they are available from the JEST registration portal a few days before the examination, will not be sent by post or email, and that a candidate should bring a print-out of the downloaded admit card and one photo ID card to the examination centre. The timeline on the home page set the download date at 07-04-2026.

What you may not bring is listed precisely: books, charts, graph sheets, tables, calculators, mobile phones, digital diaries and electronic communication or computing devices are not allowed in the examination hall, according to the FAQ page. There is no choice of slot to manage either, because the exam date and exam shift are uniform for all candidates.

Candidates with disabilities get a defined set of provisions on the same page. The time extension is 20 minutes per hour, which comes to a total extension of one hour for the full test, with or without a scribe. A hearing aid is brought by the candidate; a wheelchair is provided by the test centre on request made in the application form; a magnifying screen is provided by the centre on request. A scribe or reader has to be arranged and paid for by the candidate, must bring valid proof of identity and a passport sized photograph, must sign a declaration about educational qualifications at the venue, and should not have a career background in Physics or Computer Science.

Structure

Exam pattern

JEST 2026 was delivered on a computer, which is not the same thing as being an online exam. The FAQ page draws the distinction itself: JEST is a digital or Computer Based Test, not an Internet-Based Test, and candidates read the questions on a computer terminal and choose an answer by clicking on the correct option. A candidate cannot take it from any computer, because the workstation is assigned at the test centre based on the selections made during registration.

The question pattern changed for this cycle, and the site says so on its own front page before sending the reader to the FAQ for the detail. The JEST 2026 FAQ page sets out the JEST 2026 Physics exam as 180 minutes and 100 marks in three parts.

The Theoretical Computer Science paper runs for the same 180 minutes but is built differently, in two parts, the same FAQ page says. Part A carries 25 multiple-choice questions at 3 marks for a correct answer and -1 for an incorrect one, with unattempted questions fetching 0 marks. Part B contains 9 questions, of which a candidate is expected to solve three of the eight-mark questions and two of the thirteen-mark questions; more may be attempted, in which case marks are given to the best three and the best two respectively. Part B closes after 105 minutes of the 180, so the long-answer half carries the tighter deadline.

What to study

Syllabus

Six headings hold the whole of the Physics side: Mathematical Methods, Classical Mechanics, Electromagnetism and Optics, Quantum Mechanics, Thermodynamics and Statistical Physics, and Electronics, as the JEST Physics syllabus sets them out. It is short enough to read in one sitting, and the detail inside is specific rather than indicative: Sturm-Liouville theory, the Kepler problem, multipole expansion, time dependent perturbation theory, Fermi and Bose gases, and the basics of OPAMPs all appear by name.

Theoretical Computer Science is scoped by area instead. A Note on the TCS Exam, issued by the Theoretical Computer Science group at the Institute of Mathematical Sciences, says the test focuses on Analytical Reasoning and Deduction, Combinatorics, Data Structures and Algorithms, Discrete Mathematics, Graph Theory, and Principles of Programming, with familiarity with the basics assumed in each. The same note says there is no specified portion for the test, and that it is designed to check the applicant's understanding of foundational aspects of computing.

Across both subjects, the FAQ places the questions on the general syllabi of graduation and post-graduation level courses offered by various Indian universities and institutions.

How to prepare

Preparation and books

What JEST itself hands a candidate is a small, honest set of material, all of it on the home page: the Physics syllabus, a sample Physics question paper, the note on the TCS exam, and a sample TCS question paper. The FAQ is blunt about the limit of that: JEST question papers are not made available officially, though some questions from previous years' examinations are on the home page.

The two sample papers are not the same kind of document, and it matters. The JEST 2026 sample Physics question paper opens with a note that the Physics question pattern has changed for JEST 2026 and restates the three-part structure, so its questions sit under the current scheme. The sample TCS question paper is the Theoretical Computer Science question paper from JEST 2021, carrying its own cover note that the question pattern has changed for JEST 2026; its Part B is built around eight-mark and twelve-mark questions, where the 2026 FAQ describes eight-mark and thirteen-mark ones.

The prep note behind that paper, A Note on the TCS Exam, prints a numbered list of suggested texts of its own, opening with Liu's Elements of Discrete Mathematics and taking in Horowitz and Sahni, Aho, Hopcroft and Ullman, and Cormen, Leiserson and Rivest along the way, and it tells the reader plainly that they do not need to read all the books. One line in it has aged: the note says the TCS screening test will be held typically on a Sunday in the middle of February every year, while the JEST 2026 timeline put the test on 12 April.

Where it is held

Exam centres

The centre list is published as cities rather than addresses. For JEST 2026 the exam centres page named Ahmedabad, Aligarh, Amritsar, Bangalore, Bardhaman, Bhopal, Bhubaneswar, Chandigarh, Chennai, Coimbatore, Delhi, Goa, Guwahati, Hyderabad, Indore, Jaipur, Kanpur, Kharagpur, Kochi, Kolkata, Kozhikode, Madurai, Malappuram, Mangalore, Mumbai, Nagpur, Nainital, Patna, Prayagraj, Pune, Raipur, Rajkot, Ranchi, Roorkee, Sambalpur, Silchar, Siliguri, Srinagar, Thiruvananthapuram, Tirupati, Udaipur, Vijayawada and Vishakhapatnam. JEST does not publish a count alongside that list.

Your city is chosen inside the application form, at the Exam City stage described in the FAQ, and the specific workstation is then assigned at the centre.

After the exam

Answer key

The answer key for JEST 2026 came with a short, hard window. The JEST 2026 home page records that the answer keys were available from 12 noon on 17.04.2026 and were open to challenges by candidates for 48 hours, till 12 noon on 19.04.2026. The announcement does not name a fee for lodging a challenge.

Those challenges changed the key. The score cards were prepared on the basis of an updated answer key, which JEST published as a separate Physics file on the same page, so a candidate comparing a raw self-score against the first key could reach a different number from the score card.

Scores

Result and scorecard

JEST 2026 results went live on 30.04.2026, and the JEST 2026 home page directs candidates to download the score card by logging into the application portal. There is no ranked public merit list on the site to read alongside it.

The score then keeps working for two more cycles. The score for JEST 2026 will remain valid till the date of declaration of results of JEST 2028, the FAQ page states, and the eligibility page repeats it as the reason a candidate can sit the test early in a Bachelor's programme. That validity is real in practice, not just on paper: the IISc Admission Notice for 2026-27 shortlists Integrated PhD candidates in Physical Sciences on a JEST 2025 or JEST 2026 score, and requires a national entrance test score card to be valid as on 01 August 2026.

Scores you need

Cutoff

What JEST 2026 handed back was a score card with nothing to measure it against. None of the announcements on the official site attaches a cutoff score, a percentile or a qualifying band to that card, and the shortlist that decides anything is drawn up by an institute rather than by the consortium.

You can see what that looks like at an institute that publishes its list. For the 2026 cycle, the IMSc TCS PhD and Integrated PhD Admissions 2026 page named the JEST candidates shortlisted for interviews to its PhD and Integrated PhD programme by roll number alone, with no marks attached, and gave 9 and 10 July 2026 as the tentative interview dates. A published cutoff would not have told those candidates anything the list did not.

Getting a seat

Counselling and seat allotment

JEST's own involvement stops at the score card, and the candidate carries it to each institute separately. The eligibility page is explicit about where the work moves to: for the results of JEST to be useful, a candidate must qualify the additional eligibility criteria of the institutes they want to apply to, and those criteria sit on the institutes' own websites.

What replaces counselling is an interview at each institute. The IMSc doctoral programme page states the mechanism directly: the route to the IMSc graduate research programme is through an interview, and candidates are pre-screened through their performance in a national level qualifying examination, of which JEST is one. IMSc says its application deadlines usually fall in mid-February and that candidates selected through these exams are invited for interviews in May to July. Its 2026 TCS admissions round ran to that shape, with a second round of interviews held online on 10th August and a final list of selected candidates posted on 14th August.

IISc arranges the same two steps differently by programme. Its 2026-27 admission notice shortlists Integrated PhD candidates in Physical Sciences for interview on the JEST score and then selects on the interview, or on combined JEST and interview performance, while for the MSc in Physics it says selection will be based on 100% performance in the JAM (PH) 2026, JEST 2025 or JEST 2026 rank, with no interview stage named.

Where it is accepted

Participating institutes

Every institute on this list is published with the research areas it admits into, and those areas are the part a candidate has to read, because they differ sharply from one institute to the next. The home page names Aryabhatta Research Institute of Observational Sciences in Nainital, Bose Institute in Kolkata, Harish-Chandra Research Institute in Prayagraj, Homi Bhabha National Institute in Mumbai, the Indian Institute of Astrophysics in Bangalore, the Indian Institutes of Science Education and Research at Berhampur, Bhopal, Kolkata, Mohali, Pune, Thiruvananthapuram and Tirupati, the Indian Institute of Science in Bangalore, the Indian Institute of Space Science and Technology in Thiruvananthapuram, the Indira Gandhi Centre for Atomic Research at Kalpakkam, the Institute for Plasma Research at Gandhinagar, and the Institute of Physics in Bhubaneswar. The rest of the list runs through the Inter-University Centre for Astronomy and Astrophysics in Pune, the International Centre for Theoretical Sciences in Bangalore, the National Centre for Radio Astrophysics at TIFR Pune, the National Institute of Science Education and Research in Bhubaneswar, the Physical Research Laboratory in Ahmedabad, Raja Ramanna Centre for Advanced Technology in Indore, the Raman Research Institute in Bangalore, Saha Institute of Nuclear Physics in Kolkata, Satyendra Nath Bose National Centre for Basic Sciences in Kolkata, the Tata Institute of Fundamental Research in Mumbai and its Centre for Interdisciplinary Sciences in Hyderabad, the Institute of Mathematical Sciences in Chennai, the UGC-DAE Consortium for Scientific Research in Indore and the Variable Energy Cyclotron Centre in Kolkata.

Two of those entries carry the whole non-Physics side of the exam. IMSc Chennai is the only institution currently offering a PhD in Theoretical Computer Science, the FAQ page states, and IMSc also offers the PhD in Computational Biology that the Physics paper screens for. The JEST site lists IMSc's research areas as Theoretical Physics, Theoretical Computer Science and Computational Biology.

For a candidate, the practical consequence is that the list is a starting point for reading, not a set of doors that open on one score. Each institute has its own eligibility criteria, the FAQ says, and directs candidates to the websites linked from the participating institutes page.
