Joint Admission Test for Masters
The Joint Admission Test for Masters (JAM) is an annual national-level entrance examination in India, jointly administered by the Indian Institutes of Technology (IITs) and the Indian Institute of Science (IISc), Bangalore, to facilitate admissions into postgraduate science programs such as M.Sc., Joint M.Sc.-Ph.D., and other post-bachelor's degrees at IITs, IISc, and select other centrally funded technical institutions.[1][2] The test serves as a standardized gateway for science graduates seeking advanced education in rigorous academic environments, having established itself as a benchmark for transitioning undergraduates into elite postgraduate training over the past two decades.[2][3] Organized on a rotational basis among participating IITs, with IIT Delhi coordinating JAM 2025 and IIT Bombay set to handle JAM 2026 as a computer-based test (CBT) featuring seven subject-specific papers—Biotechnology, Chemistry, Economics, Geology, Mathematical Statistics, Mathematics, and Physics—the examination assesses candidates' aptitude through multiple-choice and numerical answer-type questions tailored to undergraduate-level curricula.[4][5][6] Eligibility to appear requires only a bachelor's degree or equivalent in a relevant field, with no minimum percentage marks or age limit imposed by the exam authority, though individual institutes apply their own admission criteria post-qualification.[7][8] This merit-based selection process, drawing tens of thousands of applicants yearly, underscores JAM's role in democratizing access to high-caliber scientific research and teaching opportunities without reliance on subjective evaluations.[2]Overview
Purpose and Scope
The Joint Admission Test for Masters (JAM) functions as a national-level entrance examination designed to facilitate admissions into postgraduate science programs, including Master of Science (M.Sc.) degrees and integrated M.Sc.-Ph.D. dual degrees, at the Indian Institutes of Technology (IITs) and affiliated institutions. Its core purpose is to identify and admit meritorious candidates from diverse undergraduate backgrounds in science, thereby strengthening postgraduate education and research capabilities in core scientific disciplines across India. By centralizing the selection process, JAM reduces the administrative burden on multiple institutions and ensures a standardized evaluation of applicants' aptitude in subject-specific knowledge and analytical skills.[2][5] The examination's scope covers seven distinct test papers—Biotechnology, Chemistry, Economics, Geology, Mathematics, Mathematical Statistics, and Physics—each tailored to assess undergraduate-level proficiency relevant to the respective postgraduate curricula. JAM scores determine eligibility for approximately 2,300 seats in programs offered by IITs, the Indian Institute of Science (IISc) Bangalore, National Institutes of Technology (NITs), and other Centrally Funded Technical Institutions (CFTIs) such as the Defence Institute of Advanced Technology (DIAT), Indian Institute of Engineering Science and Technology (IIEST), and Indian Institutes of Science Education and Research (IISERs). This extensive reach extends to both Indian and foreign nationals, promoting inclusivity while prioritizing candidates based on merit through a common merit list and counseling process.[2][1] Ultimately, JAM supports the broader objective of fostering scientific careers by bridging undergraduate education with advanced research opportunities, with admissions leading to degrees that emphasize rigorous training in theoretical and applied sciences. The test's structure, comprising multiple-choice, multiple-select, and numerical-answer-type questions, evaluates not only factual recall but also problem-solving under timed conditions, aligning with the demands of postgraduate-level study.[5][6]Participating Institutions

Historical Development
Inception (2004–2010)
The Joint Admission Test for Masters (JAM) was initiated in 2004 by the Indian Institutes of Technology (IITs) to consolidate and standardize admissions into postgraduate programs such as two-year M.Sc., joint M.Sc.-Ph.D., M.Sc.-Ph.D. dual degree, and other post-B.Sc. courses, replacing the prior system where each IIT administered separate entrance tests that varied in format and rigor.[12][13] This unified approach aimed to ensure consistent evaluation of candidates' undergraduate-level proficiency in science disciplines while promoting access to advanced research-oriented education at IITs.[14] The first JAM examination occurred in 2004, facilitating admissions for the 2004-05 academic session and establishing the test as an annual event conducted by a rotating organizing IIT on behalf of all participating institutes.[15] In its formative years from 2004 to 2010, JAM focused primarily on core science subjects, serving as a benchmark for assessing analytical and subject-specific skills essential for postgraduate studies.[6] The examination was held offline, with question papers emphasizing objective and subjective components tailored to fields like mathematics, physics, and chemistry, though the exact subject lineup evolved modestly during this period to align with program offerings at the then-seven older IITs (Kharagpur, Bombay, Madras, Kanpur, Delhi, Guwahati, and Roorkee).[15] Admissions through JAM scores were merit-based, with centralized counseling allocating seats based on rank, preferences, and category reservations, thereby reducing redundancy and enhancing efficiency in the selection process.[13] By 2010, JAM had solidified its role in fostering a national talent pool for scientific research, with IIT Guwahati as the organizing institute that year, conducting the test across multiple centers to accommodate growing applicant numbers.[16] This period marked the test's transition from a novel consolidation effort to a reliable gateway, though it remained limited to IITs without yet extending to broader national institutes like the Indian Institute of Science Bangalore, which began participating in later years.[17] The framework emphasized empirical assessment over disparate institutional biases, prioritizing verifiable academic merit to support India's scientific manpower development.[6]Expansion and Reforms (2011–Present)
In 2011, the Joint Admission Test for Masters (JAM) continued its rotational model for organizing institutes among established Indian Institutes of Technology (IITs), with IIT Kanpur serving as the coordinator that year, followed by IIT Delhi in 2012, reflecting a structured approach to distribute administrative responsibilities across the growing network of IITs.[18] This rotation, formalized among seven zonal IITs (Bombay, Delhi, Kanpur, Guwahati, Kharagpur, Madras, and Roorkee) and later including the Indian Institute of Science (IISc), ensured continuity while accommodating the influx of new IITs established under the Institutes of Technology Act amendments, which expanded the system from five original IITs to 23 by 2025.[2] The addition of newer IITs, such as IIT Mandi, progressively integrated JAM scores for postgraduate admissions; for instance, IIT Mandi adopted JAM for its M.Sc. Chemistry program starting in 2019, broadening access to specialized science programs.[19] A significant reform occurred in 2014 when JAM transitioned from a paper-based test with mixed objective and subjective questions to a fully computer-based test (CBT) featuring only objective multiple-choice questions, multiple select questions, and numerical answer types, aimed at enhancing evaluation efficiency, reducing logistical challenges, and standardizing scoring across an increasing number of test-takers and centers.[20] This shift coincided with the exam's offline-to-digital evolution, enabling expansion to more remote test centers and supporting higher participation volumes, with over 70,000 candidates registering by the mid-2010s. The CBT format has remained consistent since, with minor adjustments like randomized question sequencing to prevent malpractices.[21] Post-2015, JAM's scope expanded beyond IITs through integration with the Centralized Counselling for M.Sc./M.Sc. Tech. (CCMN) process, allowing scores to qualify candidates for admissions in Centrally Funded Technical Institutions (CFTIs), including National Institutes of Technology (NITs), starting notably from JAM 2017 onward, which increased available seats in non-IIT programs.[22] By 2025, JAM scores facilitated admissions to over 2,300 seats across IISc, select IITs, NITs, and other CFTIs like the Defence Institute of Advanced Technology (DIAT) and Indian Institutes of Science Education and Research (IISERs), with IIT-specific postgraduate seats exceeding 3,000 annually.[2][23] This reform, driven by government initiatives to democratize access to quality science education, correlated with IIT infrastructure expansions approved in 2025, adding thousands of seats across newer campuses like IIT Bhilai and IIT Jammu, though JAM utilization varies by program and institute.[24] The overall seat matrix has grown approximately threefold since 2011, reflecting causal links between institutional proliferation and demand for standardized postgraduate entry mechanisms.Administration
Conducting Body
The Joint Admission Test for Masters (JAM) is administered collectively by the Indian Institute of Science (IISc) Bangalore and the Indian Institutes of Technology (IITs), functioning as the primary conducting entities responsible for the examination's design, execution, and oversight.[2] [1] This collaborative framework ensures standardized procedures across participating institutions, with admissions coordinated post-exam by individual IITs and IISc based on JAM scores.[3] Each year, one IIT is designated as the organizing institute on a rotational basis to manage operational aspects, including application portals, computer-based test (CBT) logistics at approximately 100-120 centers nationwide, and preliminary result dissemination.[2] [5] This rotation distributes administrative responsibilities and draws on the infrastructural capabilities of different IITs; for example, IIT Delhi served as the organizing institute for JAM 2025, handling registrations from September 2024 and the exam on February 2, 2025, while IIT Bombay assumed the role for JAM 2026, with the test scheduled for February 15, 2026.[4] [3] The organizing IIT collaborates with IISc and other IITs (such as Delhi, Guwahati, Kanpur, Kharagpur, and Madras) for test development and validation, maintaining exam integrity through measures like randomized question sets and secure online platforms.[3] No fixed roster for rotation is publicly mandated, but historical patterns confirm annual shifts among established IITs to prevent overburdening any single campus.[25] This model has sustained JAM's scale, accommodating over 70,000 applicants annually since its expansion.[5]Organizational Process
The organizational process for the Joint Admission Test for Masters (JAM) is overseen by a designated Organizing Institute, selected on a rotational basis from among the Indian Institutes of Technology (IITs) and the Indian Institute of Science (IISc). This institute handles all aspects of exam administration, including scheduling, application management, test conduction, and coordination of admissions for participating Admitting Institutes. For JAM 2026, IIT Bombay serves as the Organizing Institute, managing operations through its GATE-JAM Office.[5] The process begins with the release of an official information brochure outlining exam details, such as subjects, syllabus, eligibility, and timelines, typically in the preceding year. Applications are processed exclusively online via the JAM Online Application Processing System (JOAPS), requiring candidates to register, upload documents (including category certificates for reservations), and complete fee payment electronically between early September and mid-October. Document verification for categories like SC/ST, OBC-NCL, EWS, and PwD extends to late December if needed. Admit cards, containing exam center details, become downloadable from JOAPS approximately two weeks before the test.[5] The examination is administered as a fully computer-based test (CBT) on a single day in mid-February, across seven subjects in two sessions, at around 116 test centers distributed over eight zones in major cities throughout India. Centers are selected to ensure accessibility, with biometric verification (fingerprint and photograph) at entry points for candidate authentication. Proctors enforce a strict code of conduct, prohibiting personal calculators, electronic devices, or communication; scribble pads and virtual calculators are provided on-screen. Question formats include multiple-choice questions (MCQs), multiple select questions (MSQs), and numerical answer type (NAT) questions, with mock tests available prior to the event for familiarization.[5] Following the exam, the Organizing Institute releases provisional answer keys for review, permitting an objection window for candidates to challenge discrepancies, after which final keys and scores are computed. Results, including All India Ranks (AIR), are declared online, enabling qualified candidates to participate in admissions. The institute coordinates centralized admission rounds—typically four, with potential additional rounds for vacant seats—solely for Admitting Institutes like IITs, based on AIR, reservations, and seat availability; direct applications are required for Result Sharing Institutes. Final authority on disputes rests with the Organizing Institute.[5][2]Eligibility and Application
Eligibility Criteria
Candidates must have completed their undergraduate degree or be appearing in the final year of their qualifying undergraduate degree to be eligible to appear for the Joint Admission Test for Masters (JAM).[26][12] This includes candidates pursuing degrees through regular modes, with proof of degree completion required at the time of admission if appearing in the final year.[26] Degrees obtained via distance education do not qualify unless they align with the candidate's final admitting degree and meet institute-specific verification.[26] There is no prescribed minimum percentage or aggregate marks required in the qualifying degree to appear for JAM, though individual admitting institutes impose their own criteria for admission eligibility, often including minimum qualifying marks in relevant subjects.[8] No upper age limit applies to candidates appearing for the examination.[26][12] Eligibility extends to candidates of all nationalities, including foreign nationals, provided they meet the educational qualification standards; however, foreign candidates with non-Indian degrees must adhere to the admission policies of participating institutes, which may require additional equivalence certifications.[26] Candidates holding multiple degrees or pursuing concurrent programs remain eligible as long as the primary qualifying degree satisfies the above conditions.[12]Application Procedure
The application for the Joint Admission Test for Masters (JAM) is conducted exclusively online through the JAM Online Application Processing System (JOAPS) portal accessible via the official JAM website of the organizing IIT.[27] Candidates must submit a single application form; multiple submissions are rejected.[27] The process typically opens in early September and closes in mid-October of the preceding year, with possible extensions for fee payment.[3] To initiate, candidates register on the JOAPS portal by entering their name, a valid personal email address, an active mobile number, and creating a password, after which an Enrolment ID is generated and sent via email or SMS for subsequent logins, often requiring one-time password (OTP) verification.[27] Upon logging in, applicants complete the form by providing personal details such as nationality, category (GEN/EWS/OBC-NCL/SC/ST/PwD), and academic qualifications, selecting one or two test papers (with one designated as primary for potential admission purposes).[27] Required uploads include a recent passport-size color photograph (3.5 cm width × 4.5 cm height, on plain light background, JPEG format not exceeding 100 KB), a scanned signature (black ink on white paper, JPEG up to 100 KB), proof of date of birth (typically Class X marksheet or certificate), and, if claiming reservation, valid category-specific certificates (e.g., OBC-NCL/EWS issued within the last year, SC/ST/PwD as per government norms).[28][29] All documents must meet specified formats and sizes to avoid rejection.[28] Following form completion and uploads, candidates pay the non-refundable fee electronically via net banking, debit/credit card, or other available modes; for one test paper, the fee is ₹1,800 for General/OBC-NCL/EWS categories and ₹900 for SC/ST/PwD/Female candidates, doubling to ₹2,500 and ₹1,250 respectively for two papers.[27] Upon successful payment, a confirmation is emailed, and candidates can download the admit card later using their Enrolment ID; the organizing IIT verifies eligibility during admission, not at application stage.[27] Applicants are advised to monitor the portal and official communications for corrections or withdrawals, limited to specific windows post-submission.[27]Examination Structure
