The IIT Joint Admission Test for M.Sc. (IIT JAM) is a prestigious entrance examination conducted jointly by the Indian Institutes of Technology (IITs) and the Indian Institute of Science (IISc) for admission to various postgraduate programs, primarily Master of Science (M.Sc.) and integrated Ph.D. programs across IITs and IISc. The exam is typically held once a year, usually in February, and is aimed at assessing candidates' understanding of undergraduate-level science subjects such as Physics, Chemistry, Mathematics, Biological Sciences, and Mathematical Statistics.

IIT JAM is recognized for its rigorous examination format and comprehensive syllabus, which reflects the core concepts covered during the undergraduate studies. The test is structured as a computer-based exam, comprising multiple-choice questions (MCQs), multiple select questions (MSQs), and numerical answer questions (NATs). Candidates are evaluated based on their conceptual knowledge, analytical skills, and problem-solving abilities. Successful candidates can secure admission to various postgraduate programs, including M.Sc., M.Sc.-Ph.D. dual degree programs, and M.Sc. in areas like Environmental Science, Biotechnology, and Geology.

To be eligible for IIT JAM, candidates must have completed their undergraduate degree in a relevant field with a minimum percentage of marks. The exam provides a gateway to pursue advanced studies in esteemed institutions, which are known for their high academic standards and excellent research facilities. Furthermore, IIT JAM is a stepping stone for candidates aspiring to pursue a Ph.D. or a career in research and academia. The results are announced in March, followed by a centralized admission process where candidates can apply for their preferred courses based on their ranks. Overall, IIT JAM plays a crucial role in shaping the academic and professional futures of countless science graduates in India.
