For millions of students, admission to an IIT represents an opportunity to study in a challenging academic environment, work with advanced technologies and participate in research addressing national and global problems.
History of the IIT System
The development of the IIT system began after Indian independence, when the country required technically trained professionals for industrialisation and national development.
IIT Kharagpur, established in 1951, was the first IIT. It was followed by IIT Bombay, IIT Madras, IIT Kanpur and IIT Delhi. As the demand for high-quality technical education increased, additional IITs were established in different regions.
The IITs are governed by the Institutes of Technology Act, 1961, as amended from time to time. The Act declares them Institutions of National Importance and provides a common legal framework for their governance.
India currently has 23 IITs:
IIT Bhilai
IIT Bhubaneswar

Although the IITs are best known for engineering, their academic activities extend to science, design, management, humanities, social sciences, public policy, architecture, planning and other interdisciplinary fields.
Admission to Undergraduate Programmes
Admission to most undergraduate engineering programmes at the IITs takes place through the Joint Entrance Examination–Advanced, commonly called JEE Advanced.
Students generally qualify through JEE Main before becoming eligible to appear in JEE Advanced, subject to the rules applicable for that admission year. After the declaration of results, eligible candidates participate in the Joint Seat Allocation Authority counselling process.
The usual admission process includes:
Appearing in JEE Main
Satisfying the eligibility conditions for JEE Advanced
Registering for and appearing in JEE Advanced
Obtaining a valid rank
Participating in JoSAA counselling
Selecting preferred institutes and programmes
Receiving a seat according to rank, category, choices and availability
Completing document verification and admission formalities
Eligibility requirements may change. Candidates should consult the latest information on the official JEE Advanced website and the JoSAA portal.
Postgraduate and Doctoral Admissions
The IITs offer numerous postgraduate and research programmes. Admission routes vary according to the programme and institute.
Common admission pathways include:
GATE for many M.Tech. and related postgraduate programmes
JAM for several M.Sc. and postgraduate science programmes
CEED for postgraduate design programmes
CAT for certain management programmes
Institute-level tests and interviews for Ph.D. programmes
Sponsored, part-time and external research categories at selected institutes
A valid examination score does not automatically guarantee admission. Departments may apply additional requirements relating to academic background, interviews, written tests, work experience or research proposals.

These activities allow students to develop leadership, teamwork, communication and organisational skills.
Career Opportunities
IIT graduates work in engineering, research, consulting, finance, management, public administration, higher education and entrepreneurship. Some pursue postgraduate education in India or abroad, while others prepare for civil services or establish start-ups.
Career outcomes depend on many factors, including:
Academic performance
Technical competence
Communication skills
Internships and project experience
Problem-solving ability
Industry conditions
Programme and specialisation
Individual career planning
Admission to an IIT should not be viewed as an automatic guarantee of a high-paying job. Long-term success requires continuous learning, professional discipline and the ability to adapt to technological change.
