The All India Institutes of Medical Sciences (AIIMS) is a group of autonomous government public medical universities of higher education under the jurisdiction of Ministry of Health and Family Welfare , Government of India. These institutes have been declared by an Act of Parliament as Institutes of National Importance. AIIMS New Delhi, the forerunner institute, was established in 1956. Since then, 24 more institutes were announced. As of January 2022, nineteen institutes are operating and five more are expected to become operational until 2025. Proposals were made for six more AIIMS.

From 2020 session onwards, all such undergraduate admissions would be taken up only through a single national level examination NEET-UG conducted by NTA (National Testing Agency). Many field experts however criticized this exam unification, specifically with respect to AIIMS (New Delhi), citing the reason that the level of questions in AIIMS-UG entrance exams (for both MBBS & BSc Nursing courses separately) used to be of such a higher & deep logical-conceptual thinking capabilities, that they eventually served a greater advantage for selecting the most desirable students for such scientific courses. And that was something really crucial for the main objectives for which AIIMS (New Delhi) was established, which are cutting-edge research, medical innovations and to demonstrate high standards of medical education to all medical colleges and allied institutions in India.
