All India Institutes of Medical Sciences

[3] In 2003, the government of India announced the Pradhan Mantri Swasthya Suraksha Yojana (PMSSY) initiative which aimed at "correcting regional imbalances in the availability of affordable/reliable tertiary healthcare services".

[6] Though the announcement was made in 2003 during Atal Bihari Vajpayee's tenure, the project was delayed owing to the power shift at the centre.

The All India Institute of Medical Sciences (Amendment) Bill, 2012 was introduced in the Lok Sabha on 27 August 2012 in order to replace that Ordinance.

[10] It also conferred the power to establish other AIIMS-like institutes by gazette notification and give them equal status.

[7][12] PMSSY was officially launched in March 2006 and six AIIMS-like medical institutes were announced for under-served states in Patna, Raipur, Bhubaneswar, Bhopal, Jodhpur and Rishikesh.

[17][18][circular reference] In July 2014,[19] in the budget speech for 2014–15,[5] the Minister of Finance Arun Jaitley announced a budget of ₹500 crore (equivalent to ₹799 crore or US$92 million in 2023) for setting up four new AIIMS, in Andhra Pradesh, West Bengal, the Vidarbha region of Maharashtra and the Purvanchal region in Uttar Pradesh.

[22][23] On 28 February 2015, in the 2015–2016 budget speech, Jaitley announced five more AIIMS, in Jammu & Kashmir, Himachal Pradesh, Punjab, Assam and Tamil Nadu and an "AIIMS-like" institute in Bihar.

In December 2018 the government has approved and assigned partial funds for the AIIMS in Madurai,[30] and a foundation stone was set in January 2019 And Not Yet Started Construction Till 2024(Next Election Came).

[41] On 1 February 2019, in the presentation of the interim budget for 2019–2020, Piyush Goyal, who was given temporary charge of the Minister of Finance a week earlier,[42] announced an AIIMS in Haryana.

[44] On 1 March 2022, PM Narendra Modi announced an AIIMS for the state of Manipur under the Atmanirbhar Bharat Scheme.

[47] AIIMS (New Delhi) was originally established as a super-specialty tertiary care centre with primary emphasis on research and specialized training facilities.

As per the latest official notification released by the Ministry of Health and Family Welfare, AIIMS, JIPMER -Puducherry, PGIMER -Chandigarh & all INIs (Institutes of National Importance) were directed to not conduct any Undergraduate entrance exams from 2020 onwards.

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.
