No, the Motilal Nehru National Institute of Technology (MNNIT) and the National Institute of Technology (NIT) Allahabad are not the same.
MNNIT Allahabad, which was established in 1961, is one of the 30 NITs (National Institutes of Technology) in India and an Institute of National Importance (INI). It is an autonomous institution, funded jointly by the Ministry of Human Resource Development and the Government of Uttar Pradesh.
NIT Allahabad, on the other hand, is one of the seventeen newly established NITs set up by the Ministry of Human Resource Development in 2010.
Both MNNIT and NIT Allahabad are recognized as institutes of national importance, and are affiliated with the All India Council for Technical Education (AICTE). They both offer technical, management, architecture and pharmacy courses at the undergraduate, postgraduate and doctoral levels.
Although both institutes have the same purpose and offer similar courses, they have different governing bodies, admission criteria and fee structures. So, it is important to know the differences between the two before making any decisions.
