The full form of NAAC is the National Assessment and Accreditation Council. It was established in September 1994 by UGC in Bangalore for assessing the achievement of the universities and colleges in the country. 

NAAC includes various tasks, such as evaluating performance, assessment, and accreditation of universities in the country. The ultimate goal of NAAC is empowering the resources, continuous improvement, fulfilling objectives, and maximising the capabilities as well as opportunities. 

NAAC was established on the recommendations of National Policy on Education, 1986. This policy addresses the issues of deterioration of quality in education and program of action. The strategic value of introducing this accreditation body is only to increase the quality of education in the country. 

The NAAC grades the institutes on the basis of the absolute grading system. For example: if your institution is between 3.51- 4.00 points, you will get a letter grade A++, and the performance descriptor is accredited. However, if your performance is less than 1.50, you will get a grade of D and the performance descriptor is not accredited. 

The college and the university need to get accredited by the National Assessment and Accreditation Council as getting accredited means getting a stamp which states that the institution provides quality education. 

Some of the examples of the top universities accredited with NAAC accreditation are the University of Hyderabad, Tata Institute of Fundamental Research, Ramakrishna Mission Vivekananda Educational and Research institutes, and more.
