The National Assessment and Accreditation Council (NAAC) was initially formed as an autonomous body to assess and accreditate all higher education institutes in India for quality sustenance and quality improvement of higher education, under certain parameters. It is being presently monitored by MHRD, the Government of India, keeping its autonomous status unchanged. The College hosted the NAAC Peer Team visit for the first time on 2nd and 3rd August 2005, for its assessment and accreditation, under Dr. Bulbul Thakur, the then Coordinator of the NAAC Committee. The College was accredited by NAAC with Grade B++ and scored 83%. Subsequently, after the 1st assessment, the NAAC emphasized the establishment of an Internal Quality Assurance Cell (IQAC) as a post-accreditation quality sustenance activity.

The primary aim of IQAC is to develop a system for conscious, consistent and catalytic action to improve the academic and administrative performance of the institution. IQAC ensures continuous improvement in the operation of the institution as also accountability among the stakeholders.

The functions of IQAC are:

• Development and application of quality benchmarks/ parameters for the various academic activities of the institution.
• Dissemination of information on the various quality parameters of higher education.
• Organization of workshops, seminars on quality-related themes and promotion of quality circles.
• Documentation of the various programmes/activities leading to quality improvement.
• Preparation of the Annual Quality Assurance Report (AQAR) to be submitted to NAAC based on the quality parameters.

Accordingly, an Internal Quality Assurance Cell (IQAC) was formally constituted with Dr. Kuntal Mukhopadhyay, the then Head of the Department of Political Science, as coordinator in 2006. Thereafter, Dr. Sanjukta Bhattacharyya, Associate Professor of Philosophy, took over the charge as coordinator, IQAC of Raja Peary Mohan College. The College proceeded for re-accreditation by NAAC for the 2nd phase under the coordinatorship of Dr. Sanjukta Bhattacharyya. The re-accreditation was conducted by NAAC from 10th-12th September 2014 and according to the new methodology the College was awarded Grade B and CGPA Score 2.70 on the 4-point scale. So the college was selected to receive RUSA Grant from the Central Government. Currently, Dr. Sanjukta Bhattacharyya, Associate Professor of Philosophy is the co-ordinator of IQAC of Raja Peary Mohan College. Dr. Krishnanka Shekhar Gayen, Assistant Professor of Chemistry is the assistant coordinator.
