NAAC vs NBA vs NIRF — What Each One Actually Measures

Who runs it and what it covers

The National Assessment and Accreditation Council (NAAC) was established in 1994, following the National Policy on Education (1986), as an autonomous body under the University Grants Commission (UGC). It is headquartered in Bengaluru. NAAC accredits institutions: universities, autonomous colleges and affiliated colleges across all disciplines, not just engineering. An NAAC outcome therefore describes the college as a whole, not any one department.

The legacy grading framework

Under the Revised Accreditation Framework that most currently accredited colleges were assessed on, an institution submits a Self-Study Report across seven criteria (curricular aspects; teaching-learning and evaluation; research, innovations and extension; infrastructure and learning resources; student support and progression; governance, leadership and management; institutional values and best practices), followed by data validation and a peer-team visit. The result is a Cumulative Grade Point Average on a four-point scale, mapped to a letter grade:

A grade is awarded for a fixed accreditation cycle (five years under this framework), after which the institution applies for the next cycle. The grade sheet published with the certificate shows criterion-wise scores and is more informative than the letter alone.

The reform: binary accreditation and maturity-based graded levels

In January 2024 the Ministry of Education accepted the report of a committee chaired by Dr K. Radhakrishnan that recommended replacing the grade ladder with two stages. In the first, every institution is simply classified as Accredited or Not Accredited against minimum benchmarks (“binary accreditation”), the intent being to bring the large number of un-accredited colleges into the system. In the second, accredited institutions may opt into Maturity-Based Graded Levels (MBGL) from Level 1 to Level 5, where Levels 1 to 4 chart progress towards “Institutions of National Excellence” and Level 5 denotes global excellence. NAAC's consultative workshops in 2024 mapped the old seven criteria to ten new attributes covering curricular design, faculty, infrastructure, finances, learning and teaching, extended curricular engagement, governance, student outcomes, research outcomes and sustainability.

In February 2025 NAAC announced that institutions holding grades under the existing framework would retain their validity until the new Basic (Binary) accreditation and MBGL were formally launched, and that institutions could then choose between the two tracks based on readiness. As of October 2026 the roll-out is still in transition: grades already awarded (A++ to C) remain valid until their stated expiry, and the detailed MBGL methodology continues to be finalised. Treat any “NAAC Level” claim with the same care as a grade claim, and verify it on naac.gov.in.

Who runs it and what it covers

The National Board of Accreditation (NBA) was set up by the All India Council for Technical Education (AICTE) in 1994 and has functioned as an autonomous body since 2010. Unlike NAAC, NBA accredits programmes, not institutions: a college may have NBA accreditation for its B.Tech in Computer Science and not for its B.Tech in Civil Engineering. NBA covers engineering and technology, management, pharmacy, architecture, computer applications, hospitality and related professional programmes at diploma, undergraduate and postgraduate levels. Its process is outcome-based, meaning the evaluation turns on whether graduates demonstrably attain stated programme outcomes, not only on inputs such as faculty counts and laboratories.

Tier-I and Tier-II

NBA runs two tracks. Tier-I applies to autonomous institutions, university departments and institutions of national importance (the IITs, NITs and similar). Tier-II applies to non-autonomous colleges affiliated to a university, which is the category most private engineering colleges in Rajasthan fall into, including those affiliated to RTU, Kota. The criteria are the same for both tiers; the marks allotted to each criterion differ. Accreditation is granted for a fixed term and must be renewed through a fresh application; the term depends on how fully the programme meets the criteria, and the current status of every accredited programme is listed on the NBA website.

Washington Accord

NBA has been a permanent signatory of the Washington Accord since 13 June 2014, after provisional membership from 2007. The Accord is a mutual-recognition agreement among engineering accreditation bodies: undergraduate engineering programmes accredited by one signatory are recognised as substantially equivalent by the others. This recognition applies only to programmes accredited under NBA's Tier-I process. Tier-II accreditation of an affiliated college is a national quality mark; it does not by itself carry Washington Accord recognition. Students planning to work or study abroad should check the tier under which a programme was accredited, not just whether it is “NBA accredited”.

The National Institutional Ranking Framework (NIRF) was approved by the then Ministry of Human Resource Development (now the Ministry of Education) and launched on 29 September 2015; the first rankings were published in 2016. NIRF does not accredit anything. It publishes, every year, an ordered list of institutions in each category (Overall, Universities, Engineering, Management, Pharmacy, Colleges and others), based on data submitted by the institutions themselves plus a perception survey. Participation is voluntary: an institution that does not submit data is simply absent from the list, which is why absence from NIRF is not evidence of poor quality.

Each category is scored on five parameters. For the Engineering category, the published weights are:

Weights differ between categories and can change between editions, so check the framework document for the year you are reading. Because research carries a large weight, NIRF favours large, research-intensive, mostly public institutions; a teaching-focused private college can be a sound B.Tech choice and still rank modestly, or not appear at all.

1. Start with approval and affiliation, which are non-negotiable. For an engineering college, AICTE approval and affiliation to a recognised university (RTU, Kota in Rajasthan) are what make the degree valid. NAAC, NBA and NIRF sit on top of that base. A college can be fully approved and affiliated without any of the three, and still award a legitimate degree.
2. NAAC is the broadest single signal. It tells you an external body has examined the governance, teaching, infrastructure, student support and finances of the whole institution. It is also the signal most often required by third parties: education-loan processing, scholarship schemes and foreign universities evaluating Indian transcripts frequently ask whether the institution is NAAC accredited and at what grade. Read the grade sheet, not only the letter.
3. NBA is the sharpest signal for your branch. If you already know you want Computer Science, an NBA-accredited CSE programme is more specific evidence than an institutional grade. Because NBA is programme-level, always check the status of the exact branch you intend to join on the NBA website, and note the tier. A college advertising “NBA accredited” may hold it for one or two programmes only.
4. NIRF is useful for comparing large institutions, and nearly useless for comparing small ones. Research weight and perception surveys favour established public institutions. For private affiliated colleges, the absence of a NIRF rank is routine and tells you very little either way. Look it up on nirfindia.org if the colleges you are comparing all participate; otherwise rely on NAAC, NBA, placement records and the fee-to-outcome ratio.
5. Beware of conflation. “NAAC A+ accredited and NIRF ranked” are two unrelated claims to verify separately, and “NBA accredited” without a programme name is incomplete. Each body publishes a list; a five-minute check settles any doubt.

Arya College of Engineering (ACE), Jaipur, founded in 2005 as Arya Institute of Engineering & Technology (AIET), holds the NAAC A+ grade. It is AICTE approved, affiliated to Rajasthan Technical University (RTU), Kota, and is part of Arya College. The accreditation certificate, institutional grade sheet, self-study reports and annual quality assurance reports are published openly on the NAAC information page, and the NAAC A+ accreditation guide explains what the grade means for admissions, loans and placements. The college's approval documents are on the AICTE mandatory disclosure page.

Consistent with the advice above, we recommend that applicants verify any college's programme-level NBA status and NIRF participation directly on the official NBA and NIRF websites rather than relying on brochure claims, including ours. For a broader comparison of what to look for, see how to choose an engineering college in Jaipur and the courses offered at ACE. Note that ACE is a separate institution from Arya College of Engineering & IT (ACEIT); accreditation records for the two are held independently.

What is the difference between NAAC, NBA and NIRF?

NAAC accredits a whole institution on quality criteria and works under the UGC. NBA accredits individual programmes such as B.Tech CSE on an outcome-based model and was set up by AICTE. NIRF is not an accreditation; it is the Ministry of Education's annual ranking on five weighted parameters. Accreditation is a grade or pass with a validity period; a ranking is a yearly position in a list.

Is NAAC or NBA better for an engineering college?

They answer different questions. NAAC covers the whole college; NBA covers one programme. The ideal is a NAAC-accredited institution that also holds NBA accreditation for the branch you intend to study. Check the NBA website for any programme's status.

Has NAAC stopped giving A++, A+ and A grades?

NAAC has announced binary accreditation (Accredited / Not Accredited) with an optional Maturity-Based Graded Levels track from Level 1 to Level 5. As of October 2026 the transition is still being rolled out, and grades already awarded under the A++ to D framework remain valid until their expiry. Check naac.gov.in for the current position.

What are the NIRF ranking parameters?

Teaching, Learning and Resources (TLR); Research and Professional Practice (RP); Graduation Outcomes (GO); Outreach and Inclusivity (OI); and Perception (PR). In the Engineering category the published weights are 30, 30, 20, 10 and 10 per cent. Participation is voluntary and the list is released every year.

Does NBA accreditation help with jobs abroad?

It can. NBA has been a permanent Washington Accord signatory since 13 June 2014, so undergraduate engineering programmes accredited under its Tier-I process are recognised as substantially equivalent by other signatory countries. Tier-II accreditation of affiliated colleges is a national quality mark and is not covered by the Accord.

Is Arya College of Engineering Jaipur NAAC accredited?

Yes. ACE Jaipur holds the NAAC A+ grade, is AICTE approved and is affiliated to RTU, Kota. The certificate and grade sheet are on the NAAC information page. For any college's NBA programme status or NIRF participation, check the official NBA and NIRF sites directly.
