NBA accreditation — from the National Board of Accreditation — is India’s statutory programme-level quality recognition for technical education (engineering, pharmacy, management, architecture, hotel management, computer applications). Under GAPC v4.0 (Graduate Attributes and Professional Competencies Version 4.0), NBA aligns with the Washington Accord 2021 Review, assessing programmes against 11 redefined Programme Outcomes using a 10-criterion SAR (Self-Assessment Report) structure totalling 1000 marks. The new format became mandatory for Tier I (autonomous) engineering programmes from January 1, 2025 and for Tier II (affiliated) programmes from January 2025 with a transition window until June 2025.
In short: NBA accreditation operates under GAPC v4.0, aligned with the Washington Accord 2021 Review. The 12 Programme Outcomes from the previous framework (GAPC v3) were reduced to 11 POs — with old PO6 (Engineer and Society) and old PO7 (Environment and Sustainability) merging into the new PO6 “The Engineer and the World”. Programmes are assessed against 10 SAR criteria totalling 1000 marks. NBA has revised the durations: Full Accreditation (6 years) and Accreditation (3 years), replacing the earlier 5-year / 2-year Provisional structure. Tier I uses grade-based per-criterion assessment (Y/C/W/D); Tier II uses aggregate marks (~750/1000 for 6 years, ~600/1000 for 3 years). OBE-linked weightage is approximately 425/1000 marks — meaning a functioning Outcome-Based Education system is not optional under GAPC v4.0. Tier I autonomous programmes carry Washington Accord international recognition; Tier II affiliated programmes do not, but Tier II accounts for ~90% of Indian engineering programmes.
Why GAPC v4.0 matters: the Washington Accord context
The Washington Accord is an international multilateral agreement among accrediting bodies that recognise the substantial equivalence of engineering qualifications. NBA became a permanent signatory on 13 June 2014, joining 20+ signatory countries including the USA (ABET), UK (Engineering Council), Canada, Australia, Japan, Singapore, and others. Under the Accord, an engineering degree from a Tier I NBA-accredited programme is recognised as substantially equivalent to qualifications from other signatory countries — enabling Indian graduates to practise engineering or pursue higher education internationally without re-qualifying.
The Washington Accord 2021 Review updated the graduate attributes framework that all signatory accreditation bodies must align to. NBA’s response was GAPC v4.0 — the most significant restructuring of NBA accreditation in a decade. The reduction from 12 to 11 POs, the merger of Society and Sustainability into “The Engineer and the World”, the explicit emphasis on Complex Engineering Problems, the integration of sustainability into Design and Analysis — these are not arbitrary changes. They mirror what every Washington Accord signatory body is now doing globally. Indian engineering education is being aligned to global standards in 2026 in a way it has not been since 2014.
The 10 NBA SAR criteria + Tier I and Tier II weightages
NBA’s SAR has 10 criteria totalling 1000 marks. The first 7 are programme-level (assessed at the engineering programme being accredited); the last 3 are institute-level (assessed at the institution as a whole). Weightages differ between Tier I (autonomous) and Tier II (affiliated) reflecting different operational scope:
| Criterion | What it covers | Tier I marks | Tier II marks |
|---|---|---|---|
| Programme Level Criteria | |||
| 1. Vision, Mission & PEOs | Departmental vision/mission, Programme Educational Objectives, stakeholder involvement, dissemination | 50 | 60 |
| 2. Curriculum & Teaching-Learning | Curriculum design, syllabus, pedagogy, alignment with PEOs and POs | 100 | 120 |
| 3. Course Outcomes & Programme Outcomes | CO-PO-PSO mapping, attainment computation, the OBE engine of the SAR. Highest programme-level weight under Tier I. | 175 | 120 |
| 4. Students’ Performance | Admission quality, success rate, academic performance, time-to-completion | 100 | 150 |
| 5. Faculty Information & Contributions | Faculty cadre, qualification, retention, research output, professional contribution. Highest overall weight in either tier. | 200 | 200 |
| 6. Facilities & Technical Support | Laboratories, classrooms, equipment, technical staff, safety infrastructure | 80 | 80 |
| 7. Continuous Improvement | PO/PSO attainment analysis, Action Taken Reports, curriculum revision evidence. The Continuous Quality Improvement (CQI) loop. | 75 | 50 |
| Institute Level Criteria | |||
| 8. First Year Academics | Foundation year curriculum, faculty quality, infrastructure for first-year students | 50 | 50 |
| 9. Student Support Systems | Mentoring, career counselling, placement support, grievance redressal, wellbeing | 50 | 50 |
| 10. Governance & Financial Resources | Institutional governance, financial sustainability, resource allocation, audit | 120 | 120 |
| Total | 10 criteria across programme and institute level | 1000 | 1000 |
The Tier I / Tier II weightage difference matters strategically. Tier I weights Criterion 3 (COs/POs) at 175 marks — 17.5% of the total — reflecting the expectation that autonomous programmes demonstrate mature OBE implementation as the price of curriculum freedom. Tier II shifts that weight (120 marks) into Curriculum (120) and Students’ Performance (150), recognising that affiliated programmes have less curriculum control. Tier I also weights Continuous Improvement higher (75 vs 50) — CQI maturity is the operational discipline that justifies autonomy.
The accreditation outcomes: Full Accreditation, Accreditation, Not Accredited
NBA has revised the duration of award — 3 years of Accreditation and 6 years for Full Accreditation, replacing the earlier 2-year Provisional + 5-year Full structure. The assessment framework also differs by tier: Tier I uses grade-based per-criterion assessment (Y/C/W/D), while Tier II uses marks-based aggregate assessment out of 1000.
✅ Full Accreditation
Tier I: Minimum 7 ‘Y’ grades across the 10 criteria, with zero W or D grades. Tier II: ~750/1000 aggregate marks. Washington Accord recognition for Tier I programmes.
⚠ Accreditation
Tier I: Fewer Y grades but no D grades. Tier II: ~600/1000 aggregate marks. Time-bound opportunity to address gaps before re-assessment.
❌ Not Accredited
Below the 3-year threshold on grade compliance (Tier I) or aggregate marks (Tier II). Programme must address gaps and re-apply.
Tier I grading system: Each criterion is graded with Y (Yes) = 75% and above, C (Concern) = 60-75%, W (Weakness) = 40-60%, D (Deficiency) = below 40%. The per-criterion grade matters more than any aggregate — a programme can have strong aggregate performance but a single ‘W’ or ‘D’ grade compromises the Full Accreditation outcome.
The accreditation cycle in practice: assess your standing 6-9 months before submission, identify per-criterion weaknesses, address them systematically, then submit a SAR that defends every claim with on-site verifiable evidence. The expert team visit cross-checks every SAR claim against on-site evidence — SAR-evidence misalignment is the single largest cause of weaker-than-expected outcomes.
The 11 Programme Outcomes under GAPC v4.0
The 11 POs are the graduate attributes every student of an NBA-accredited engineering programme is expected to demonstrate at graduation. Under GAPC v4.0, the count moved from 12 to 11 — with old PO6 (The Engineer and Society) and old PO7 (Environment and Sustainability) merging into the new PO6: The Engineer and the World. Old PO8 through PO12 shifted down to become new PO7 through PO11.
| PO | Programme Outcome | Focus under GAPC v4.0 |
|---|---|---|
| PO1 | Engineering Knowledge | Math, science, engineering fundamentals applied to Complex Engineering Problems |
| PO2 | Problem Analysis | Identify, formulate, and analyse complex problems — with explicit attention to the holistic nature of the problem |
| PO3 | Design / Development of Solutions | Major change. Solutions must explicitly consider public health, safety, cultural, societal, and environmental considerations — sustainability is now intrinsic to Design |
| PO4 | Conduct Investigations of Complex Problems | Research methodology, experimentation, analysis, interpretation of data — with sustainability woven in |
| PO5 | Engineering Tool Usage | Modern engineering tools, software, prediction and modelling techniques. Digital literacy is now emphasised across all POs |
| PO6 NEW | The Engineer and the World | Merged from old PO6 + PO7. Societal context, environmental context, sustainability, and contemporary issues understood and integrated |
| PO7 | Ethics | Was old PO8. Expanded under GAPC v4.0 to include human values, diversity and inclusion beyond pure professional ethics |
| PO8 | Individual and Collaborative Team Work | Was old PO9. Function effectively as an individual, in teams, in diverse settings |
| PO9 | Communication | Was old PO10. Written, oral, technical communication; engineering activities reporting |
| PO10 | Project Management & Finance | Was old PO11. Engineering and management principles applied to projects, multidisciplinary environments |
| PO11 | Life-Long Learning | Was old PO12. Recognise the need for, and engage in, independent and life-long learning |
For the full 12-to-11 transition story including which old courses map to which new POs, see Edhitch’s 11 Programme Outcomes (POs) of NBA — GAPC v4.0 Explained.
The 425/1000 OBE weightage: why OBE is non-negotiable under GAPC v4.0
Approximately 425 of the 1000 SAR marks under GAPC v4.0 are directly linked to Outcome-Based Education (OBE) implementation — roughly 42% of the total score. The OBE-linked marks are distributed across multiple criteria:
- Criterion 1 — Vision, Mission, PEOs (50 marks): PEO definition with stakeholder involvement, dissemination, and review. The top of the OBE hierarchy.
- Criterion 2 — Curriculum & Teaching-Learning (100 marks): Curriculum-outcome alignment, syllabus design that maps to POs.
- Criterion 3 — CO-PO Mapping & Attainment (175 marks for Tier I): The heart of the OBE engine. Course Outcomes defined, CO-PO-PSO mapping matrices, Bloom’s Taxonomy logic, direct and indirect attainment computation. The single largest weighted criterion.
- Criterion 7 — Continuous Improvement (75 marks for Tier I): The CQI loop — PO/PSO attainment data analysed, gaps identified, curriculum revisions documented as Action Taken Reports. The previous-3-years requirement under SAR 2025 makes this rigorous.
The strategic implication: Without a structured, mature OBE system, scoring above the 3-year Accreditation threshold (~600/1000 for Tier II, equivalent grade compliance for Tier I) becomes structurally difficult. Tier I autonomous programmes have a particularly high bar — Full Accreditation (6 years) requires at least 7 Y grades with zero W or D, and the Washington Accord recognition that comes with Tier I depends on demonstrable OBE maturity. OBE is not optional under GAPC v4.0 — it is the substrate of accreditation. For OBE implementation guidance specifically, see Edhitch’s OBE Software for NBA built around the GAPC v4.0 framework.
Continuous Quality Improvement (CQI): the previous-3-years requirement
Under the Revised NBA SAR 2025, Criterion 7 (Continuous Improvement) requires explicit demonstration that PO/PSO attainment data from the previous 3 years was analysed and led to specific curriculum changes. This is the “Action Taken Report” requirement — calculating attainment is only 50% of the job; demonstrating that the data drove decisions is the other 50%.
Concrete example NBA expert teams now expect: “PO5 (Engineering Tool Usage) attainment for the Software Engineering course was 65% in 2023, below the institution’s 70% threshold. Analysis identified Python proficiency as the gap. In 2024, the curriculum was revised to add a 2-credit Python module and 8 lab hours. PO5 attainment in 2025 reached 78%.” This level of traceability across the previous 3 years is what the new SAR format expects under Criterion 7.
What changed in the Revised NBA SAR 2025
The Revised NBA SAR 2025 (aligned with GAPC v4.0 / Washington Accord 2021) introduces several material shifts beyond the 12-to-11 PO change. The seven shifts that matter most operationally:
- 11 POs replace 12. Old PO6 (Society) + old PO7 (Sustainability) merged into new PO6 “The Engineer and the World”. Old PO8-PO12 shifted down to PO7-PO11.
- Sustainability is woven into Design, Investigation, and Analysis. Not a separate PO anymore. Every design exercise must demonstrably consider environmental and societal impact.
- Complex Engineering Problems (WP) and Complex Engineering Activities (EA) require specific evidence. Generic curriculum descriptions no longer suffice — programmes must demonstrate how complexity is addressed in coursework and assessment.
- Reduced weightage on formulaic attainment calculations. More emphasis on assessment quality, diverse assessment methods (research projects, case studies, hands-on lab work, industry-driven assignments).
- Action Taken Reports are mandatory under Criterion 7. Three-year PO/PSO attainment trends must be linked to specific curriculum revisions.
- Industry-Institute Partnership documentation becomes accreditation-relevant: live projects with industrial partners, industry mentor engagement, project funding records.
- Faculty research quality over quantity. Publications in SCI/Scopus-indexed journals are prioritised over paid open-access journals. Retention and cadre ratio scrutinised — high faculty turnover is now a red flag in Criterion 5 (which carries the highest weight at 200 marks).

Tier I vs Tier II: which applies to your institution?
| Dimension | Tier I (Autonomous) | Tier II (Affiliated) |
|---|---|---|
| Who qualifies | IITs, IISc, IIITs, NITs, central/state/private/deemed universities, autonomous engineering colleges with curriculum freedom | Engineering colleges affiliated to a university, without academic autonomy |
| Share of Indian engineering programmes | ~10% | ~90% (the dominant segment) |
| Washington Accord recognition | Yes — international degree equivalence in 20+ signatory countries | No — but NBA accreditation still required for AICTE, NIRF, scheme eligibility, recruiter credibility |
| SAR Criterion 3 (COs/POs) weight | 175 marks — highest at programme level | 120 marks |
| SAR Criterion 4 (Students’ Performance) weight | 100 marks | 150 marks — higher because of less curriculum control |
| SAR Criterion 7 (Continuous Improvement) weight | 75 marks — CQI maturity expected | 50 marks |
| OBE maturity expectation | High — full institutional implementation | Foundational — mature CO-PO mapping minimum |

Integrating NBA with NAAC and NIRF
Engineering colleges typically pursue all three frameworks: NBA for programme-level accreditation under GAPC v4.0, NAAC for institutional accreditation under the Binary Accreditation Framework + MBGL (operative since 10 February 2025), and NIRF for ranking via DCS portal submission. Approximately 68% of data requirements across the three frameworks overlap — faculty profiles, student data, research output, infrastructure, financial data, placement outcomes, and many other inputs feed all three.
The integrated approach treats them as one institutional data architecture serving three frameworks. This is particularly important now that NAAC’s One Nation One Data Platform cross-verifies institutional data via AI validation against AISHE, UGC, and other government databases — inconsistencies between NBA SAR, NAAC SSR, and NIRF DCS submissions are now systematically caught. Colleges that maintain three separate data architectures pay three times in documentation overhead, then risk validation failures during DVV.
The 68% data overlap matters operationally: Faculty cadre, qualifications, research output, programme outcomes, placement data, infrastructure inventory, financial resources, governance evidence — almost all flow into both NBA SAR and NAAC SSR. The strategic move is to build one institutional data architecture once, then surface the appropriate evidence into each framework’s submission template.

Frequently asked questions
What is NBA accreditation under GAPC v4.0?
NBA (National Board of Accreditation) is the statutory body that accredits technical education programmes in India — engineering, pharmacy, management, architecture, hotel management, computer applications. GAPC v4.0 stands for Graduate Attributes and Professional Competencies Version 4.0, the framework NBA adopted to align Indian engineering accreditation with the Washington Accord 2021 Review. Under GAPC v4.0, NBA assesses programmes against 11 redefined Programme Outcomes using a 10-criterion SAR (Self-Assessment Report) structure with 1000 total marks. The new format became mandatory for Tier I (autonomous) engineering programmes from 1 January 2025 and for Tier II (affiliated) programmes from January 2025 with a transition window until June 2025.
What are the 11 Programme Outcomes under GAPC v4.0?
The 11 POs under GAPC v4.0 are: PO1 Engineering Knowledge; PO2 Problem Analysis; PO3 Design/Development of Solutions; PO4 Conduct Investigations of Complex Problems; PO5 Engineering Tool Usage; PO6 The Engineer and the World (NEW — merged from old PO6 Engineer and Society + old PO7 Environment and Sustainability); PO7 Ethics (expanded under GAPC v4.0 to include human values, diversity and inclusion); PO8 Individual and Collaborative Team Work; PO9 Communication; PO10 Project Management and Finance; PO11 Life-Long Learning. This replaced the earlier 12-PO framework (GAPC v3). Sustainability and Ethics are no longer standalone silos — they are now woven into the Design, Investigation, and Analysis POs.
What are the 10 NBA SAR criteria and their weightages?
NBA assesses programmes across 10 criteria totalling 1000 marks. For Tier I (autonomous engineering programmes): Criterion 1 Vision, Mission and PEOs — 50 marks; Criterion 2 Programme Curriculum and Teaching-Learning Processes — 100; Criterion 3 Course Outcomes and Programme Outcomes — 175 (highest at programme level); Criterion 4 Students’ Performance — 100; Criterion 5 Faculty Information and Contributions — 200 (highest overall); Criterion 6 Facilities and Technical Support — 80; Criterion 7 Continuous Improvement — 75; Criterion 8 First Year Academics — 50; Criterion 9 Student Support Systems — 50; Criterion 10 Governance, Institutional Support and Financial Resources — 120. Tier II (affiliated) weightages differ — particularly Criterion 3 (120 instead of 175), Criterion 4 (150 instead of 100), and Criterion 7 (50 instead of 75) — reflecting the different operational autonomy of affiliated programmes.
What are the NBA accreditation outcomes and durations?
NBA has revised the duration of award of accreditation: 3 years of Accreditation and 6 years for Full Accreditation, replacing the earlier practice of 2 years of Provisional Accreditation and 5 years for Full Accreditation. The assessment framework differs by tier. Tier I uses grade-based per-criterion assessment: Y (Yes) = 75% and above, C (Concern) = 60-75%, W (Weakness) = 40-60%, D (Deficiency) = below 40%. Full Accreditation (6 years) for Tier I requires at least 7 Y grades across the 10 criteria with zero W or D grades. Tier II uses marks-based aggregate assessment: approximately 750/1000 marks for Full Accreditation (6 years) and 600/1000 for Accreditation (3 years). For Tier I, the per-criterion grade matters as much as overall performance — a single W or D grade can compromise the Full Accreditation outcome. Programme must address gaps and re-apply if below the 3-year threshold.
What is the 425/1000 OBE weightage in GAPC v4.0?
Approximately 425 of the 1000 SAR marks under GAPC v4.0 are directly linked to Outcome-Based Education (OBE) implementation — distributed across the PEO definition (Criterion 1), CO/PO mapping and attainment (Criterion 3 — the largest single criterion at 175 marks for Tier I), curriculum-outcome alignment (Criterion 2), and Continuous Improvement (Criterion 7). This is roughly 42 percent of the total score. Without a functioning OBE system, scoring above the provisional threshold is structurally difficult. This is why Tier I autonomous programmes — which have full curriculum flexibility — are expected to demonstrate mature OBE implementation; the Washington Accord recognition that comes with Tier I depends on it.
What changed in the new NBA SAR 2025 format?
The Revised NBA SAR 2025 (aligned with GAPC v4.0 / Washington Accord 2021 Review) introduces several material shifts: (1) Programme Outcomes reduced from 12 to 11, with Sustainability and Ethics woven into Design, Investigation, and Analysis POs rather than standalone; (2) Greater emphasis on Complex Engineering Problems (WP) and Complex Engineering Activities (EA) — programmes must provide specific evidence of how curriculum addresses complexity; (3) Reduced weightage on formulaic attainment calculations — more on assessment quality and assessment-process diversity; (4) Sustainability now intrinsic to Design (PO3) — public health, safety, cultural, societal, and environmental considerations must be explicit in design pedagogy; (5) Action Taken Reports required — institutions must demonstrate that PO/PSO attainment data from the previous 3 years was analysed and led to specific curriculum changes; (6) Industry-Institute Partnership documentation — live projects, industry mentors, project funding records become accreditation-relevant evidence.
What is the difference between NBA Tier I and Tier II?
Tier I — autonomous institutions including IITs, IISc, IIITs, NITs, central and state universities, deemed universities, private universities, and autonomous engineering colleges. Tier I programmes are recognised under the Washington Accord — meaning graduates have international degree equivalence in the 20+ signatory countries (USA, UK, Canada, Australia, Japan, and others). Tier I requires mature OBE implementation and curriculum autonomy. Tier II — affiliated engineering colleges (without academic autonomy from the affiliating university). Approximately 90 percent of Indian engineering programmes are Tier II. Tier II accreditation does not carry Washington Accord recognition, but is required for AICTE compliance, NIRF participation, government scheme eligibility, and credibility with industry recruiters. SAR weightages differ slightly between Tier I and Tier II — Tier I weights COs/POs and Continuous Improvement higher (reflecting autonomy expectations); Tier II weights Curriculum and Students’ Performance higher.
How does NBA integrate with NAAC and NIRF?
Approximately 68 percent of data requirements across NBA, NAAC, and NIRF overlap — faculty profiles, student data, research output, infrastructure, financial data, placement outcomes, and many other inputs feed all three frameworks. Engineering colleges typically pursue all three: NBA for programme-level accreditation under GAPC v4.0, NAAC for institutional accreditation under the Binary Accreditation Framework + MBGL (operative since 10 February 2025), and NIRF for ranking (data submission via DCS portal). The integrated approach treats them as one institutional data architecture serving three frameworks — particularly important now that NAAC’s One Nation One Data Platform cross-verifies institutional data via AI validation. Edhitch’s accreditation management software is built around this integrated architecture.
How does Edhitch support NBA accreditation under GAPC v4.0?
Edhitch supports Indian engineering institutions with comprehensive NBA accreditation services under GAPC v4.0: SAR preparation for Tier I and Tier II programmes under the new 2025 format, OBE software implementation (PEO/PO/PSO/CO architecture aligned with the 11 GAPC v4.0 POs), CO-PO-PSO mapping with Bloom’s Taxonomy logic, attainment computation (direct and indirect), gap analysis against the 10 NBA criteria, Continuous Quality Improvement (CQI) cycle setup, Complex Engineering Problems and Complex Engineering Activities evidence documentation, Industry-Institute Partnership documentation, faculty training on GAPC v4.0, and integrated data architecture serving NBA + NAAC (Binary + MBGL) + NIRF simultaneously. 12 years of higher-education accreditation advisory across 100+ institutions, 9,000+ faculty trained, 50+ programmes delivered.
