The GAPC v3 to v4.0 transition reduced NBA’s Programme Outcomes from 12 to 11, aligned with the Washington Accord 2021 Review. The shift became operational in NBA’s Revised SAR 2025 format — 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. The most consequential change: old PO6 (The Engineer and Society) and old PO7 (Environment and Sustainability) merged into a single new PO6 “The Engineer and the World”. Old PO8-PO12 then shifted down to become new PO7-PO11. Institutions with SARs prepared under GAPC v3 must migrate PEO/PO/CO architecture, CO-PO mapping, attainment calculations, and all SAR Criterion 3 evidence.
In short: The reduction from 12 to 11 POs is not cosmetic. The merger of old PO6 (Engineer and Society) + old PO7 (Environment and Sustainability) into new PO6 (The Engineer and the World) reflects the Washington Accord 2021 view that societal context and sustainability are not separable from the engineer’s practice. Sustainability simultaneously became more pervasive — woven into new PO3 (Design), new PO4 (Investigation), and new PO2 (Analysis). All institutions with SARs under the old framework must update: PEOs, PO statements, PSOs, every course’s CO-PO mapping, attainment computations, Action Taken Reports, and assessment rubrics. Typical migration timeline: 3-6 months for a single programme, 8-10 weeks if compressed with OBE software support.
Why the change: Washington Accord 2021 Review
The Washington Accord is an international multilateral agreement among engineering accreditation bodies (20+ signatories including ABET in the USA, the Engineering Council in the UK, Engineers Australia, Engineers Canada, JABEE in Japan, and IES in Singapore). It defines what makes engineering qualifications substantially equivalent across signatory countries — enabling graduates from accredited programmes in one country to be recognised in others without re-qualifying.
The Accord conducts periodic reviews of its graduate attributes framework. The 2021 Review updated the framework with three notable shifts: (1) merger of social context and sustainability into a single “Engineer and the World” attribute, recognising they cannot be separated in modern engineering practice; (2) explicit emphasis on Complex Engineering Problems (WP) and Complex Engineering Activities (EA) as the threshold for what makes engineering work professionally distinct; (3) integration of digital literacy across all attributes rather than as a standalone competency.
As a permanent signatory since 13 June 2014, NBA must align its accreditation framework with each Washington Accord revision to maintain Indian engineering degrees’ international equivalence. GAPC v4.0 is NBA’s implementation of the 2021 Review. The transition is not optional for institutions seeking Tier I (autonomous) accreditation, which carries the Washington Accord recognition.
The 12-to-11 PO mapping: old GAPC v3 to new GAPC v4.0
Each old PO maps to a new PO — usually 1:1, sometimes with redefinition, and once via merger. This is the canonical reference table for institutions migrating documents.
| Old GAPC v3 PO | Old Title | → | New GAPC v4.0 PO | New Title | Status |
|---|---|---|---|---|---|
| PO1 | Engineering Knowledge | → | PO1 | Engineering Knowledge | Unchanged |
| PO2 | Problem Analysis | → | PO2 | Problem Analysis | Same name, redefined to require holistic problem consideration |
| PO3 | Design/Development of Solutions | → | PO3 | Design/Development of Solutions | Same name, sustainability woven in explicitly (public health, safety, cultural, societal, environmental) |
| PO4 | Conduct Investigations of Complex Problems | → | PO4 | Conduct Investigations of Complex Problems | Same name, sustainability woven in |
| PO5 | Modern Tool Usage | → | PO5 | Engineering Tool Usage | Slight rename, scope unchanged |
| PO6 | The Engineer and Society | ▼ | PO6 (MERGED) | The Engineer and the World | MAJOR CHANGE. Society + Sustainability merged into a single PO |
| PO7 | Environment and Sustainability | ▲ | |||
| PO8 | Ethics | → | PO7 | Ethics | Expanded scope: now includes human values, diversity and inclusion (beyond pure ethics); shifted down from old PO8 |
| PO9 | Individual and Team Work | → | PO8 | Individual and Collaborative Team Work | Renamed (added “Collaborative”), shifted down (was PO9) |
| PO10 | Communication | → | PO9 | Communication | Same scope, shifted down (was PO10) |
| PO11 | Project Management and Finance | → | PO10 | Project Management and Finance | Same scope, shifted down (was PO11) |
| PO12 | Life-Long Learning | → | PO11 | Life-Long Learning | Same scope, shifted down (was PO12) |
The structural pattern: POs 1-5 keep their numbers and names (with refined definitions). Old PO6 + PO7 merge into new PO6. Then everything from old PO8 onwards shifts down by one position. The numbering shift is the single biggest source of document errors during migration — a course handout that says “CO addresses PO8” means Ethics under GAPC v3 but means Individual and Collaborative Team Work under GAPC v4.0. Every PO number reference in every document needs to be reviewed in context.
Deep-dive: the PO6 merger
🌎 Old PO6 + Old PO7 → New PO6
⚠ Old GAPC v3 PO6
The Engineer and Society
Apply reasoning to assess societal, health, safety, legal, and cultural issues
✅ New GAPC v4.0 PO6
The Engineer and the World
Societal, environmental, cultural, ethical context integrated holistically
⚠ Old GAPC v3 PO7
Environment and Sustainability
Understand impact of engineering solutions in environmental contexts
✅ New GAPC v4.0 PO6
(same as above)
Sustainability + societal awareness inseparable
Why this merger matters: The Washington Accord 2021 view is that an engineer cannot meaningfully address sustainability without addressing societal context, and cannot address societal context without addressing environmental impact. Treating them as two separate POs created artificial documentation silos. Merging them into “The Engineer and the World” signals that this is one holistic competency — assessed integratedly rather than checked off as two separate tick-boxes.
Where did sustainability go?
The single most common misconception during migration: “Old PO7 was Sustainability. New PO7 is Ethics. So sustainability has been removed.” This is wrong. Sustainability did not disappear — it became more pervasive, not less. Under GAPC v4.0, sustainability appears explicitly in four POs:
- New PO3 (Design/Development of Solutions) — solutions must explicitly consider public health, safety, cultural, societal, and environmental factors. Sustainability is now intrinsic to engineering design.
- New PO4 (Conduct Investigations of Complex Problems) — investigations must consider sustainability dimensions and impact assessment.
- New PO2 (Problem Analysis) — problems analysed with holistic awareness, including environmental and social dimensions.
- New PO6 (The Engineer and the World) — the explicit successor to old PO7 along with old PO6.
Course-level remapping: the 5-step process
Every course in the programme’s curriculum needs its CO-PO mapping reviewed and updated. This is typically the longest single workstream in the migration. The systematic 5-step process:
- Inventory. List every course in the curriculum with its existing CO-PO mapping under GAPC v3. Capture the mapping weights (typically 1/2/3 or low/medium/high) for each CO-PO pair. This baseline is the migration starting point.
- Direct translation. For POs unchanged in scope (PO1 Engineering Knowledge, PO5 Engineering Tool Usage, and PO7-PO11 which are shifted-down equivalents of old PO8-PO12), copy the existing mapping to the corresponding new PO. Approximately 60-70% of the existing mapping survives direct translation.
- Sustainability redistribution. For courses previously mapped to old PO7 (Environment and Sustainability), evaluate whether they now contribute to new PO3 (Design), new PO4 (Investigation), new PO2 (Analysis), or new PO6 (Engineer and the World) — typically multiple. A course that taught sustainability through design exercises now likely maps to new PO3 + new PO6.
- Society redistribution. Courses previously mapped to old PO6 (Engineer and Society) now map to new PO6 (Engineer and the World) plus potentially new PO3 (if design involves societal context) and new PO4 (if investigation involves societal context).
- Verification. Ensure no orphan POs (every new PO has at least 3 courses mapping to it at meaningful weight). Ensure no over-mapped POs (a course mapping to all 11 POs at high weight is a red flag for NBA expert teams — suggests gaming or sloppy mapping). Run consistency check: does every PSO trace back to at least one PO via course mappings?
OBE software helps significantly here. Manual remapping in spreadsheets is feasible for small curricula (single discipline, 30-40 courses) but becomes error-prone for multi-discipline institutions. OBE platforms that pre-configure the 11 new POs and support batch CO-PO remapping — with Bloom’s Taxonomy logic for mapping weight validation — compress this from 6-10 weeks of manual work to 2-3 weeks. See Edhitch’s OBE Software for NBA built around the GAPC v4.0 framework.
The 8 SAR areas to update under GAPC v4.0
SAR migration spans 8 distinct workstreams. Each is independent enough that different team members can own different streams, but the streams need to integrate in the final SAR submission.
- PEO statements (Criterion 1). Review whether existing Programme Educational Objectives are consistent with the new 11-PO framework, especially around sustainability, societal awareness, and global engineering practice. Updates typically minor; stakeholder consultation required regardless. Timeline: 2-4 weeks.
- PO statements (Criterion 3). Adopt the 11 new PO statements verbatim per NBA’s GAPC v4.0 specification. Do not paraphrase — the Washington Accord 2021 wording is precise and any deviation creates risk. Timeline: 1 week.
- PSO statements (Criterion 3). Review Programme Specific Outcomes for alignment with new POs. PSOs that referenced old POs by number need updating. Timeline: 2 weeks.
- CO statements for every course. Course Outcomes themselves rarely need formal change — but quality scrutiny is higher under SAR 2025. Generic COs (“Students will understand X”) need to be rewritten as action-oriented (“Students will design X applying Y”). Timeline: 4-6 weeks.
- CO-PO-PSO mapping matrices. The 5-step remapping process above. Typically the longest single stream. Timeline: 6-10 weeks (or 2-3 with OBE software).
- Attainment recomputation. Recompute PO/PSO attainment under the new framework. Direct attainment (assessment-based) and indirect attainment (survey-based). 3-year historical data needs to be re-aggregated. Timeline: 2-3 weeks.
- Action Taken Reports (Criterion 7). Narrative reports linking 3-year attainment trends to specific curriculum changes. Update for new PO numbering and add the “analysis-to-change-to-outcome” traceability that SAR 2025 requires. Timeline: 2-3 weeks.
- Assessment rubrics. Review every rubric used to evaluate student work in courses, projects, capstones. Ensure they assess new PO dimensions — especially Complex Engineering Problems (WP) and Complex Engineering Activities (EA) which SAR 2025 emphasises. Timeline: 4-6 weeks.
Migration audit checklist
Use this checklist 30-60 days before SAR submission to verify the migration is complete. Each item should resolve to “done and verified” before submission.
- PEO statements reviewed and updated where needed for GAPC v4.0 alignment
- 11 PO statements adopted verbatim per NBA GAPC v4.0 specification (no paraphrasing)
- PSO statements updated with corrected PO number references
- Every course CO-PO mapping reviewed under the 5-step remap process
- Attainment recomputed for last 3 years under new framework
- Action Taken Reports written for at least one complete cycle per PO under Criterion 7
- Assessment rubrics updated for new PO dimensions including WP and EA
- SAR Criterion 3 rewritten under new framework with consistency across sections
- Legacy reference audit complete — global search for “12 POs”, “PO12”, “Engineer and Society”, “Environment and Sustainability” across all NBA-relevant documents, each instance resolved
- Course handouts updated with new PO numbering and statements
- Lab manuals updated with corrected PO references in their mapping sections
- Departmental reports updated to reference 11 POs not 12
- Mock SAR review conducted with external accreditation advisor to verify migration consistency
- NBA Coordinator briefed on the migration changes for expert team Q&A
The legacy reference audit is the highest-leverage single check. Migration teams routinely update PEO, PO statements, and the main SAR but forget downstream documents — course handouts that haven’t been printed in a year, lab manuals last revised in 2023, departmental reports cited in annexures. A global document search for the four legacy phrases catches 90% of stale references in one operation.
Frequently asked questions
What is the GAPC v3 to v4.0 transition?
GAPC (Graduate Attributes and Professional Competencies) is the framework defining what an engineering graduate should be able to do. GAPC v3 defined 12 Programme Outcomes — the framework NBA used from approximately 2016 to early 2025. GAPC v4.0 reduced this to 11 Programme Outcomes, aligned with the Washington Accord 2021 Review. The transition became operational in NBA’s Revised SAR 2025 format: 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. Institutions with existing SARs prepared under GAPC v3 need to migrate their PEO/PO/CO architecture, CO-PO mapping matrices, attainment calculations, and all SAR Criterion 3 evidence to the new framework.
Why did NBA move from 12 POs to 11 POs?
The driver is the Washington Accord 2021 Review. The Washington Accord is an international multilateral agreement among engineering accreditation bodies (20+ signatories including ABET in the USA, Engineering Council in the UK, Engineers Australia, Engineers Canada, JABEE in Japan, and IES in Singapore). The Accord defines what makes engineering qualifications substantially equivalent across signatory countries. The 2021 Review updated the graduate attributes framework — including the merger of social context and sustainability into a single “Engineer and the World” attribute. As a permanent signatory since 13 June 2014, NBA must align its accreditation framework with each Accord revision to maintain Indian degrees’ international equivalence. GAPC v4.0 is NBA’s implementation of the 2021 Review.
How do the old 12 POs map to the new 11 POs?
PO1 Engineering Knowledge — unchanged; PO2 Problem Analysis — unchanged in name, redefined to require holistic problem consideration; PO3 Design/Development of Solutions — unchanged in name, redefined to require explicit consideration of public health, safety, cultural, societal, and environmental factors (sustainability woven in); PO4 Conduct Investigations of Complex Problems — unchanged in name, sustainability woven in; PO5 Engineering Tool Usage — unchanged in name (was “Modern Tool Usage”). The big change: old PO6 (The Engineer and Society) and old PO7 (Environment and Sustainability) merged into new PO6 “The Engineer and the World”. Then everything shifted down: old PO8 (Ethics) became new PO7 with expanded scope to include human values, diversity and inclusion; old PO9 (Individual and Team Work) became new PO8 “Individual and Collaborative Team Work”; old PO10 (Communication) became new PO9; old PO11 (Project Management and Finance) became new PO10; old PO12 (Life-Long Learning) became new PO11.
What happened to sustainability after the merger?
Sustainability did not disappear — it became more pervasive. Under GAPC v3, sustainability was a single PO (old PO7: Environment and Sustainability). Under GAPC v4.0, sustainability is woven into three POs: new PO3 (Design — solutions must consider environmental and societal impact), new PO4 (Investigation — sustainability-aware research methodology), and new PO2 (Analysis — problems analysed with holistic awareness including environmental and social dimensions). Plus the new PO6 (The Engineer and the World) explicitly covers sustainability in its merged scope. The strategic implication: sustainability evidence in SAR Criterion 3 now needs to span multiple courses and multiple POs, not just a single “Environmental Studies” module.
What needs to be updated in the SAR under GAPC v4.0?
Comprehensive update required across multiple SAR sections. (1) PEO statements (Criterion 1) — review whether existing PEOs are consistent with the new 11-PO framework, especially around sustainability and societal awareness; (2) PO statements (Criterion 3) — adopt the 11 new PO statements verbatim per NBA’s GAPC v4.0 specification; (3) PSO statements (Criterion 3) — review for alignment with new POs; (4) CO statements for every course — review for currency, no formal change required but quality scrutiny higher; (5) CO-PO mapping matrices — recompute all matrices since POs have changed; (6) PO/PSO attainment calculations — recompute with new framework; (7) Action Taken Reports (Criterion 7) — narrative reports linking 3-year attainment trends to curriculum changes need updating for new PO numbering; (8) Assessment rubrics — review evaluation criteria to ensure they assess new PO dimensions especially WP and EA.
How do you remap existing courses to the new POs?
Course-level remapping follows a 5-step process. Step 1 — Inventory: list every course in the curriculum with its existing CO-PO mapping under GAPC v3. Step 2 — Direct translation: for POs unchanged in scope (PO1, PO5, ethics, communication, project management, life-long learning), copy the existing mapping to the corresponding new PO. Step 3 — Sustainability redistribution: for courses previously mapped to old PO7 (Environment and Sustainability), evaluate whether they now contribute to new PO3 (Design), new PO4 (Investigation), new PO2 (Analysis), or new PO6 (Engineer and the World) — typically multiple. Step 4 — Society redistribution: courses previously mapped to old PO6 (Engineer and Society) now map to new PO6 (Engineer and the World) plus potentially new PO3, new PO4. Step 5 — Verification: ensure no orphan POs (every new PO has at least 3 courses mapping to it at meaningful weight) and no over-mapped POs (a course mapping to all 11 POs is a red flag for NBA expert teams).
Is there risk in leaving old 12-PO references in updated documents?
Yes. NBA expert teams under the Revised SAR 2025 are explicitly looking for framework consistency. References to old PO6 (Engineer and Society) or old PO7 (Environment and Sustainability) in updated SAR documents are immediate red flags — they indicate the institution either has incomplete migration or is reusing legacy templates without proper review. Common slip-up locations: course handouts that list “CO addresses PO6 (Engineer and Society)” where PO6 is now “The Engineer and the World”; lab manuals referencing 12 POs in their mapping section; assessment rubrics evaluating 12 PO attainment; departmental reports citing “all 12 POs achieved”. Migration audit must include a global search for “12 POs”, “PO12”, “Engineer and Society”, “Environment and Sustainability” across all NBA-relevant documents, with each instance updated or removed.
How long does the GAPC v3 to v4.0 migration typically take?
Full migration for a single engineering programme typically takes 3 to 6 months when handled systematically. PEO/PO/PSO statement updates take 2-4 weeks (mostly stakeholder consultation rather than drafting time). Course-level CO-PO remapping across all courses in the programme takes 6-10 weeks depending on programme size — typically the longest single workstream. Attainment recomputation under new framework takes 2-3 weeks once mapping is finalised. Assessment rubric updates take 4-6 weeks. SAR Criterion 3 rewrite under the new framework takes 3-4 weeks. Action Taken Report updates for Criterion 7 take 2-3 weeks. With dedicated NBA Coordinator time and OBE software supporting the migration, this can compress to 8-10 weeks. Institutions attempting migration in the last 60 days before SAR submission typically produce inconsistent documents that surface in pre-qualifier or expert team visits.
How does Edhitch support GAPC v4.0 migration?
Edhitch supports Indian engineering institutions migrating from GAPC v3 to GAPC v4.0: PEO/PO/PSO statement review and update workshops, OBE software implementation with the 11 new POs pre-configured, course-level CO-PO remapping using Bloom’s Taxonomy logic, attainment recomputation under new framework, Action Taken Report updates for Criterion 7, SAR Criterion 3 rewrite under new framework, document migration audit (the legacy-reference search), assessment rubric updates for WP and EA dimensions, and integrated NBA + NAAC + NIRF data architecture alignment so the migration improves all three frameworks simultaneously. 12 years of accreditation advisory experience, 100+ institutions served, 9,000+ faculty trained.
