ASNT ACCP Level 2 + Level 3 Path 2026 — Portable NDT Certification Decoded
ASNT ACCP is the third-party portable alternative to SNT-TC-1A — your certification travels between employers. This 2026 guide explains Level 2 + Level 3 requirements, methods covered, exam structure, and when to choose ACCP over SNT-TC-1A.
ASNT ACCP — Third-Party Portable NDT Certification
The ASNT Central Certification Program (ACCP) is ASNT's third-party portable certification scheme — an alternative to SNT-TC-1A guide (the employer-based Recommended Practice). Where SNT-TC-1A leaves the certification with your employer, ACCP issues the card directly to YOU. Change employers? Your ACCP card stays valid. This portability is increasingly the preferred path for inspectors working across multi-site EPC contracts, EPC contractors with global mobility, and senior multi-method Level III consultants.
ACCP vs SNT-TC-1A — Side by Side
| Dimension | SNT-TC-1A | ACCP |
|---|---|---|
| Type | Recommended Practice (RP) | Third-party certification |
| Certifying body | Your employer (using their Written Practice) | ASNT directly |
| Portability | NOT portable — re-cert at new employer | Fully portable — card travels with you |
| Levels available | Level I, II, III | Level II + Level III (no Level I) |
| Written Practice | Required — employer maintains | Not required — ASNT manages |
| Exam administration | Employer-administered | ASNT-administered |
| Recertification | 3-5 years (per employer's Written Practice) | 5 years |
| Cost | Lower (employer-internal exam) | Higher (ASNT exam fee + processing) |
| Industry preference | US refining + petrochem; MENA | Aerospace; multi-site / global EPC; senior multi-method |
ACCP Methods Covered
ACCP Level 2 + Level 3 cover the major NDT methods:
- ultrasonic testing (UT) — pulse-echo, phased-array, TOFD
- radiographic testing (RT) — film + computed + digital
- magnetic particle testing (MT)
- liquid penetrant testing (PT)
- Eddy Current (ET)
- Visual Testing (VT)
- Acoustic Emission (AE) — Level III only
- Infrared / Thermal (IR) — Level III only
- Neutron Radiography (NR) — Level III only, niche
ACCP Level 2 — Requirements (2026)
- Training hours per method (from ASNT ACCP CP-189 Appendix):
- UT — 80 hrs (40 Level I equivalent + 40 Level II)
- RT — 80 hrs (40 + 40)
- MT — 24 hrs
- PT — 24 hrs
- ET — 80 hrs
- VT — 24 hrs
- Experience (months in the method under qualified Level II/III supervision): 9 + 18 months typical (Level I equivalent + Level II)
- Annual near-vision (Jaeger J1) + color-perception (Ishihara) eye test
- Exam: General + Specific + Practical (administered by ASNT)
- Recertification: every 5 years — proof of continuing employment in method + eye test + employer attestation
ACCP Level 3 — Requirements (2026)
- Basic Exam (135 questions, 4 hours): materials science, NDT process fundamentals, quality management, certification ladder. Taken ONCE — covers foundational knowledge applicable to all methods.
- Method Exam (66 questions per method, 2.5 hours each): physics + equipment + technique + interpretation per method. Taken per method certified.
- Specific Exam (optional, employer-based): codes + standards + procedures for your industry. Common: ASME V + API for refining; NAS 410 + Boeing-specific for aerospace; ISO 9712 for international.
- Experience minimum: 4 years (with degree) or 12,600 hours (high-school diploma)
- Recertification: 5 years — by re-exam OR by approved continuing-experience pathway
When to Choose ACCP Over SNT-TC-1A
ACCP wins when:
- You work across multiple employers — contracting, consulting, multi-site EPC. ACCP saves re-cert at every new employer.
- You target aerospace work — most aerospace primes (Boeing, Lockheed, Northrop Grumman, Pratt & Whitney) prefer third-party certification; ACCP fits, though NAS 410 is the aerospace-specific overlay.
- You target European / Global EPC contracts — ACCP is easier to map to ISO 9712 equivalence than SNT-TC-1A.
- You're a senior multi-method Level III — your card stays portable as you move between operator-side and consulting roles.
SNT-TC-1A wins when:
- You work at a single employer long-term (refinery, midstream, OEM) — no portability premium needed
- You're on a tighter budget — SNT-TC-1A is lower cost overall
- You're in US refining + petrochem — SNT-TC-1A is the dominant scheme
How ACCP Relates to API 510 / 570 / 653 + AWS CWI
Different layers. ASNT certification (SNT-TC-1A or ACCP) = METHOD certification (UT, RT, MT, PT, ET, VT). API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Tank Inspector + AWS CWI = INSPECTION + CODE certifications layered on top. A typical senior refining inspector holds: ACCP (or SNT-TC-1A) Level II UT + RT + MT + PT + API 510 + API 570 + (often) AWS CWI.

Frequently Asked Questions
Q1: Can my current SNT-TC-1A Level II be converted to ACCP Level 2?
A: No automatic conversion. Apply through ASNT, submit training + OJT records, take the General + Specific + Practical exams. Training-hour credit is sometimes granted from prior employer Written Practice records, but the exams are required.
Q2: Is ACCP more expensive than SNT-TC-1A?
A: Yes — ACCP carries an ASNT exam fee + processing fee on top of similar training-hour requirements. The portability premium is worth it for multi-employer career paths. Pricing varies by region and scope.
Q3: Does ACCP exist at Level I?
A: No. ACCP is Level 2 + Level 3 only. Level I path is SNT-TC-1A-only (employer-based).
Q4: How does ACCP compare with ISO 9712?
A: Both are third-party portable schemes. ACCP follows ASNT's question bank + training hours; ISO 9712 follows the country's accredited certification body (PCN, COFREND, DGZfP, AINDT, CGSB). Some employers accept ACCP as ISO 9712 equivalent; others require formal ISO 9712 cards. Senior inspectors often hold both.
Q5: Can I hold ACCP and SNT-TC-1A simultaneously?
A: Yes. Many senior inspectors hold ACCP for portability + SNT-TC-1A at their primary employer for cost efficiency.
Q6: How does NAS 410 fit ACCP?
A: NAS 410 is aerospace-specific (US prime contractors); EN 4179 is the European aerospace equivalent. Many aerospace inspectors hold ACCP + NAS 410 (or ACCP + EN 4179). The schemes overlap in training-hour minimums.
Q7: Where can I take the ACCP exam?
A: ASNT-administered, available at ASNT-approved test centres globally. Houston, Dubai, Mumbai, Singapore, London, Toronto are common. ASNT publishes the test-centre directory.
Q8: What's the Atlantis NDT 5-day ACCP UT Level 2 schedule?
A: Day 1-2 — UT physics + equipment + technique; Day 3 — interpretation + acceptance criteria + ASME V Article 4 reference; Day 4 — General + Specific exam prep + mock; Day 5 — Practical exam prep + full timed mock. 96% first-attempt pass. request a free consultation for next cohort.
