• ASNT Level III consulting: Outsourced Level III, SNT-TC-1A written practices, procedure development and approval, and audit support, delivered remotely or on-site.

Training a crew in Canada? Theory is online and primarily self-paced, and practicals run in the Practical NDT simulator and in person at your facility. Where a job specifies CAN/CGSB-48.9712 instead, our courses do not count toward NRCan or CWB certification; see the note below.

ASNT SNT-TC-1A training and certification for Canadian employers

Atlantis NDT trains NDT personnel to ASNT SNT-TC-1A and helps Canadian employers certify them under their own written practice. Courses are led by founder Anoop Rayavarapu, ASNT NDT Level III in UT, RT, MT, PT and VT, and run year-round.

What Atlantis NDT provides

• Level I and Level II training: ASNT SNT-TC-1A Level I and Level II courses in UT, RT, MT, PT and VT, plus PAUT and TOFD courses, for which conventional UT Level II or equivalent UT experience is recommended first. Course hours follow the SNT-TC-1A recommended classroom hours for each method and level.
• Level III exam preparation: Preparation for the ASNT NDT Level III Basic and Method examinations, and for Level III examinations under an employer's written practice.
• Employer certification under your written practice: As your outside-agency Level III, Atlantis NDT's ASNT NDT Level III administers and grades the general, specific and practical examinations in UT, RT, MT, PT and VT, and helps you document each technician's training, experience, vision and examination records so that you can certify them under your written practice.
• Written practice: We write an SNT-TC-1A written practice for your company or review the one you have, so that your training, examinations and certification records follow it.
• ASNT central certification: Exam preparation for candidates applying to ASNT for ASNT NDT Level II (MT, PT, RT, UT, VT) or ASNT NDT Level III, which ASNT examines and certifies.

Who certifies

• Under SNT-TC-1A. Your employer certifies you, under its own written practice. The certification stays with that employer; a new employer recertifies you under its written practice.
• Under ASNT central certification. ASNT examines and certifies you for ASNT NDT Level II or ASNT NDT Level III, and the certificate is yours.
• Atlantis NDT. Trains you and, as your employer's outside-agency Level III, examines you and prepares the certification records. A course on its own never certifies anyone.

Who it is for

Employers whose customers, contracts or codes specify ASNT SNT-TC-1A or another employer-based scheme, for example:

• Aerospace and aviation. MRO and manufacturing, where your customer or approval specifies an employer-based scheme such as SNT-TC-1A or NAS 410. Atlantis NDT trains and examines to SNT-TC-1A only and does not run NAS 410 training; NAS 410 Level 3 services are available through an associate who holds NAS 410 Level 3. Transport Canada's advisory circular for approved maintenance organizations lists NAS 410, ATA Specification 105 and CAN/CGSB-48.9712 among its recognized NDT trade standards and does not list SNT-TC-1A, so check your approval first: Transport Canada AC 573-003.
• Maritime and shipbuilding. Shipyards, ship repair and marine service companies whose owner, contract or class requirements accept an SNT-TC-1A written practice.
• Nuclear supply chain. Fabricators and service companies doing nuclear supply-chain and US-code work that specifies SNT-TC-1A. This is not a route into in-service inspection at Canadian CANDU stations, where the licensee's inspection program sets the certification its NDT personnel must hold.
• Oil, gas and pipelines. Contractors and fabricators on US-owned or cross-border work, and crews that rotate between Canadian and US sites, where the client or code asks for SNT-TC-1A.

How the training runs

Courses run year-round and enrolment is open all year. Theory is online and primarily self-paced, with access from the moment you enrol and Level III support for questions. Practical training runs in the Practical NDT simulator and in person at your facility, where the practical examination is taken on real specimens. Atlantis NDT has no training centre in Canada.

If your job specifies CAN/CGSB-48.9712

CAN/CGSB-48.9712, an identical adoption of ISO 9712, is Canada's national standard for NDT personnel certification and a third-party scheme. A job that specifies it needs a certificate from the Natural Resources Canada NDT Certification Body (NRCan NDTCB) or CWB Group, and method training from one of their Recognized Training Organizations (RTOs). Check the job posting, contract or client specification before you choose a course.

Atlantis NDT is not an RTO. Atlantis NDT is not a Recognized Training Organization for NRCan or CWB Group. Our courses do not count toward NRCan or CWB certification, so take CAN/CGSB-48.9712 method training with an RTO.

NRCan or CWB Group. CWB Group states there is no difference in validity, recognition or technical requirements between the two. The NRCan NDTCB requires at least 40% of course time to be practical. NRCan written exams are taken in person at its Authorized Examination Centres; CWB Group offers remote invigilation of written exams.

The CGSB has closed. The Canadian General Standards Board ceased operations on April 1, 2026. It published the standard; it did not issue certificates. CAN/CGSB-48.9712 remains valid through its current cycle, and NRCan says its certification services continue without change.

Level 3 study support. NRCan allows CAN/CGSB-48.9712 Level 3 preparation by courses or by self-study, provided the candidate gives documentary evidence of training acceptable to the NDTCB. The NDTCB decides what it accepts, so confirm with it before you rely on our study support: ask about Level 3 study support.
