NDT Written Practice — ASNT SNT-TC-1A Template

A complete editable Written Practice for an employer's NDT certification program, compliant with ASNT SNT-TC-1A. Customize the scope, methods, levels, training, examinations, certification, recertification, and audit clauses for your organization.

ASNT Recommended Practice SNT-TC-1A is the most widely used framework for employer-based qualification and certification of NDT personnel in North America. The Recommended Practice requires every employer who certifies NDT personnel to maintain a Written Practice document that translates the SNT-TC-1A guidelines into specific employer policy.

Use this template to set up a new Written Practice or to update an existing one to the 2024 edition of SNT-TC-1A. It is structured to satisfy customer audit checks (ASME, API, AWS, NAVSEA) and to provide clear, auditable evidence to a Level III examiner.

Atlantis NDT can develop a fully customized Written Practice tailored to your industry, customer base, and Level III preferences — and supply the supporting forms, training records, and examination banks.

No Level III on staff? Atlantis can also act as your outsourced Level III, an outside agency Level III who approves the written practice and administers examinations under it, while certification stays with you as the employer.

Download the free editable written practice template (DOCX), with no form to fill in. If you would rather have the practice written for you, see written practice development by an ASNT Level III.

Atlantis NDT Level III consultants build, audit, and maintain Written Practice programs for inspection companies, manufacturers, and EPCs.

Filling the template without inheriting its defaults

A Written Practice template is a starting structure, not a compliance document — SNT-TC-1A is a recommended practice precisely so the employer tailors it, and auditors read untouched template defaults as evidence nobody engaged. The sections that demand real decisions: training and experience hours per method and level (state yours, with the basis if they differ from Table 6.3.1), the examination structure and grading, vision requirements and recurrence, interrupted-service rules, and the named Level III under whose authority the practice operates. That last line is the one audits test first — a Written Practice whose Level III cannot describe it is a paper programme.

Revise it like a controlled document: revision history, review cycle, and re-examination implications when requirements tighten. The companies that fail written-practice audits are rarely missing the document; they are missing the connection between the document and what actually happens.

Where this document sits in the wider system

Templates fail as loose files and work as parts of a system: this document should cross-reference the records that feed it and the decisions it feeds, carry a revision history like any controlled document, and live where the whole team retrieves the CURRENT version — not the copy someone improved privately last year. Companies running their inspection operations on a single system of record generate most of these documents from live data rather than filling them by hand; that is the practical difference between managed records and managed paperwork.
