ASSE Backflow

ASSE Backflow is a portable industry credential issued by ASSE International — plumbing-industry certifier for backflow prevention. It is recognised by employers wherever the trade is practised, independent of the school that trained you.

It proves that the holder has been examined against a published standard — knowledge on a written exam and, in most cases, an observed practical performance — and has met the standard of ASSE International.

At VoTechWorks the credential is earned inside the programs that carry it (Plumbing & Pipefitting): the universal core, one competency course per curriculum area with a written exam, an observed skills demonstration and a signed log each, a capstone, an externship, then exam preparation and the credential exam itself, sat at the school's authorized testing center or the body's own site.

It leads to entry-level employment in Building & Construction, counts toward the next credential on the stackable pathway, and is the first line on the résumé an employer reads.

Most industry credentials renew every 2–5 years by continuing education or re-test; NCCER and AWS records stay on the registry.
