About the NCCER Pipelayer Exam
The NCCER Pipelayer Level 1 (2nd Edition) credential validates the knowledge and skills required to install underground utility pipe for water, wastewater, storm drainage, and gas service. The curriculum covers OSHA Subpart P trench safety, soil classification, pipe materials (PVC, HDPE, ductile iron, concrete), bedding and foundation stabilization, elevations and grades, pipe joining methods, and pressure and leakage testing. Graduates work for utility contractors, municipalities, and underground construction firms.

Frequently Asked Questions
What does the NCCER Pipelayer Level 1 program cover?
The NCCER Pipelayer Level 1 (2nd Edition) program is 187.5 total hours across 9 modules: jobsite safety, tools and equipment, rigging and pipe delivery, pipe cutting, gaskets and joints, introduction to elevations, trench safety, foundation stabilization and bedding, and pipe testing. It prepares workers to install water, sewer, storm drain, and gas utility pipe safely and to code.
How is the NCCER Pipelayer exam structured?
There is no single comprehensive Pipelayer exam. Instead, each of the 9 modules has its own computer-based knowledge test (typically 25-40 questions, 30-90 minutes), administered at an NCCER-accredited training center. You must pass each module at 70% or higher to earn the Level 1 craft completion credential.
What is the difference between a pipelayer and a pipefitter?
Pipelayers install underground utility pipe (water, sewer, storm, gas) in open-cut or trenchless excavations, focusing on trench safety, bedding, and bell-and-spigot or fusion joints. Pipefitters install above-ground industrial and process piping in refineries, plants, and buildings, focusing on threaded, flanged, and welded connections to ASME B31 codes. Both are separate NCCER craft certifications.
Do I need OSHA 10 or OSHA 30 to be a pipelayer?
OSHA training is not a federal requirement to enroll, but many states, utilities, and contractors require OSHA 10-hour (entry-level) or OSHA 30-hour (supervisory) construction safety cards. NCCER Pipelayer Level 1 covers trench safety in depth, including 29 CFR 1926 Subpart P, soil classification, and competent-person responsibilities.
Are NCCER Pipelayer credentials recognized in all 50 states?
Yes. All NCCER credentials register in the national NCCER Registry and are recognized by utility contractors, municipalities, and DOL-registered apprenticeship programs across all 50 states. This portability is especially valuable for pipelayers who travel to large utility and pipeline projects.
How long does it take to become a journey-level pipelayer?
Journey-level pipelayers typically complete a 2-4 year apprenticeship combining 2,000-4,000 hours of on-the-job training with classroom instruction. NCCER Pipelayer Level 1 is the foundational year of that training and is often followed by additional advanced underground utility, equipment operator, or pipeline-specific training.
