All NCCER craft programs begin with the core curriculum, which is required before advancing to any specialty trade module. The core curriculum covers fundamental knowledge every construction professional must demonstrate.
This section covers personal protective equipment (PPE), fall protection systems, electrical safety principles, lockout/tagout (LOTO) procedures, and hazard communication under the GHS system. Expect questions on identifying the right PPE for specific hazards and the steps in a proper LOTO sequence.
You'll need to work with fractions, decimals, percentages, and measurements. Problems may ask you to calculate area, volume, or material quantities — skills used daily on construction sites for estimating and layout.
Questions test identification, safe use, and maintenance of common hand tools as well as power tools including circular saws, angle grinders, and drills. Safe operating procedures and guard usage are frequently tested.
Reading orthographic views, plan views, elevation views, and section views is a core skill. You must understand drawing scales, common symbols, and how to extract dimensions from blueprints.
This module covers sling types (wire rope, chain, and synthetic web slings), load calculation basics, and hand signals used for crane operations. Rigging safety and inspection procedures are also tested.
Electrical Level 1 is one of the most widely taken NCCER specialty modules. Key areas include electrical theory (Ohm's Law, Kirchhoff's voltage and current laws), AC versus DC current characteristics, conductors and insulators, and an introduction to the National Electrical Code (NEC). Hands-on skills tested include conduit bending (90-degree bends, offsets, saddle bends), wire pulling and termination, grounding and bonding principles, and overcurrent protection devices such as fuses and circuit breakers.
Plumbing modules cover pipe material types (copper, PVC, CPVC, PEX, and cast iron), DWV (drain-waste-vent) system principles, fitting types, and soldering and sweating copper pipe. HVAC modules address the refrigeration cycle (compressor, condenser, expansion valve, and evaporator), HVAC tools including manifold gauge sets and vacuum pumps, ductwork types (sheet metal and flexible), and EPA Section 608 refrigerant handling awareness.

Which of the following is NOT a good safety practice when working with power tools?
Answer: A. Always keep your finger on the switch button while carrying a power tool
Keeping your finger on the switch button while carrying a power tool is a dangerous practice because it can lead to accidental activation. An unexpected start-up can cause serious injury to yourself or others, or damage to the tool or workpiece. Always ensure the switch is off and your finger is away from the trigger when transporting tools.
When is it necessary to use a full-body harness and lanyard on a construction site?
Answer: B. When working at heights of 6 feet or more above a lower level in general construction
OSHA requires fall protection, including personal fall arrest systems like harnesses and lanyards, when construction workers are exposed to falls of 6 feet or more to a lower level.
Before you start drilling, make sure the drill bit is ______.
Answer: C. tightened in the chuck
Before drilling, it is crucial to ensure the drill bit is securely tightened in the chuck. A loose bit can fly out during operation, causing serious injury or damage to the workpiece. Proper tightening ensures stability, accuracy, and safe operation of the drill.
Discrimination towards an individual based on race, sex, religion, cultural issues, or language barriers is known as _______.
Answer: D. harassment
Discrimination towards an individual based on protected characteristics like race, sex, religion, cultural issues, or language barriers is legally and ethically defined as harassment. Harassment creates a hostile work environment and is unacceptable, violating workplace policies and often anti-discrimination laws. It undermines respect and equality in the workplace.
