Introduction
The purpose of this assessment is to evaluate a candidate's mastery of the foundational skills required in the construction industry. This examination
covers essential knowledge areas including safety protocols, mathematical applications, tool identification, and technical drawing interpretation. The
structure consists of multiple-choice and scenario-based questions designed to mirror challenges encountered on active jobsites. Candidates are
assessed on their ability to apply theoretical concepts to real-world decision-making, ensuring they possess the necessary competence to maintain a
safe and productive work environment. Emphasis is placed on regulatory compliance, professional ethics, and efficient material handling techniques
necessary for entry-level success in the trades.
SECTION ONE: QUESTIONS 1–100
1. Which of the following is a primary requirement for a person to be considered a "qualified person" regarding safety standards?
A. Has spent at least ten years in the construction industry.
B. Owns the company or is a direct relative of the owner.
🟢 C. Has a recognized degree or professional standing and can solve problems related to the subject matter.
D. Is the oldest person currently working on the specific jobsite.
🔴 RATIONALE: According to OSHA and NCCER standards, a qualified person is someone who, by possession of a recognized degree, certificate,
or professional standing, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter.
2. When using a hand tool, what is the best practice if you find a mushroomed head on a cold chisel?
🟢 A. Do not use the tool and ensure it is ground down to its original shape.
B. Use it with caution by wearing extra thick gloves.
C. Apply lubricant to the head to prevent further cracking.
D. Use a heavier hammer to ensure the strike is effective.
🔴 RATIONALE: A mushroomed head on a striking tool like a chisel can chip off and become a dangerous projectile; it must be repaired by grinding
or replaced before use.
, 3. In the metric system, what is the basic unit of linear measurement?
A. Inch
B. Gram
🟢 C. Meter
D. Liter
🔴 RATIONALE: The meter is the standard unit of length in the metric system, whereas grams measure mass and liters measure volume.
4. A worker is using a power drill and notices the cord is frayed, exposing the copper wire. What is the immediate required action?
A. Wrap the area tightly with black electrical tape.
B. Continue working if the drill still functions properly.
🟢 C. Remove the tool from service and tag it out of use.
D. Ask a supervisor to hold the cord in a specific position while drilling.
🔴 RATIONALE: Any power tool with a damaged cord or casing must be immediately removed from service and tagged "Do Not Use" to prevent
electrical shock or fire.
5. Which type of construction drawing shows the layout of the building on the site, including property lines and utility runs?
A. Floor plan
🟢 B. Site plan
C. Detail drawing
D. Section view
🔴 RATIONALE: The site plan (or plot plan) provides a bird's-eye view of the entire property, showing the location of the building in relation to
boundaries and utilities.
6. What is the risk associated with a "load" that is not properly balanced during a manual lift?
A. It makes the load feel lighter than it actually is.
B. It increases the speed at which the worker can move.
🟢 C. It shifts the center of gravity, increasing the risk of muscle strain or dropping the item.
D. It improves the grip strength of the person carrying the load.
🔴 RATIONALE: An unbalanced load shifts unexpectedly, forcing the body to overcompensate with specific muscle groups, which often leads to
back injuries or loss of control.
