These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: How long must employers retain completed I-9 forms for a terminated employee?
Answer: A. 1 year after termination or 3 years after date of hire, whichever is later
Explanation:
A is correct. Federal rules say an employer keeps a completed Form I-9 for 3 years after the date of hire or 1 year after employment ends, whichever date is later. To work it out, calculate both dates and keep the form until the later one.
Rule to remember: for an I-9, compare hire plus 3 years with termination plus 1 year, and keep the form until the later date.
Question: According to the International Building Code, which of the required building inspections is made just after the roof deck or sheathing is installed?
Answer: A. Frame Inspection
Explanation:
A is correct. Under the International Building Code, the frame inspection is made after the roof deck or sheathing, all framing, fireblocking and bracing are in place, and before that work is covered up. The inspector checks the whole structural frame, roof sheathing included.
Rule to remember: the frame inspection happens when the frame is fully built, sheathing included, but still exposed. In an open-book exam, confirm the sequence in the code's inspection section.
Question: What is the minimum slope required for a roof with asphalt shingles to ensure proper drainage?
Answer: B. 3%
Explanation:
Our key marks B, but check this one against the code. The idea behind the question is sound. Asphalt shingles overlap and depend on gravity, so the roof needs enough slope for water to run off before it can work back under the laps. Of the options, 1% is close to flat and is the weakest choice, while 3%, 5% and 7% get steeper in turn. The International Building Code, however, gives the minimum slope for asphalt shingles as a rise-over-run ratio, and that minimum is steeper than every option listed here. The code also requires extra underlayment at the low end of the allowed range.
Rule to remember: the code sets a minimum slope for each roof covering in its roof assemblies chapter. In an open-book exam, look up the covering type and convert the ratio before you answer.
Start with the official material. After NASCLA approves your application, download the PSI candidate bulletin. Read the content outline and the list of approved references. The exam is open book, so the skill being tested is finding answers in those references, not memorising them.
Learn your books. Get the references the bulletin lists and tab them by content area: concrete, wood, roofing, inspections, contracts, safety. Practise turning to a table or section without hunting for it.
Drill by topic. Work through our construction technology set for the trade areas. Then use the safety, contracts, business law, finance, insurance, labor law and lien sets for the business side. On every question you miss, find the rule in your reference, not just in our explanation, and write down where it sits.
Practise pacing. You have 330 minutes for 115 questions. Do timed blocks so you learn when to look something up and when to answer and move on. Flag the slow ones and come back to them.
Before test day. Check your state board's requirements, confirm your PSI booking, and remember that your $130 exam fee and your 3 attempts both run on a 1-year clock.
