Types of Exam Questions

All Red Seal exam questions are written in multiple-choice format. A multiple-choice question consists of question followed by four possible responses (A, B, C, D). Every question has exactly one correct answer and three incorrect options. They are not misleading or trick questions, but the incorrect options are not always obvious.

There are three types of questions that you will see on Red Seal Exams:

Knowledge and Recall
Procedural and Application
Critical Thinking

Knowledge and Recall

This type of question tests your ability to recall and understand definitions, facts and principles.

For this trade, between 50 and 60% of questions that are this type.

Example of a Knowledge and Recall Question:

Which type of drawings indicate piece numbers for assembly of structural steel buildings?

Architectural.
Mechanical.
Structural.
Erection.

Answer: D

Procedural and Application

This type of question tests your ability to apply your knowledge of procedures to a situation.

For this trade, between 35 and 45% of questions are this type.

Example of a Procedural and Application Question:

What is the procedure for off-loading a trailer of structural steel?

Verify bill of lading, select proper rigging, then place in staging area.
Verify bill of lading, shake out steel, then remove load binders.
Position trailer, place in staging area, then remove load binders.
Position trailer, attach rigging, then calculate weight of steel.

Answer: A

Critical Thinking

This type of question tests your ability to interpret data, solve problems and arrive at valid conclusions.

For this trade, less than 10% of questions are this type.

Example of a Critical Thinking Question:

What length of 3/4-in. bolt is required to fasten a double connection through the web of a column when the beam end connections are 5/8 in. each and the web thickness is 1/2 in.?

3 1/2 in.
3 in.
2 1/5 in.
2 in.

Answer: B
