Ironworkers Apprenticeship Test Format and Sample Questions

Let's now gain some insight into the basic structure and format of the Ironworkers Apprenticeship test, which is broken down into three sections: math, reading, and practical applications.



  • Basic Arithmetic – Addition, subtraction, multiplication, division; percentage, decimal, fractions, ratios, angle degrees.
  • High School Algebra – Solving for x in equations and ratios.
  • High School Geometry – Identifying at least 16 geometric shapes; finding perimeter, circumference, area, specified sides; most formulas provided in the exam.
  • Units of Measurement – Finding the appropriate unit of measurement for length, area, temperature, time, speed, cost, weight, volume.
  • Conversion – Using conversion tables to solve written problems.

Mechanical Sample Question 1

A tank with a water level of 1 meter is shown in the diagram below.



A rock with a volume of 1[m3] is thrown into the tank.

The rock is porous (i.e. contains air) in a ratio of 50%.

What will be the new water level?

Correct Answer
Incorrect Answer

First, you need to understand that the rock will displace a volume of water equal to its own volume causing the level of water in the tank to rise.

We will begin by calculating the initial volume of water in the tank:

Vwater = 1[m]*1[m]*2[m] = 2[m3]

The volume of the rock is given: 1[m3]

In addition, it is given that 50% of the rock is air, therefore the actual volume the rock displaces is:

Vrock = 50%*1[m3] = 0.5[m3]

Thus, the total volume of water + rock is equal to 2.5 cubic meters.
We will calculate the new water level according the new total volume in the tank:

Vwater+rock = h[m]*1[m]*2[m] = 2.5[m3]

We will isolate the height and obtain:

h = 1.25 meters.
Therefore, the correct answer is 4.

Mathematics (Algebra - Polynomials) Sample Question

Select the correct option for the following equation:

(p2–1) x (s+1)/(p-1) x 1/(s+1) + p+1 = ?

Correct Answer
Incorrect Answer

Simplify the expression by multiplying and dividing:

(p2–1) x (s+1)/(p-1) x 1/(s+1) + p+1 =

=(p2–1) x (s+1)/(p-1) x (s+1) + p+1 =

=(p2–1)/(p-1) + p+1 = ?

Next, simplify by factoring
(a2 – b2) = (a+b)(a-b):

(p2–1)/(p-1) + p+1 =

= (p+1)(p-1)/(p-1) + p+1 =

= (p+1) + p+1 =

= 2(p+1)

Hence: 3 is the correct option.

Tip: If you chose any other answer, you probably did not reduce the fractions correctly.

Reading Comprehension

This section is in the form of written essays that relate to situations common to ironworkers. To choose the right answer from among the multiple-choice options, you will need to remember details, understanding usage of language, and draw the right conclusions:


Reading Comprehension Sample Question 3

Last year, road fatalities decreased by 9%. According to the latest figures published by the Department of Transportation today, this year has seen the lowest number of deaths in road traffic since records began. However, road deaths are only the tip of the iceberg, because for every death on US roads there are 10 serious injuries such as damage to the brain or spinal cord. Country by country statistics shows that the number of road deaths per year still varies greatly across the US with the countries reporting the lowest number of fatalities being the California, Oregon, Washington, Vermont, and Maine, with only 30 deaths per million inhabitants. Vulnerable road users such as pedestrians, cyclists, motorcyclists, and users in certain age groups, notably the elderly, are particularly affected by serious road injuries.


Which of the following statements is correct?


A) Cyclists should be banned from riding on the roads.
B) More animals are killed by cars than by pedestrians.
C) Road deaths are on the rise in Vermont.
D) There are more serious injuries than deaths.
Correct Answer
Incorrect Answer

Option D is correct. This is what the text states: "for every death... there are 10 serious injuries".



Component Locator

This segment of the test is broken down into pattern questions and component questions. Pattern questions aim to see how well you can locate and identify the most central parts of an item, while component successfully perceiving and reproducing pattern outlines, then you will do well on this segment. Additionally, you will also be provided with different parts of an object to see if you can successfully piece them together for assembly and production.

Odd One Out Sample Sample Question

Choose the figure that does not belong to the sequence...

Correct Answer
Incorrect Answer

The correct answer is (B).

The pattern in this sequence is that the entire circle rotates 90 degrees clockwise with each step. This means that the diagonal line and the small circle across from it both move simultaneously so as to remain directly across from each other.
