What is the Wiesen Test of Mechanical Aptitude?

The Wiesen Test of Mechanical Aptitude (WTMA) is a short and very popular mechanical aptitude test. The test contains 60 multiple-choice questions to be answered in 30 minutes.

This mechanical test covers all of the basic topics of mechanics such as forces, levers, velocity, fluids, etc.

The WTMA test was created by Criteria Corp., the company that administers one of the world's most common pre-employment tests - the CCAT.

What Is a Mechanical Aptitude Test?

The mechanical aptitude test, also named mechanical comprehension test, assesses your ability to understand basic physical principles and apply them to various scenarios.

The questions in these mechanical aptitude tests will usually contain one or more images and a multiple-choice question with 3-4 possible answers. In the vast majority of cases, no calculation is required to solve the question, rather common sense and some previous knowledge of very basic physics.

What Does the Wiesen Test of Mechanical Aptitude Look Like?

Each of the 60 questions on the Wiesen Test is formatted in the following manner: 

Wiesen Test of Mechanical Aptitude Sample Question

The questions on the Wiesen Mechanical Aptitude Test deal mainly with the following topics:

Topic Sub-Topics
Force & Torque
  • Levers
  • Force Equilibrium
  • Buoyancy
  • Hydraulics
  • Acceleration
  • Gravity
  • Rotation
Wheels & Pulleys  

You may find some sample questions further down the page.

What Score Do You Need to Pass the Wiesen Test of Mechanical Aptitude?

The answer depends mostly on the position to which you applied. Here are the common passing scores for various professions:

Job Title Passing Score (Out of 60)
Electrician 47
Forklift Operator 44
Manufacturing and Production 43
Materials Handler 40
Mechanic / Maintenance 46
Oil Services Worker 45
Sales 46
Service Technician 46
Utility Worker 42
Warehouse 46

However, you should remember that this is the lowest acceptable raw score for the position. In the end, you will need to compete with other applicants for your position, and only those with the highest score will move on to the next stage of the hiring process.

What Are the Main Challenges of the Wiesen Technical Assessment?

The Wiesen Test of Mechanical Aptitude has several characteristics that make it especially challenging for test-takers. Take a look at them, and I will do my best to explain how to overcome each.

#1 – Little Time to Prepare

That is one of the main challenges of Wiesen test-takers. From our experience, manycandidates are given a very narrow window of opportunity to take it – 2-3 days tops.

So to make sure you are able to prepare on such a short notice, your practice must be focused and effective.

#2 – A Variety of Questions

The questions on the Wiesen Test can be highly creative and cover a virtually infinite set of subjects. From pots to fishing rods, broomsticks to toasters, and towels to stools, every object imaginable is a question inspiration.

That makes it nearly impossible to memorize scenarios and increases stress and uncertainty.

#3 – The Trap of Intuition

The WTMA test tends to incorporate everyday objects in its questions like furniture, home appliances, and working tools.

Although helpful in many cases, that strategy also tends to create a false feeling of familiarity among test-takers, who give an intuition-based answer and often go wrong.

Take a look at this Wiesen test sample question:

Wiesen Test of Mechanical Aptitude Sample Question 1


Reveal the Answer

This question is a classic case of the trap of intuition.

Kettle B is higher and has a larger volume and initially seems as if it can contain more water. However, the kettle can only contain water to the height of the spout before it starts pouring out. The spout at kettle B is shorter, and the total water height can be lower than in kettle A.

How to Pass the Wiesen Test of Mechanical Aptitude in Less than 3 Days of Practice?

To get well prepared for the Wiesen Mechanical Test, you must address the three challenges I have mentioned above:

  • Little time to prepare
  • Variety of questions
  • Trap of Intuition

Let’s tackle each of them:


#1 – Practice Effectively to Overcome the Short Preparation Time

If you were given more than a few days to prepare, jump ahead to section #2.

However, if you are one of those candidates who are forced to take the Wiesen Test of Mechanical Aptitude on a very tight schedule, here’s your 3-day plan to ace the test:


Day 1 – Diagnostic Test and Big Topics

The first thing you will need to do is to understand your weakest areas, so your practice is personalized and effective. You should also correlate it with “big topics” (such as mechanical concepts and mechanical principles that are more common on the Wiesen Test) and “small Topics” (less common).

That Is What You'll Do:

For that, you will take a 45-question, 22-minute Wiesen Diagnostic Test.

You will then start practicing the big topics, based on your performance:

  • Force and Torque
  • Velocity - Acceleration and Gravity
  • Optics, Acoustics and Thermodynamics

Here’s a section of the personalized test report you will get once you complete the test. This report will allow you to focus your effort in these areas.

Day 2 – More Big Topics and Some Small Ones

This day will focus on taking practice tests by the subject.

That Is What You'll Do:

You will keep practicing the big topics, as well as smaller topics like:

  • Velocity - Rotation
  • Wheels
  • Pulleys

Make sure to thoroughly read the Mechanical Aptitude Study Guide that accompanies the practice tests. As always, focus on the areas you found yourself weaker on in the diagnostic test, e.g. levers, fluids, etc.


Day 3 – Complete the Practice and Take a Full-Length Simulation

The day before the exam is intended to complete the practice tests, and most importantly, take a full-length simulation of the Wiesen Test of Mechanical Aptitude.

That Is What You'll Do:

You will go over additional practice tests (as much as time allows), in the smaller areas of the test, such as:

  • Gears
  • Electricity

After you have completed all of the practice tests on the PrepPack, finish by taking a Wiesen Test of Mechanical Aptitude full-length simulation, to get familiar with the test format and time constraints.


#2 and #3 – Learn Physical Principles to Overcome Variety and Intuition Trap

Whenever you encounter a question on the Wiesen test, or any other mechanical aptitude test, you should ask yourself the mother of all questions:

What is the underlying physical principle behind this question?

Asking this simple question every time will help you at solving ANY mechanical aptitude question, even if you’ve never seen it before. It will also help you avoid falling into the trap of intuition, by understanding the physical explanation behind everyday phenomena.

To achieve that, make sure you thoroughly read the explanations for every question, even if you got it right.


Here are two final Wiesen Test sample questions to illustrate the notion of physical concepts:



Wiesen Test of Mechanical Aptitude Sample Question 3


Reveal the Physical Principle

The answer to this question is that both balls will hit the floor at the same time.

The physical principle behind this is that free falling speed does not depend on the mass of the element, and each object falls at the exact same speed.


Now look at this variation of the same principle:

Wiesen Test of Mechanical Aptitude Sample Question 2


The red ball is dropped from the table, whereas the blue ball is pushed forcefully. Which ball will hit the ground first now?

Reveal the Physical Principle

That seems like a completely different question, right? Unlike the previous question, both balls have the same weight, but different trajectories.

However, the physical principle about free falling remains the same – the falling speed of both balls is constant.

It is true that HORIZONTALLY, the blue ball is moving faster, and that's why it will land farther from the table, but VERTICALLY, they are both falling at the exact same speed, so the answer doesn't change.

That is why in this question, too, both balls will hit the floor at the same moment.


To ace the Wiesen Test of Mechanical Aptitude, you need to have a plan. Practice in a focused and extensive manner, and make sure you understand the underlying physical principles behind the questions.

This strategy will allow you to overcome both the short time you have to prepare, as well as the variety and complexity of questions you may be asked.
