Wiesen Test of Mechanical Aptitude (WTMA) Online Preparation, Tips & Free Practice Questions – 2023

Job Assessment Tests

What Is Mechanical Reasoning?

Mechanical reasoning is the ability to solve problems by using technical skills, physical concepts, and mechanical principles. Someone with a high mechanical aptitude would be able to identify the foundations and the underlying notions of a novel situation to formulate a solution.


What Is the Wiesen Test of Mechanical Aptitude?

The Wiesen Test of Mechanical Aptitude, sometimes abbreviated as WTMA, is an assessment that measures a person’s understanding of mechanical concepts. This test is administered to evaluate job seekers interested in positions that require the operation of heavy equipment and machinery. The WTMA is comprised of the following subsets that tediously examine a candidate’s mechanical aptitude:

  • Concepts of Basic Machinery
  • Gravity & Center of Gravity
  • Electricity
  • Heat
  • Structures, Slopes and Planes
  • Movement of Objects
  • Shape & Volume

The Wiesen Test of Mechanical Aptitude will also evaluate maintenance and repair of machinery alongside operation. This test gained popularity among employers in mechanical trades because the WTMA measures potential job performance and future growth in candidates. This is accomplished due to the impartial formatting and structure of the test, which reads at a middle school level and can be taken in Spanish as well.

There are sixty multiple-choice questions on the assessment. The applicant will have half an hour to complete the test. Each question is accompanied by a diagram which illustrates a mechanical principle or hypothetical scenario. The questions following the diagrams may inquire the shape, size, function, or appearance of physical devices and tools customary to mechanical occupations.


How Is the Wiesen Test of Mechanical Aptitude Scored?

The Wiesen Test of Mechanical Aptitude is scored two different ways. Applicants will receive a raw score and a percentile score. The raw score simply tells you how many questions out of sixty you answered correctly. The percentile score compares your performance to the performance of others who have taken the WTMA. A raw score and a percentile score will almost always be two unique numbers.

It is important to note that most employers will weigh the percentile score more heavily than the raw score. This is because it tells the company that you meet, exceed, or fail to meet their standards. The percentile score is based on a scale from 0-100 and is separated into three categories:

  • High Range: Above the 80th percentile
  • Mid-Range: 25th to 80th percentile
  • Low Range: Below the 25th percentile.

The raw score, however, will inform employers of which occupation suits you best. These suggestions will appear in your feedback report. For example, the score you received may tell you that you are better suited to work in a warehouse than to be an electrician.


When Will I Take the Wiesen Mechanical Test?

The Wiesen Test of Mechanical Aptitude is most likely going to be administered during the hiring process. Job seekers who have successfully completed an initial screening will receive the WTMA via email and be asked to complete it within a specified number of days. After a candidate has completed the assessment, they will be notified within a week or two if they have passed the test.

You may also run into the Wiesen Test of Mechanical Aptitude if you are in the process of becoming a vocational student or applying for an apprenticeship. Students will follow the same guidelines as job seekers.

Example 3:



  1. Correct answer: B

    Oil is the correct answer here because it maintains the smoothness of the moving parts. Water and alcohol would evaporate too quickly to be useful for this kind of maintenance.

  2. Correct answer: A

    Path A is the correct path of the planet. This path is symmetric to the one before it (solid line). Path B is not symmetric and Path C suggests that the planet flew off from the orbit, which is not physically possibly when under the force of gravity.

  3. Correct answer: A

    Cone A has the lower center of gravity. This is because most of its mass is location near the ground.


Tips for the Wiesen Test of Mechanical Aptitude

  • Study the main principles – These are important. Every topic on the test has a law or principle that is used. These mostly include classical physics ideas like gravity, acceleration, heat, as well as electricity. It does not have to be complicated. Just read what the laws mean and it should help you understand how to solve the questions.
  • Study the pictures – The questions on the test usually have pictures that you look at. There can be a difference in the pictures. It is important that you see this difference and know what it means. Think about the law or principle for the problem and think about the difference. You should be able to answer the question from there.
  • Answer every question – You do not get penalized for missing a question or marking an incorrect answer. Just like on many other tests, you should give an answer for each question to increase your chance of a high score.
  • Use practice questions and tests – Take a practice test or some practice questions to help you get familiar with the WTMA. You want to be prepared on the day of the exam.
