What Is the SHL Mechanical Comprehension Test?
This mechanical comprehension test is designed by Saville and Holdsworth Limited (SHL), one of the top pre-employment test providers in the world. The SHL Test aims to assess an applicant’s ability to understand mechanical concepts and apply them to different situations and scenarios that can occur within a workplace.
Many employers use these tests as part of their hiring process in order to find the top candidates for graduate schemes, internships, or full-time positions within the company.
During the test, candidates are given 10 to 15 minutes to answer 15 to 18 questions in total. It can be taken online and in person. It is worth noting that some employers may require you to take the test twice (once online and once on location) to ensure your score is genuine. While it is similar to mechanical aptitude tests, it does have some unique key differences.
- Depicts machinery and tools instead of theoretical scenarios
- Each question is in multiple-choice format
- Cannot change already submitted answers
The main goal of this test is to assess one’s understanding of machinery and the many aspects of operational uses, maintenance of machinery, knowledge of basic mechanical principles, and one’s ability to apply that knowledge within certain scenarios in the real world.
The test will be different for every candidate, and the difficulty of the questions is not based on the candidates’ performance. Test takers can answer the SHL mechanical comprehension test only, or with any other test as dictated by recruiters and HR managers.
How Will I Be Assessed?
The best part of the SHL test is that it only counts your correct answers. This means that you will not lose points for wrong answers.
This is true across most SHL tests. No matter the type of test, though, you’ll be answering multiple-choice questions. This makes it even better, you have a decent chance of guessing correctly in such a format.
The point here is that it is crucial to answer every question. You might not know every answer, but you should not leave any item unanswered. Remember, you are not penalised for wrong answers.
So, what happens when you submit your test?
Your results will be compared to a reference group of people that are made with similar characteristics as you. So, you will essentially be scored against thousands of people of the same nationality, age, and education, amongst other factors. You would also be scored against people in the same industry and job level to give your employers a sense of your skills.
Your score will be presented as a percentile. So, when you receive your score, you will see something like “75th percentile.” This would mean that you scored higher than 75 percent of the people within your group, which is a pretty great score.
If you want to progress to the next stage, you will need to get a score that is higher than the other people in your reference group—40 percent higher than their average score. Additionally, if you want the best chance of getting into the next selection stage, you should aim to be at least in the top 20 percent of your group.
Basically, all of this means that your raw score does not matter. How you compare to others is what matters, so look for that percentile score before anything else, and study so that you can perform well in your industry.
What Is Included in the Test?
The SHL mechanical comprehension test focuses on five core topics. The topics are:
Mechanical Devices Interaction
The interaction of parts within machinery is a major focus point of the test. Therefore, questions for this topic will involve various mechanical systems, and you will be required to predict what happens when they function.
Applicants will be asked about subjects such as gear ratio and directionality within machinery. These questions are standard for SHL Mechanical Comprehension Tests.
Force and Torque
This is less common in the SHL Mechanical Comprehension Test than in other assessments. It includes a selection of fundamental mechanical concepts, and understanding them is critical for answering correctly. To perform well, you need to know concepts like the law of the lever, force equilibrium, and other related topics.
These questions focus on subjects and materials pertaining to hydraulics, flow, and the relationship between heat and pressure.
Tools and Equipment
These questions require the applicant to answer questions that apply physical principles to various power tools and shop equipment. In addition, candidates will be required to determine which tools are preferable for specific tasks.
Sample SHL Test Questions
The SHL Mechanical Comprehension Test questions feature actual illustrations of machinery and tools instead of text-describing scenarios. Hence, expect to see many illustrations and diagrams.
Some sample questions you might encounter include:
- What is the maximum weight that this lever could lift?
- In which direction will the white wheel rotate?
- Which shelf has a higher possibility of bending?
- How much force is needed to lift the weight with the pulley?
Have a look at Job Test Prep’s practice plan which features accurate sample tests so you will know exactly what to expect. Their practice plan also includes guidance to teach you the actual principles behind the answers.
How to Pass the SHL Test
Passing the SHL Mechanical Comprehension Test means scoring higher than other people in your group. You do not need to get a perfect score, you only need to perform better than others by a certain percentage. So, to pass the test, the best thing you can do is to begin by brushing up on your basic skills.
You can never predict what questions you might encounter, so knowing the basic skills will help you throughout the test. Of course, that means knowing fractions and ratios and completing lots of practice to get the hang of it.
You likely know how to do these things already, but take time to practice how to do these types of operations again. Spend some time looking at graphs too, so it will be much easier for you to understand them when it comes time to undergo the test.
Remember that this is a timed test, after all, so you do not want to spend a lot of time trying to recall how to work with decimals or read graphs.
This is where you should take the time to complete some practice tests. Job Test Prep has all the practice tests and guides that you will need. Not only will these help you with your basic skills, but taking these tests will help you become familiar with the format of the tests and the types of questions you might encounter.
While it might be tempting to give yourself an extra minute or two to complete the test, you should set a timer and stick to it so that you can get used to completing the test in a set amount of time.
Practice these tests until they are familiar. This means understanding questions that are abstract, layered, or have odd wording and items meant to confuse.
How to Prepare For SHL Mechanical Comprehension Test
Preparation is really important in taking mechanical reasoning tests because of the time limit and the steep competition. One of the best ways to prepare is to familiarise yourself with the test questions, which will give you an edge over the other people within your group. Here are some things to keep in mind while doing your prep work:
- Refresh your memory on some basic math and reading skills that are essential in all standardised tests.
- Create an actual practice plan for yourself. This means creating a plan that focuses on the five common topics that are on your Mechanical Reasoning Test and making sure that you’re familiar with all of them.
- Take the mechanical reasoning practice tests on Job Test Prep, which will show you the questions you need to answer and even provide you with a time limit.
- Remember that it is a short test with only 15 questions to complete in just 10 minutes. So, choose practice tests structured this way so that you get used to questions involving mechanical concepts like levels, gears, and pulleys in such timed conditions.
- Try to work within a time limit and simulate the structure of the test. This will help you learn your skills while hopefully making you feel less nervous about facing the actual test.
Have a look at these test tips which can give you an added edge over other test candidates.
Improve Your Mechanical Knowledge
It is crucial to assess your understanding of technical mechanical elements like levels, springs, pulleys, gears, and electrical circuits and principles like force, motion, and energy. The best tip is to ensure you have existing knowledge of the topic before taking the test.
Check Your Equipment
Before you take the test, it is essential to take the time to check your browser and Internet connection. While you might live in an area where your internet goes out a lot, you should make sure that you can do as much as possible to ensure that this does not happen.
Your next question on the test will load as soon as you finish the previous one, so if your connection is slow or your Internet goes out, you will have to wait for it to come back before your test can continue.
Take as many of those practice tests as possible. It helps to test once or twice, but the more you test, the more comfortable you will be when taking the actual test.
Hone your practice skills. It is not just about gaining knowledge and skills—it is also about feeling confident when you take the test and how well you can recall all the knowledge that you learned.
Take Your Practice Tests Seriously
When you take these practice tests, it is crucial to take them in suitable surroundings. This means sitting somewhere quiet that is free from distractions.
Avoid anything that might make it hard to focus or take your attention, and have everything you would have when you take the test, like scratch paper to help you work out any math.
Pay Attention to the Details
Finally, read all of your questions carefully and pay attention to the details. You will be looking at diagrams, reading charts, and going through different types of text too.
Do not rush through the test because it can be difficult to absorb everything and perform the correct calculation if you go too quickly. While you need to move at a steady pace, remember not to rush.
With the help of Job Test Prep, it is possible to be adequately prepared for the SHL Mechanical Comprehension Test. Create a practice plan that is comprehensive and ensure that you are familiar with all the five core topics that will be tested.
Then, stick to the plan with discipline and you will be able to face the test with confidence and a high chance of success.
