SHL Style Numerical Reasoning Tests

About the SHL numerical reasoning test

SHL numerical tests are designed to be challenging, to help employers select the best candidates from what’s often a competitive pool of applicants.

There are usually 18 questions, all of which require complete focus as it can be complex to choose the correct answer to, and you have very little time to answer each one.

Typically, you’ll be asked to analyse tables, charts and graphs, and demonstrate mathematical skills by working with multiplication, division, fractions, percentages and ratios.

Some types of tests allow the use of a calculator while others don’t, so always check before you start practicing.

SHL assessments exist in both online and offline formats. If you’re taking the test on a computer, you’ll be advised as to whether you’re taking it unsupervised in a location of your choice or supervised by the recruiter. If you progress to a later stage having taken an unsupervised test, it’s likely you’ll have to do a follow-up one in exam conditions.

SHL Verify is used to draw random questions from a database to guard against cheating. It ensures no two candidates get the same test in the hiring process, and helps to make the recruitment process fairer and more objective.

Aptitude tests are typically evaluated on a comparative basis, meaning your performance is assessed in relation to the results of other candidates who took the same test. This comparative scoring system helps employers understand how an individual’s skills stack up against a broader applicant pool, providing a relative measure of aptitude rather than an absolute one.

How to prepare for and pass an SHL numerical test

The best way you can prepare for the SHL numerical reasoning questions is to take as many past sample numerical tests as you can. 

We recommended whole SHL numerical reasoning tests rather than practicing the questions in isolation, as it’s important to practice questions under time pressure to ensure you’re answering each question with both the speed and accuracy needed.

Before taking a mock test, ensure you have everything you need: a calculator (only if you will be taking the real test with one), pens and paper, a glass of water, and most importantly — a timer. 

At the start of any test, quickly work out how long you have to answer each question and try to stick to it. If you’re struggling with a particular question, move on to the next and remember to go back to it at the end if you have time.

After you’ve finished a test, it’s essential to go back through your answers and note down any questions you’ve got wrong. This will help you decipher whether you have a particular skill you need to brush up on (e.g. fractions), or if it’s your ability to answer the questions in the allocated time that’s the issue.

Remember that on the actual assessment there isn’t a penalty for answering a question incorrectly, so it’s essential you answer each one, even if you only have enough time for guesswork.
