Employers choose to use psychometric testing during their recruitment process to help give a better overall evaluation of candidate’s and their suitability for the job that they’re applying for. Psychometric testing could help to gauge the future performance of candidate's and also improve employee retention by making successful hiring decisions.

It’s important to remember that the function of a diagrammatic reasoning test will vary depending on the stage of recruitment it is being used in. When given in early stages of recruitment the test is used as a screening tool, which could mean that if you fail the test this may result in an early screening out of the selection process. When the diagrammatic reasoning test is given during the later stages of a recruitment process then this test will usually be used in combination with other aptitude tests and exercises. When this is the case, one single test category will not be the sole decider of the selection process due to the fact that more tests are of influence on your total scoring during the assessment.

The most common way for employers to use aptitude tests such as diagrammatic reasoning, is online. Traditionally, aptitude tests have taken the form of pen and paper but due to benefits such as saving valuable time and money, online testing is used more and more frequently. Undertaking aptitude tests is usually the follow-up action after an employer has accepted your CV or initial job application form. 

If you pass the online test in some cases you are invited to an assessment centre, which is usually done by larger employers. The term assessment centre is used due to the fact that employers conduct these extended assessment in a single centre, either an office of the employers themselves or at a third party venue. The assessment centre is often (but not always) a day that constitutes the final stage of the application process. At the assessment centre they will ask you to sit a repeat test at the assessment centre to verify your earlier test scores, therefore don’t get your friends or family to help you out during the online test! 

Preparing for an assessment centre or online aptitude test can be stressful due to the fact that you don’t know what to expect. The best way to familiarize yourself is with practice aptitude tests that mimic the tests used by employers and recruiters. has prepared thousands of candidates for their assessments and aptitude tests by offering realistic test simulations with fully worked solutions. 

By practicing diagrammatic reasoning tests you can improve your performance during the real test by familiarizing yourself with the format and time-pressure.

  • Diagrammatic reasoning tests are multiple-choice (only one option is correct in each case).

  • Diagrammatic reasoning tests are administered under exam conditions and strictly timed. The given time per test differs per test publisher; some tests give relatively generous time limits, while others are shorter.

  • Test takers are usually permitted to use a rough sheet of paper.
