Should you be using psychometric testing?

psychometric testing

Psychometric testing has become a multi-million pound business, but it isnt right for every small firm. We looked at some of the pros and cons of the recruitment tool.

Around 70 per of large companies in the UK use psychometric tests as part of their recruitment process, with many micro firms starting to consider them too. There are two main types of test aptitude or ability tests and personality tests. Employers use them to help build a full and complete picture of potential employees.

However, psychometric tests do not provide a definitive answer to all recruitment decisions. There are both positive and negative sides to using them, and these need to be weighed when assessing whether they are right for your needs. In this article, we are going to provide a brief overview of the pros and cons to help you decide whether you should consider using them.


At their best, psychometric tests can give you a relatively accurate and insightful picture of a candidate’s suitability for a role. For example, if you’re looking for a quality salesperson, then someone who is an extrovert with high verbal reasoning skills and high achievement motivation is a better bet than the introvert who specialises in abstract thinking.

Well-validated tests generally return reliable results and can help you avoid the situation in which a person is an interview star, but unable to back it up with performance in the job role. And given how costly recruitment mistakes are, tests are a good insurance against them. They can weed out the bad choices and reveal the exceptional performers, as well as helping you assess how good a fit? someone is to a team or a role based on personality and ability.

Additionally, using psychometric testing helps to give companies a benchmark to work to in terms of objectively measured abilities that are displayed by candidates. Tests are standardised so every candidate gets the same questions and has the same opportunity in the interview process.

They can also identify areas of concern and provide the recruiter with an opportunity to explore these with a candidate before employing them. This can be done by arranging further interviews where they take a more in-depth look at certain areas, or by focusing on specific areas when doing reference checks, based on the test results and findings. Testing can also provide the recruiter with upfront information on the candidate’s strengths and limitations prior to recruiting, which can be used to help identify the best way manage the new recruit once he or she joins the company.

Finally, they can give applicants with weaker interview skills or candidates who are shy a chance to prove they can be valuable to the company by showing their real value.


Psychometric tests are developed and validated using sample populations that have no reason to be dishonest and hence respond from this standpoint. However, job applicants are motivated to tell you what you want to hear, which can skew the responses so they are not necessarily accurate. Standard tests are widely used and therefore a candidate who really does their homework can study these tests and work out the most appropriate answers for the type of person the company is looking to recruit. Some candidates will even pay for coaching in this.

On top of this, test anxiety, nervousness, time pressures and unfamiliarity can sometimes create a false negative, so that a person’s results do not reflect what they are capable of and what their true potential would be in the role.
