What Are Psychometric Tests?

Psychometric tests and questionnaires have been growing in popularity, not only amongst those curious to know their own personality and work behaviour better, but also in businesses looking to hire, support and promote talent. However, the term is often used loosely, so understanding precisely what a psychometric test is can be difficult. As specialists in the field of psychometric products and consultancy, we here at eras can help you understand what these tests are and what to expect when you undertake one.

What Actually Are Psychometric Tests?

A psychometric test or questionnaire assesses one or more aspects of human behaviour; such as ability or personality, under standard conditions. The scores are expressed either as a number or in category form, which might be as a grade A to E or on a colour-coded system such as red, amber, or green. Standardising the test and making the test results objective removes potential bias and gives a more accurate reflection of a person's behaviours and assumptions.

While the term 'psychometric test' can be used to cover a multitude of areas, it is perhaps a better reflection of ability and aptitude tests. The phrase 'psychometric assessment' is a more inclusive term and more appropriate for profilers, instruments and questionnaires used to assess a person's personality traits.

How Do Psychometric Assessments Work?

The standardised process means that all job applicants undertaking the assessment receive the same instructions and questions. This ensures that the assessment is fair and consistent for all. Sometimes a time limit will be included, though this is more often specifically in the cases of ability or aptitude tests.

With personality questionnaires and profilers, the timing isn't as important. What matters is completing all of the questions, as this will give a more accurate reflection of you or the intended candidate. The term 'test' implies that there is a right answer required to pass when in reality, where personal preference is concerned, there are no absolute 'right' answers.

What Do Psychometric Tests Measure?

One of the reasons that psychometric tests are so popular is because they can, in theory, measure almost any aspect of human behaviour and assign a score to them. This has proven to be particularly popular amongst employers seeking to gain a greater knowledge of potential candidates. You can measure an array of factors which are often separated into personality questionnaires or aptitude and skills tests. Below you'll find some examples of the different elements that can build up a psychometric assessment.

The depth that psychometric assessments go into can be daunting, but it is an excellent way to understand ourselves and often appreciate how others view us. Gaining this critical insight can help you understand yourself better and prepare for career progression. Many businesses opt to use psychometric tests to ensure that they are supporting their teams in the right way and selecting the perfect candidate for the role.

What Makes A Good Psychometric Assessment?

While there are a lot of complex elements to a psychometric assessment, a good psychometric instrument will have two important properties: reliability and validity.

Reliability means that the questionnaire or test is measuring behaviour in a consistent and accurate way to minimise the number of errors. This usually means that, if the same group of people complete the assessment a second time, the results are similar or that, if people complete the questions in a different order, it would not alter the results.

Validity is the most important factor. Valid psychometric tests mean using the test in a way that is appropriate, relevant and useful. For example, if you are using psychometric assessments to test candidate suitability, the role itself should have been analysed to ensure that a clear outline for success has been identified.

How Do You Prepare For A Psychometric Test?

This is where using the term 'test' can cause issues. As stated earlier, there are no 'correct' answers to a personality assessment. The results are unique to each individual, so there isn't any revising you can do ahead of time. Candidates are encouraged to go with their instincts and what is right for them, instead of searching for the 'ideal' answer.

Even for ability tests, the good news is that, in the majority of cases, there isn't a lot of preparation involved. What concerns many is that the test is almost always timed. The ticking clock can make the process more intimidating, but it also produces more accurate results.

Many practice tests will feature this timed element, giving you the chance to prepare for answering questions under pressure. However, the best way to approach a psychometric test is to simply start the test itself. All of the psychometric assessments supplied by eras start with a few practice questions at the beginning before the timer starts. This gives you an idea of what to expect without invalidating the results.
