A candidate can achieve a high score on a particular scale without being the right person for the role. That is why the question “how do you interpret test results?” is crucial for anyone who wants to use occupational psychological tests as a genuine decision-support tool – rather than as a label, a shortcut or a definitive answer.
Accurate interpretation begins with the work that needs to be done. A test result only gains value when it is compared with clearly defined requirements for the role, supplemented by structured information and assessed by someone who understands both the measurement method and the needs of the organisation. Used in this way, testing can contribute to more accurate, fair and commercially sound decisions in recruitment, management selection and development.
How do you interpret test results without overinterpreting them?
The most common mistake is to read a result as a rating of an individual’s overall capability. An occupational psychological test instead describes likely behaviours, motivations or capabilities within the specific areas that the test actually measures. A person with a low score on a particular scale is not less competent. The result may, however, indicate that the individual could benefit from a different working environment, clearer support or a different way of working in order to perform well.
Interpretation must therefore always be role-specific. High social energy, for example, may be relevant in a sales role involving frequent contact with new customers, but less important in a specialist role requiring long periods of concentrated analytical work. Similarly, a strong result in logical reasoning may be particularly relevant when the role requires the employee to process complex information quickly, while other competencies may carry greater weight in an operational management role.
A test result is therefore one part of the evidence, not the decision itself. This principle protects both the quality of the selection process and the candidate experience.
Start with a clear role profile
Accurate interpretation is impossible unless the organisation has first defined what success in the role actually means. The role profile should describe the tasks, behaviours and abilities that genuinely affect performance. It should be based on job analysis, discussions with the manager and successful employees in similar positions, as well as an understanding of the environment in which the person will work.
For a site manager, for example, the requirements might include the ability to prioritise under time pressure, create structure, take responsibility for the working environment and lead different professional groups. For an HR strategist, analytical ability, integrity, collaboration and the ability to move between detail and the bigger picture may be more important. Both roles require capable employees, but the test results should be compared against different criteria.
Once the role profile is clear, you can also determine which results are critical, which are desirable and which should primarily be explored further during the interview. This reduces the risk of placing too much emphasis on a single result that differs from expectations.
Compare against the right reference group and target profile
Norm groups show how an individual’s results compare with those of a relevant reference group. They are useful, but on their own they do not answer the question of whether the person is suitable for the job. An above-average result may be a strength in some roles while having little practical significance in others.
A target profile or comparison profile, on the other hand, links the result to the requirements of the role. The question then becomes not “is the score high?” but “how well does this pattern correspond with what is required to succeed here?” This is a more relevant and fairer starting point.
It is also important to consider how close a candidate’s profile is to a threshold. Small differences in results should rarely be interpreted as major differences in job performance. Psychometric measurements always contain a degree of measurement uncertainty. Results close to a threshold should therefore be followed up with specific, structured interview questions rather than being used as an automatic yes or no.
Look at the pattern, not individual scales
Personality results are most useful when analysed as a coherent pattern. A high level of drive, for example, can be very positive, but needs to be understood alongside results relating to patience, structure, risk-taking and collaboration. The same characteristic can contribute to strong performance in one environment and create friction in another.
It is also important to remember that strengths can have a downside depending on the context. A person who readily makes quick decisions can create momentum in a customer-facing team, but may need a counterbalance in a role where quality assurance and documentation are central. A highly meticulous person can provide stability and precision, but may experience pressure in roles where priorities are constantly changing.
This is why feedback on test results should focus on workplace behaviours rather than fixed personal characteristics. Ask: When is this tendency most valuable? When might it become a challenge? What conditions, working methods or support increase the likelihood of strong performance?
Check the quality of the test before using the results
A well-managed testing process cannot compensate for a test with a weak scientific foundation. Before test results are allowed to influence recruitment or development decisions, you should ensure that the method has documented validity and reliability.
Reliability concerns the stability and precision of the measurement. Validity concerns whether the test actually measures what it is intended to measure and whether the results are relevant to factors such as job performance. For selection tools, it is particularly important that there is evidence supporting the relationship between results and work-related criteria.
Independent quality assessment provides additional assurance. DNV’s review and certification in accordance with EFPA’s test review model is one example of external quality assurance that helps users evaluate a test’s documentation, usability and scientific foundation. This is particularly valuable when the test is used as a basis for decisions that affect both the organisation and the individual.
Also ensure that candidates are given equivalent conditions, clear instructions and sufficient information about how the results will be used. Ability tests need to be conducted under conditions that provide a fair representation of the individual’s capabilities. Language, time pressure, technical difficulties and unfamiliarity with testing can otherwise affect the outcome.
Link test results to a structured interview
The test should improve the interview. It should not replace it. When a result indicates a potential strength or risk, the interviewer can formulate questions that seek specific examples from the candidate’s previous work.
If the test results indicate that the candidate prefers a fast pace and quick decision-making, the interviewer might ask: “Tell me about a time when you had to make a decision with limited information. How did you ensure the quality of your decision?” If the results suggest a strong need for structure, the follow-up question might explore how the candidate handles sudden changes, conflicting demands or unclear mandates.
A structured interview provides two advantages. It allows you to test whether the hypotheses generated by the assessment correspond with actual experience, while ensuring that all candidates are evaluated against the same relevant criteria. This reduces the influence of gut feeling, similarity bias and impressions created by individual well-formulated responses.
Reference checks can be used in the same way. Start with the role profile and ask the referee to describe observable workplace situations. Avoid using the test result as a hidden framework for confirming an initial impression. The purpose is to gather complementary facts, not to search for evidence supporting a decision that has already been made.
Use the results differently for selection and development
In recruitment, the focus is on the likelihood of performance in a specific role. The assessment therefore needs to be consistent across candidates and based on predetermined criteria. Test results should be considered alongside relevant experience, competency-based interviews, work samples and, where appropriate, ability tests.
In development, the conversation is often broader. Here, the results can help a manager and employee understand working style, communication, recovery, leadership or c
