You can learn a lot about a candidate in an interview, but some abilities are difficult to assess through conversation alone. How well can they interpret unfamiliar information? How do they judge competing courses of action?
A psychometric test can provide evidence to help answer those questions. Here, we explain what these tests measure, how they can support recruitment, and what Kenyan employers should consider when using them.
What Is Psychometric Testing?
Psychometric testing is a structured way of assessing a person’s abilities, personality traits, or behavioural tendencies. Candidates complete a set of questions or tasks, and their responses are scored and interpreted using established methods.
In recruitment, employers use the results to understand how a candidate’s abilities and working preferences relate to a role’s requirements. Common assessment types include:
| Assessment type | What it assesses | Recruitment use |
| Ability and aptitude tests | Numerical, verbal, logical, or abstract reasoning. | Assessing abilities relevant to tasks such as interpreting financial information or solving unfamiliar problems. |
| Personality questionnaires | Self-reported preferences and tendencies in how someone works and interacts with others. | Identifying areas to explore during interviews, such as teamwork, attention to detail, or adapting to change. |
| Situational judgement tests | How candidates judge possible responses to workplace scenarios. | Exploring judgement in situations relevant to the role, such as handling a customer complaint or competing priorities. |
Each assessment provides different information. Choose the type according to what you need to understand about the candidate and why it matters to the role.
How Can Psychometric Testing Improve Hiring Decisions?
Psychometric testing can help identify potential mismatches between a candidate and the role before making an offer. It allows you to:
Look Beyond the CV and Interview
CVs record qualifications, employment history, and claimed achievements. Interviews allow employers to explore that experience, but candidates can rehearse answers, and interview confidence does not always translate into ability.
A suitable assessment can examine certain capabilities more directly. For example, a reasoning test can show how a candidate interprets unfamiliar information, adding evidence beyond their description of their analytical skills.

Compare Candidates More Consistently
Personal impressions can influence interviews. A confident or familiar candidate may receive the benefit of the doubt, while a quieter candidate may be underestimated.
Giving applicants the same relevant psychometric assessment under comparable conditions provides a common basis for comparison. The hiring team can discuss how candidates performed on specific measures alongside the evidence gathered during interviews.
Test What the Job Actually Requires
Psychometric assessments give employers evidence of abilities candidates will need for the position. For example:
- For a financial analyst, a numerical-reasoning test can show how accurately candidates interpret figures and draw conclusions from data.
- When recruiting a supervisor, a situational judgement test can explore how candidates evaluate possible responses to complaints, competing priorities, or employee concerns.
These results give the hiring team specific evidence to consider when deciding who is best equipped to meet the role’s demands.
Ask Better Interview Questions
Test results can highlight areas to explore during an interview. If a questionnaire suggests that a candidate prefers predictable routines, for example, you could ask: “Tell us about a time your priorities changed unexpectedly. How did you decide what to do?”
Use the answer to explore how the candidate has handled similar situations at work. This gives you more context for interpreting the result and deciding how much weight it should carry in the hiring decision.
How to Use Psychometric Tests in Recruitment
A clear process helps your hiring team choose a suitable assessment, prepare candidates, and use the results consistently.
- Define what you need to assess. Review the job description with the hiring manager and identify the abilities or working preferences you need to understand. Decide which questions testing can help answer and which require an interview, work sample, or reference check.
- Choose a suitable assessment and provider. Ask for evidence that the test produces sufficiently consistent results and supports the conclusions you intend to draw. Check who candidates’ scores will be compared with, whether that group is relevant, and what training is needed to administer the assessment and interpret its reports.
- Agree how testing fits into selection. Decide when candidates will take the assessment, who will review the results, and how those results will contribute to shortlisting or the final decision. Set these arrangements before seeing individual scores.
- Prepare candidates and administer the test. Explain the assessment’s purpose, format, expected duration, and technical requirements. Tell candidates how their information will be used and give them a way to request adjustments. Follow the provider’s administration guidance and record any interruptions or difficulties that could affect interpretation.
- Review the results alongside other evidence. Have someone with the appropriate assessment training explain the findings and their limitations to the hiring team. Follow up on relevant questions during interviews, investigate conflicting evidence, and document the reasons for the final hiring decision.
Employers also need to recognise common mistakes in interpreting and applying the results.
Where Can Psychometric Testing Go Wrong?
A precise-looking score can seem more conclusive than it is. A candidate who scores 72 rather than 68 has not necessarily demonstrated greater suitability for the job. Small differences may carry little practical meaning, so employers need to understand the provider’s guidance before using scores to rank applicants.
Personality results can also be misread. A preference for independent work does not establish that someone is a poor team player. Explore how that preference appears in practice and whether it would affect the work, rather than treating a trait as a reason to reject the candidate.
Be careful with “culture fit” too. Looking for people who resemble the existing team in personality, background, or outlook can exclude capable applicants. Focus on behaviours relevant to the organisation’s work and values, such as sharing information or taking responsibility for mistakes.
Assessment conditions can also affect results. Language, accessibility, and technology requirements may prevent candidates from demonstrating their abilities fully. A low score may therefore reflect a barrier in taking the assessment rather than difficulty with the work itself.
Legal Considerations for Kenyan Employers
Employers must ensure that their psychometric testing complies with Kenya’s employment and data protection laws.
Fair Selection
Section 5 of the Employment Act requires employers to promote equal opportunity and prohibits direct and indirect discrimination against prospective employees. This covers recruitment procedures and selection criteria.
Document why the assessment and any minimum score are relevant to the role. If particular groups consistently receive lower scores, investigate whether the test, testing conditions, or selection criteria create an unjustified barrier.
Candidate Data
Assessment responses and reports linked to an identifiable candidate are personal data. Under Kenya’s Data Protection Act, employers need to identify an appropriate lawful basis for collecting and using that information.
Tell candidates what information is being collected, why it is needed, how it will be used, and who may receive it. Restrict access to people who need the reports, retain information only as long as necessary, and check how an external provider stores, protects, and deletes it.
Our guide to HR data protection in Kenya explains how to manage personal information throughout the employment lifecycle.
Automated Decisions
Section 35 of the Data Protection Act gives individuals a right not to be subject to solely automated decisions that produce legal effects or significantly affect them. The Act provides exceptions, with notification and reconsideration safeguards.
Build meaningful human review into selection. The reviewer should understand the assessment’s limitations, consider other relevant evidence, and have the authority to change the recommended outcome.
How Can Employers Tell Whether Testing Is Helping?
Compare hiring outcomes for similar roles before and after introducing the assessment, and examine whether scores relate to performance after appointment.
Over time, track:
- Probation and performance: Do results in the capabilities tested correspond with probation outcomes and role-specific performance?
- Time to productivity: Are successful candidates reaching the expected standard sooner?
- Early turnover: Why are new hires leaving, and did the selection process miss anything relevant?
- Candidate participation: Are candidates completing the assessment, or are its length, accessibility, or relevance causing withdrawals?
- Selection patterns: Are particular groups being screened out disproportionately at the testing stage?
Avoid drawing conclusions from a small number of hires. If high-scoring candidates repeatedly struggle, or candidates with lower scores later perform well, review the assessment, the required score, and the weight given to it.
Performance also depends on what happens after recruitment. Poor onboarding, unclear expectations, or weak management can affect productivity and retention, so these outcomes should prompt investigation rather than an immediate verdict on the test.

Use Psychometric Testing to Inform Hiring Decisions
Psychometric testing is most useful when it answers a clear question about a candidate’s suitability for the role. Choose each assessment with that purpose in mind, weigh the findings alongside other recruitment evidence, and review whether testing improves your hiring decisions over time.

Frequently Asked Questions
Are Psychometric Tests Accurate?
No assessment can predict job performance perfectly. A well-designed test can provide useful evidence about specific abilities or traits, but its value depends on its quality, administration, and relevance to the role.
Can a Candidate Fail a Psychometric Test?
It depends on the assessment. A candidate may fall below the required score on an ability test, but personality questionnaires are not usually passed or failed. The employer should decide whether the results meet the requirements of the specific role.
Is a Personality Test the Same as a Psychometric Test?
A personality questionnaire is one type of psychometric assessment. The broader term also includes ability, aptitude, and situational judgement tests.
Should Test Results Determine Who Gets Hired?
They should inform the decision, alongside interviews, work samples, experience, and references. A score alone should not decide who receives an offer.
Can Psychometric Tests Be Used for Existing Employees?
Yes. Suitable assessments can support employee development, succession planning, and internal selection.
