You've seen the CV, the references are good, the interview (phone, online, or in person) was promising. But you're still missing one piece to make your decision: how they reason, how they process information under pressure, and whether their personality profile fits the teamPsychometric tests exist precisely to answer that, but most recruiters apply them incorrectly—or don't even know which one to use for each position.
At Voicit, we speak every week with recruitment consultancies that are using psychometric tests because "they've always been done," without a clear understanding of what they're actually measuring or how to interpret the results. This guide will give you what we give them: a practical overview for recruiters (not psychologists) about the 6 main types of psychometric tests for personnel selectionreal-life examples, when to apply each one, and how to interpret them without messing up.
What are psychometric tests? These are standardized and scored assessments that measure a candidate's cognitive abilities (reasoning, memory, attention), specific aptitudes (numerical, verbal, spatial), and personality traits, with the aim of predicting their future performance in a specific role. They are used to complement the interview, never as a replacement.

What are psychometric tests and what are they really for?
A psychometric test is a psychological measurement tool standardized (all candidates go through exactly the same thing, under the same conditions) and scaled (The results are compared against a reference population.) These two features are what distinguish a serious psychometric test from a homemade questionnaire.
In personnel selection, they fulfill three functions that the interview cannot adequately cover:
- Objective prediction of performance. Decades of meta-analysis (Schmidt & Hunter, among others) show that general cognitive ability tests are one of the most valid predictors of job performance, above the unstructured interview.
- Reduction of interviewer bias. A person who makes a good impression in an interview may not perform well; an introverted person may excel in the role. The test shows no correlation between likeability and aptitude.
- Scalable screening. When you have 80 candidates for 3 positions, you can't interview them all. An online tool ranks the list by aptitude before investing human time.
Which no They're not Instagram personality tests, they don't diagnose disorders, they're not infallible, and they should never be the sole decision-making criterion. If someone sells them to you as "the magic wand of selection," be wary.
The 6 main types of psychometric tests for selection
There are dozens of tests on the market, but 95% of personnel selection uses tests that fall into one of these six categories. For each one you will see what it measures, when to apply it, and a real-world example of question or item.
| Guy | What does it measure? | Typical duration | Best for |
| Verbal aptitude | Language comprehension and use | 15-25 min | Sales, communication, customer service |
| Numerical aptitude | Reasoning with data and calculations | 20-30 min | Finance, controllers, analysts |
| Abstract reasoning | Logic and fluid intelligence | 15-25 min | Any skilled position, IT, consulting |
| Spatial aptitude | 3D visualization and orientation | 15-20 min | Engineering, design, architecture, production |
| Personality | Stable traits (Big Five and derivatives) | 25-45 min | Cultural fit, leadership, business profiles |
| Attention and concentration | Speed, accuracy, mental stamina | 5-15 min | Production, quality control, operations |
1. Verbal aptitude
Typical questions include synonyms and antonyms, verbal analogies (A is to B as C is to ?), reading comprehension with inferential questions, and logical paragraph ordering. It is an essential test for positions where the candidate will be writing business emails, proposals, or working directly with clients.
2. Numerical aptitude
It doesn't measure advanced math: it measures reasoning with numbers under pressureNumerical series, problems with table data, unit conversion, and rapid calculations are all present. This is critical for finance professionals, controllers, and even many sales positions with KPI-based incentives.
3. Abstract reasoning (fluid intelligence)
The most well-known test is the matrix test (Raven's or BFD-PM style): series of figures with a hidden pattern are shown, and the candidate must choose the one that completes the series. It's useful in virtually any position requiring analytical thinking, especially in consulting, IT, and roles where the candidate will be learning a new business from scratch.
4. Spatial aptitude
Essential in engineering, architecture, industrial design, mechanics, and production. Typical tasks include: identifying the flat shape formed when a cube is unfolded, mentally rotating a part, or recognizing the side view of an object from its front view.
5. Personality tests
Caution is advised here: personality tests They are neither passable nor failableThey are useful for assessing role and team fit. A highly extroverted profile will be a better fit for sales; someone with high openness and low agreeableness might be an excellent researcher or auditor but a poor team manager. Avoid MBTI-type tests for selection: they are scientifically discredited for career prediction.
6. Attention and concentration tests
Crucial for operational roles where a moment of distraction can have consequences: quality control, professional driving, security, machinery operation, and intensive customer service. These are short (5-15 minutes) but demanding tests: the candidate must identify and mark a specific pattern among hundreds of stimuli within a limited time.
Matrix: which test to apply depending on the position
It doesn't make sense to administer a full battery of tests to all candidates. This matrix summarizes which tests are appropriate. essential, recommended u optional depending on the type of role. Adapt it to your specific sector.
| Position | Verbal | Numeric | Abstract | Space | Personality | Attention |
| Commercial / Sales | Yeah | Yeah | Option | — | Yeah | Option |
| Finance / Controller | Option | Yeah | Yeah | — | Option | Yeah |
| IT / Development | Option | Yeah | Yeah | Option | Option | Option |
| Customer service | Yeah | Option | Option | — | Yeah | Yeah |
| Engineering / Production | Option | Yeah | Yeah | Yeah | Option | Yeah |
| Operations / Warehouse | — | Option | Option | Option | Option | Yeah |
| Middle management | Yeah | Yeah | Yeah | — | Yeah | Option |
| Management / C-level | Yeah | Yeah | Yeah | — | Yeah | — |
Yeah = essential Option = recommended depending on specialization — = low relevance.
How to interpret results without being a psychologist
This is where most recruiters go wrong. A psychometric test score It does not interpret itselfbut always compared against a reference standard. These are the basic concepts you need to master:
Percentiles (Pc): the metric you'll read the most
The percentile indicates what percentage of the reference population scored lower than or equal to the candidate's score. Pc 75 means the candidate outperformed 75% of the population; Pc 25 means they outperformed only 25%.
- PC 1-25: Low performance. Only acceptable if the test is marginal for the position.
- PC 26-49: Performance below average. Acceptable in secondary skills.
- PC 50-74: Average performance. Suitable for most positions.
- PC 75-89: High performance. A good sign in key role skills.
- PC 90-99: Very high performance. Excellent, but beware of overqualification if the position doesn't require it.
| PC 1-25 | Low · only acceptable if the test is marginal for the position |
| PC 26-49 | Below average · acceptable in secondary skills |
| PC 50-74 | Medium · suitable for most positions |
| PC 75-89 | High · good sign in key role skills |
| PC 90-99 | Very high · excellent, but beware of overqualification |
Enneagram types and deciles: variations you may encounter
Some scales use enneagram types (scale 1-9) or deciles (scale 1-10) instead of percentiles. The interpretation is equivalent: 5 is the center, 1-3 is low, 8-10 is high.
The criteria matter more than the raw score
Combination with the interview: the 60/40 rule
The most solid practice in reputable consulting firms: the evidence provides ~60% objective evidence Regarding cognitive aptitude and stable traits; the interview provides ~40% on fit, motivation, and situational experienceDecisions that ignore either side are half-baked decisions.
7 mistakes that invalidate your psychometric test results
After speaking with hundreds of recruitment consultancies, these are the most common mistakes that destroy the reliability of psychometric tests:
- Apply the same battery to all stations. A spatial aptitude test for a sales position is just noise. The matrix above is there for a reason.
- Not verifying identity in online tests. If the candidate takes the test from home without proctoring (a camera verifying their identity), you have 0% certainty about who actually answered it. This is acceptable for mass screening; not for finalists.
- Interpreting scores without a scale. "She scored 78 points" tells us nothing. Compared to how many? Compared to what population? Without a benchmark, there's no possible interpretation.
- Using unvalidated tests. Any reputable test has a technical manual with reliability coefficients (Cronbach's alpha > 0.70) and validity. If the provider doesn't show it to you, it's not reputable.
- Relying on the MBTI or "16 personalities" tests. They lack predictive validity for selection. Use instruments based on the Big Five (NEO-PI, 16PF, BFQ).
- Apply tests without informed consent. It violates GDPR. The candidate must know what tests they will take, why, who will see them, and how long the data will be kept.
- Making hiring decisions based on a single test. The validity of any single predictor is limited. Composite validity (several predictors combined) is what truly improves the decision.
How to combine psychometric tests with the interview (step-by-step process)
The classic mistake: you administer the tests, the interview arrives, and nobody cross-references the data. The result: the interview is conducted "blindly," and all the objective information you already had is lost. This is the workflow we recommend to the consulting firms we work with:
Step 1 — Initial screening (first week)
- Online cognitive aptitude tests (verbal + numerical + abstract): 45 minutes maximum.
- Filter the top 30% by key job skills before investing human time.
Step 2 — Personality and role fit (second week)
- Apply personality test (Big Five) to candidates who pass screening.
- Generate individual report focusing on the 2-3 most critical traits for the role.
Step 3 — Informed interview (third week)
- The interviewer enters the interview with the psychometric report in front of him.
- Design questions for verify and delve deeper What the test revealed: if the test indicates low emotional stability, prepare situational exercises on pressure management; if it indicates high openness, investigate examples of self-directed learning.
- This is where it goes VoicitRecord the interview with the candidate's consent and, in less than 5 minutes after it ends, receive a structured report with the candidate's verbatim answers to each competency block. This allows you to compare what they said with what the test revealed without having to take notes live.
Step 4 — Evidence-informed decision (fourth week)
- Committee meeting with three documents: psychometric report + interview report + competency scorecard.
- Decision by triangulation of sources, not by the intuition of a single interviewer.
Cross-reference psychometric results with interview in minutes
Voicit records the interview, transcribes it into Spanish, and delivers a competency-based report. Compare that report with the psychometric test and make your decision based on evidence, not intuition.

Frequently asked questions about psychometric tests
Are psychometric tests mandatory in a personnel selection process?
No, they are not legally required in Spain for private sector positions. They are required for competitive examinations and processes for public sector jobs (police, firefighters, certain civil service positions). In the private sector, they are a recommendation of best practices, not a legal obligation.
Can psychometric tests be "studyed"?
Practice slightly improves performance due to familiarity with the format (training effect), but it doesn't transform a candidate from PC30 to PC90. The underlying cognitive ability remains stable. What does happen is that candidates who practice perform somewhat better on the first test, but the difference diminishes in subsequent tests.
How much does it cost to administer psychometric tests?
Online cognitive aptitude tests range from €5 to €25 per candidate, depending on the provider and the number of tests purchased. Complete batteries with personality assessments can cost €40-€80. For serious recruitment processes, the ROI is clear: the cost of a bad hire far outweighs the cost of the tests.
How long are the results of a psychometric test valid?
Cognitive aptitude tests are reasonably stable throughout adulthood, so results from 2-3 years ago can still be considered indicative. Personality tests show more variability; it is recommended to update them every 3-5 years. For a specific selection process, it is essential to administer tests within the process itself, rather than reusing the candidate's old results.
Can I administer psychometric tests to candidates without being a psychologist?
The administrative application (sending the link, monitoring) yes. But the clinical interpretation The interpretation of the results is reserved for licensed psychologists according to the Code of Ethics of the General Council of Psychology in Spain. The usual practice is to contract the service from a provider that includes a report signed by a licensed psychologist.
Which psychometric testing providers do reputable consulting firms use?
The most established providers in Spain are: TEA Ediciones (BFQ, 16PF, NEO-PI-R, d2-R, BAT-7), Hogan Assessments, Pearson TalentLens (Watson-Glaser, Wonderlic), SHL/CEB, and Cubiks. For newer digital environments: Bryq, Aon Cut-e, and Mercer Mettl. Always request a technical manual before signing up.
Do psychometric tests work the same online as in person?
For initial screening, yes, with two precautions: (1) verify identity with proctoring if the decision depends on that result, (2) time-limited tests are very dependent on the internet connection, so make sure the candidate takes it under conditions equivalent to those of the standardized population.
Actionable summary
If you only take away three ideas from this guide:
- Apply only the tests relevant to the position. Use the matrix above as a starting point and adapt it to your sector. An unnecessary battery of tests tires the candidate and dilutes the data.
- Do not interpret scores without a scale. Always ask for the contextualized report and, if you make critical decisions, demand the signature of a licensed psychologist.
- Combine the psychometric test with the interview. The 60/40 process (test + interview) doubles the quality of selection decisions compared to using only one of the two channels. If the bottleneck is the time required to process interviews, tools like Voicit They give you the structured report in less than 5 minutes per interview.
