Aptitude Test Design
Aptitude tests give one a sense of how good of a fit you are to perform certain tasks – or how likely you are to learn a skill. You will find plenty of aptitude test practice and aptitude test tips on this website.
Aptitude test practice
To help you improve their cognitive abilities and prepare for aptitude tests in a variety of settings. Whether you are a student preparing for college entrance exams or a job seeker looking to improve your chances of success in a competitive job market. How to interpret test results and how to use them to improve performance in future assessments.
Our Bespoke Psychometric Design Principles
For training consultancies, Rob Williams Assessment Ltd has built coaching and employability profiling tools.
With recruitment agencies we’ve designed culture and role fit personality-based assessments to improve the efficiency of matching clients to the best-fitting jobs.
Our psychometric test design solutions
- Our consultancy work focuses on aptitude test practice and bespoke psychometric test design.
- We believe in the benefits of practice and ensuring fairness in testing. We, therefore, offer some practice aptitude tests and some practice psychometric tests. The intention is to promote as ‘level a playing-field’ as possible.
Our SJT designs
As psychometric tests have become more commonplace, the bigger users have commissioned their own bespoke situational judgement tests.
Rob Williams Assessment has worked on several such projects for High Street banks and for the European Union. Another recent innovation of test developers has been online adaptive tests. With these tests, if you are doing well, you will find that the questions get progressively harder.
The innovative design of shorter and more efficient tests was driven by an increasingly aware of the immediacy of the Internet and our increasing use of emails and social media, in short, sharp bursts.
This discourages test takers from spending 30-40 minutes online doing the same questionnaire. It’s better for everyone to keep test takers engaged when being tested – not bored!
Knowledge-based situational judgement test design
Some or all of the scenarios presented in an SJT can test specific job knowledge. For example, a retail marketing SJT may ask questions about the 3Ps (price, position, promotion) of product marketing. Alternatively, both an SJT measuring generic decision-making skills may be used alongside a knowledge-based test.
Our video-based situational judgment test designs
Simulated situational judgement tests are increasingly common as recruitment sifts. Adding 2D or 3D workplace scenario graphics brings the situational judgment test scenarios to life. This can only promote the company brand and make employers using simulated situational judgment tests more desirable employers.
psychometric test design
UK and US psychometric test publishers have produced both video-based and animated SJT scenarios. Animated SJTs are easier – and therefore cheaper – for global companies to develop.
Our consultancy work focuses on aptitude test practice and bespoke psychometric test design. We believe in the benefits of practice and ensuring fairness in testing. We, therefore, offer some practice aptitude tests and some practice psychometric tests. The intention is to promote as ‘level a playing-field’ as possible.
Values based recruitment
Example values-based recruitment Question – Describe an example of when you have made a decision which had a positive effect on a customer?
Probes: What actions did you take? Who was involved? What was the outcome of your actions?
Positive behavioural indicators
- Uses their initiative.
- Takes personal responsibility.
- Describes the example’s context, their actions and the outcome(s).
Negative behavioural indicators
- Applies limited effort.
- Only describes own actions.
- Omits the outcome.
- Doesn’t describe their individual contribution.
We always follow BPS Standards in Psychometric Test Design
To be psychometrically sound a test must be:
- Objective – the results obtained are not influenced by the administrator’s personal characteristics or irrelevant factors such as the colour of a test taker’s socks.
- Standardised – the test is administered and scored according to standard procedures and people’s scores are compared to known standards.
- Reliable – the test measures in a consistent way. The potential error is small and is quantifiable.
- Valid. Our psychometric test design measures the characteristic(s) that it set(s) out to measure. So, if we design a sift psychometric test to select a job applicant should predict job performance. Whereas, if we design a psychometric test of verbal ability then it will predict verbal reasoning abilities.
- Discriminating. Any of our bespoke psychometric tests designs should show clear differences between individuals on the behaviour being tested. But should not be discriminatory. In other words our psychometric test design does not unfairly discriminate against a minority group.

Test Quality Standards
In all cases ensure that:
Never just reuse tests or exercises without reviewing their effectiveness in the past.
- Firstly, the choice and construction of each assessment method flows from the requirements of the job;
- Secondly, the Job description and Person Specification have been reviewed and are up-to-date
- Thirdly, tasks in assessment exercises compare with tasks found in the job;
- Fourthly, tests and exercises assess requirements for the job, at the right level to do the job
- When using a newly devised test or exercise, wherever possible pilot it with a group of existing employees in the area of work.
- Always offer feedback on test and exercise results.
- Never just reuse tests or exercises without reviewing their effectiveness in the past.
Recent situational judgement test trends
Situational judgement tests (SJTs) have also become prevalent in graduate recruitment. These tests present scenarios to applicants and ask them to select the best and the worst thing to do next. SJT’s are very popular in the United States due to their excellent record of fairness across different ethnic groups.
Recent personality test trends
Candidates may also have to take a personality test as part of the recruitment process. There is a vast array of personality tests, which pose questions about a candidate’s behaviour and personal preferences. A typical question may ask whether you prefer attending parties or staying home with a good book. These personality tests help employers to determine whether a candidate has the right profile for the role.
How companies use aptitude tests
Aptitude tests are used by many companies as a standard part of the recruitment process. If you’re currently aplying for jobs, you’re likely to face one or more psychometric tests, measuring everything from verbal reasoning and numeracy to emotional intelligence. I would say that 90 per cent of big companies use skills and/or aptitude tests, though the kind used will depends on the role and industry you’re aplying for,’ says Rob Williams.
How you perform matters. ‘Even if you wow a potential employer with a great first or second interview, the results can make or break your chances of getting hired,’ says Rob. Research backs up the claim. Nearly 90 percent of companies said they would reject candidates if the test showed them to be deficient in basic skills, according to a survey by the American Management Association.
What are the most commonly used aptitude tests? The most commonly used aptitude tests measure numerical, verbal and logical reasoning,
Our assessment designs – graduate psychometric test design example
Graduate recruiters who want to minimise recruitment costs see online ability tests as an efficient and effective means of sifting the initial applicant pool.
A bespoke verbal reasoning test design and numerical reasoning test design offer a reliable and standardised solution. This should ensure that an optimal number of good candidates are seen by the business at the much more expensive ‘face-to-face’ stage.
Using standardised tests to improve your diversity of hires
Using standardised tests in the recruitment process helps to ensure that applicants from different countries and from different ethnic groups are treated fairly.
Aptitude test design – Employability example
All of our psychometric test practice resources are free. So, we hope you enjoy using them! In our opinion, there is plenty of the right type of aptitude test practice, aptitude test tips and test-taking strategies.
We certainly hope you get maximum value from our free psychometric test practice resources! Psychometric test practise works best when it’s specific to the test type and the level of difficulty of the psychometric test you will be taking.
Best practice in assessment design
- Our first point is that a well-designed selection procedure focuses on predicting a graduate’s competence within a particular work context.
- Secondly, that psychometric assessments only form one part of the selection procedure.
- Our third point is that personality assessments can give an indication of how well an individual applicant will fit into the existing workplace or team.
- Finally, psychometric assessments can assess which applicants are most suited to the demands of the vacant job in terms of both ability and personality factors.
Best practice uses of aptitude test data
- Firstly, it’s fundamental to the use of any psychometric test is that users are aware of a test’s effectiveness and its known limitations. This information is calculable through knowledge of a measure’s reliability and validity.
- Secondly, importance is attached to test results and decisions are made using test data.
- Thirdly, you must be sure that the tests you are using have sound credentials and have been properly developed.

Psychometric test design pillars
An IQ test compares each respondent’s IQ score with a group of previous test-takers. There needs to be a standardization phase when developing any aptitude test.
This standardization sample provides the norm group against which the individual scores of all later psychometric test respondents are compared. Otherwise, an ‘IQ score’ would be meaningless!
The second psychometric test property is…
Reliability
There are two key types of psychometric reliability. In each case, ‘psychometric test reliability’ means that if I take the same test next week, my results will be similar.
Internal Reliability, or Internal Consistency
This is the first type of psychometric test design reliability.
Whether all the test items measure the same concept. It can be assessed in two ways. The first method is known as the split-half reliabilitywhich require correlating the score based on half of the test items with the score based on the other half (e.g., scores on odd and even items).
An alternative method is item-total reliabilitywhich requires correlating each item score with the total score of the rest of the items.
Cronbach alpha then summarises all the psychometric test reliability correlations into one figure. A test should have an alpha of at least a = .80.
Our Bespoke psychometric test designs
Secondly, Test-retest Reliability relates to psychometric score consistency over time. In other words, how reliably a psychometric test measures. A time gap of at least two weeks between the two measurements is key. Since some psychological characteristics change considerably over time.
Then, the test re-test reliability is assessed by correlating the tests scores measured first time with the test scores measured the second time. Ability tests are expected to have a reliability of at least r = .75, yet personality tests might have somewhat lower reliability.
Validity
Psychometric test design validity means the test measures what it says it measures. MindX knows which personality traits are measured because we have compared our results to well-established personality tests. HireVue validates its video assessments using high performer data and job analysis results.
Aptitude Test Design Reliability – is it a reliable measure?
- Most commonly the internal consistency index coefficient alpha or its dichotomous formulation, KR-20.
- Under most conditions, these range from 0.0 to 1.0.
- 1.0 is a perfectly reliable measurement.
- Although, a reliable test may still not be a valid
Aptitude Test Design Validity – Secondly, is the test valid?
A measure of what it ‘says on the tin’? In our opinion, both the initial content validation and later criterion validation analysis are vital for any bespoke psychometric test.
Final Validity Recommendations
We recommend collecting additional recruitment data over time so that additional validation studies can be conducted. Such as assessment centre data.
There are many other types of psychometric test validation evidence, and one-off studies investigating a psychometric test’s criterion validity are common.
But what does my psychometric score mean ?
If used as a sift at an early stage of the recruitment process then there will be a specific mark that you have to pass in order to proceed further with your application.
When used as part of an assessment centre, a psychometric test is unlikely to be used a sift that excludes a % of applicants. In other words, your test score will be used to provide additional information but would not be the only reason why you succeed or fail at this particular stage.

Can you cheat or fake your psychometric test?
Our expert answer is not very easily.
- We say this mainly because modern psychometric personality tests are difficult for a candidate to cheat on as there are no right or wrong answers in these tests.
- Similarly, aptitude tests are time- limited, meaning you can objectively measure aspects of a candidate’s mental ability within the set time limit.
