Our approach to fair, evidence-based assessment

Taking part in an assessment can feel like a significant moment. We want every candidate to understand what they are being asked to complete, why the assessment is used, and how we work to make the process fair, relevant and professionally governed.

Our assessment tools are designed to support better hiring and development decisions by gathering structured evidence about how people think, make decisions, solve problems, respond to realistic work situations and approach role-relevant challenges.

They are not designed to catch people out, make clinical judgements, or reduce a person to a single score. They are one part of a broader decision-making process, alongside interviews, experience, role requirements and other relevant evidence.

What our assessments measure

Our assessments are designed around clearly defined workplace capabilities. Depending on the role and assessment being used, candidates may be asked to complete exercises that explore areas such as:

  • Judgement in realistic work situations
  • Decision-making under pressure or ambiguity
  • Commercial and strategic reasoning
  • Prioritisation and trade-off thinking
  • Self-awareness and adaptability
  • Performance orientation and accountability
  • Talent, people and stakeholder judgement
  • Integrity, transparency and professional conduct
  • Written reasoning and communication
  • Role-relevant risk awareness

Each assessment is built from a formal specification that defines:

  • what is being measured
  • why it matters for the role
  • how evidence is collected
  • how responses are scored
  • how fairness, consistency and validity are monitored

This ensures that the assessment is structured, job-relevant and based on observable evidence rather than informal impressions.

Designed using robust psychometric principles

Our assessments are developed using recognised psychometric and assessment design principles. This means we pay close attention to:

1. Clear measurement frameworks

Before any assessment is launched, the capabilities being measured are defined in detail. This includes:

  • the behavioural indicators associated with each capability
  • the types of evidence that support a high, moderate or lower rating
  • the situations or tasks most relevant to the role
  • the scoring rules used to interpret responses

This helps ensure that candidates are assessed against consistent criteria, not subjective opinion.

2. Multiple sources of evidence

No single question, task or response is treated as a complete picture of a candidate. Our tools are designed to collect evidence across multiple methods, such as:

  • situational judgement scenarios
  • forced-choice preference items
  • reasoning and prioritisation tasks
  • ranking or trade-off exercises
  • short written responses
  • structured leadership or role-based questions, where relevant

Using more than one method helps create a more balanced view. It also reduces the risk that a candidate is advantaged or disadvantaged by one specific question type.

3. Realistic, role-relevant scenarios

Assessment content is designed to reflect the kinds of situations people may encounter in senior leadership, sales, commercial, operational or people-management roles. Rather than asking abstract or unrelated questions, scenarios focus on realistic workplace challenges, such as:

  • handling competing priorities
  • making decisions with incomplete information
  • responding to performance issues
  • balancing commercial outcomes with ethical standards
  • influencing stakeholders
  • identifying risk
  • deciding where effort is most likely to create value

This supports content validity: the principle that an assessment should measure things that are genuinely relevant to the role.

4. Structured scoring

Responses are scored using pre-defined scoring models. This may include:

  • credit for more effective or less effective judgement choices
  • partial credit where an answer is reasonable but not optimal
  • structured scoring rubrics for written responses
  • evidence-weighted scoring across different sections
  • checks for consistency across different types of evidence

For written responses, scoring is guided by clear criteria. Where human marking is used, assessors work from structured rubrics to support consistency and fairness.

How we support fairness

Fairness is a core design principle. Our assessments are built to support consistent treatment of candidates and reduce avoidable bias.

Standardised candidate experience

Candidates receive the same or equivalent assessment instructions, timing rules, item formats and scoring criteria. Where different versions of an assessment are used, they are managed through formal version control and calibration processes so that results remain comparable.

Accessibility and adjustments

We aim to make our assessments accessible and practical to complete online. Where candidates require reasonable adjustments or accommodations, these can be managed through the assessment process. Adjustments are handled so that the assessment remains fair while ensuring candidates are not disadvantaged by accessibility needs. The assessment platform is designed to support:

  • online completion
  • autosave and session continuity
  • clear instructions
  • progress indicators
  • responsive display across devices, although a desktop or laptop may be recommended for some exercises

Monitoring for bias and adverse impact

Assessment performance is reviewed using statistical methods once sufficient data is available. This may include monitoring for:

  • differences in item performance across groups
  • adverse impact in outcome bands
  • response patterns that suggest an item may need review
  • reliability of scores over time

Where issues are identified, items or scoring rules are reviewed rather than making automatic assumptions about individual candidates.

Reliability, validity and quality control

Assessment quality is monitored through several layers of scientific and professional governance.

Reliability

Reliability refers to the consistency of assessment evidence. We monitor whether assessment sections and scoring models are producing stable and interpretable results. This may include checks such as:

  • internal consistency of item groups
  • consistency across different methods
  • agreement between trained markers
  • ongoing monitoring of score patterns

Validity

Validity refers to whether an assessment is measuring what it is intended to measure and whether the results are appropriate for their intended use. Our validation approach includes:

  • expert review of assessment content
  • structured item design and scoring rules
  • pilot testing before broader launch
  • review of completion time and candidate experience
  • monitoring of fairness and item functioning
  • comparison with relevant workplace outcomes where available

Assessment results are interpreted as evidence to support decision-making, not as absolute predictions or guarantees.

Pilot testing and ongoing review

Before full use, assessment content is reviewed and tested. This helps confirm that:

  • instructions are clear
  • questions are understandable
  • timing is realistic
  • items perform as intended
  • scoring models produce meaningful results

After launch, assessments continue to be monitored. If evidence shows that an item or section needs refinement, it can be reviewed, updated or retired through controlled governance processes.

Use of technology and AI

Some assessment processes may use technology to support scoring, administration, reporting or quality assurance. Where AI-assisted tools are used, they are governed carefully. Our approach follows these principles:

  • AI does not make unsupported hiring decisions.
  • Human review is used where judgement-based scoring is required.
  • AI-assisted scoring prompts and models are version controlled.
  • Any material change to scoring technology requires review.
  • AI is not used to make prohibited or irrelevant inferences.
  • We do not assess facial expression, accent, voice tone or personal characteristics unrelated to the role.

The purpose of technology is to support consistency, efficiency and evidence quality — not to replace professional judgement.

Data protection and confidentiality

Candidate data is handled in line with data protection requirements, including GDPR principles where applicable. This means we apply:

  • clear consent processes
  • data minimisation
  • secure transmission and storage
  • role-based access controls
  • audit trails for report access
  • defined retention periods
  • separation of personal identity data from assessment response data where appropriate

Assessment data is used only for legitimate assessment, selection, development, validation or research purposes, as described in the relevant privacy notice and consent materials.

Regulatory position, your rights and complaints

Assessment sits within employment, equality and data protection law. This section sets out the regulatory position candidates should be aware of.

Professional and technical standards

Our assessments are developed in line with recognised professional guidance for psychometric testing, including principles reflected in the British Psychological Society's test standards, the International Test Commission guidelines on test use and internet-delivered testing, and equivalent good practice on reliability, validity and fairness. Assessment use, scoring rules and version control are governed internally and reviewed before changes take effect.

Equality and non-discrimination

Assessments are designed to measure job-relevant capability only. Content is reviewed to avoid material that could unfairly disadvantage candidates on the basis of a protected characteristic, and fairness is monitored statistically once sufficient data exists. Reasonable adjustments are available; you can request one before you start and it will not be recorded as part of your result.

Automated decision-making

Some scoring is automated and some written responses are scored with AI assistance. No hiring decision is made solely by automated means. A person reviews results before they are finalised, and you may request human intervention, put your view forward and contest an outcome you believe is inaccurate.

Controller and processor roles

The organisation that invited you is normally the data controller and decides how results are used. Mint Psychometrics normally acts as its processor, handling assessment data on documented instructions under a written data processing agreement.

Your data protection rights

Where UK GDPR or EU GDPR applies you have rights to be informed, to access your data, to have inaccurate data corrected, to erasure and restriction in certain circumstances, to object to processing based on legitimate interests, to data portability, and to withdraw consent where consent was given.

Raising a concern

If you are concerned about how an assessment was administered, scored or used, raise it first with the organisation that invited you, or contact us through the form linked below. If a data protection concern is not resolved, you can complain to the Information Commissioner's Office at ico.org.uk, or to the supervisory authority in your country.

Full detail on the data we hold, why we hold it, how long we keep it and who it is shared with is set out in our privacy notice.

What the assessment is not

To avoid misunderstanding, our assessments are not:

  • clinical or medical tests
  • personality disorder screens
  • surveillance tools
  • lie detectors
  • a measure of personal worth
  • a standalone hiring decision
  • designed to trick candidates

Risk-related indicators, where included, are non-clinical and workplace-focused. They are used to identify areas that may require further discussion, corroboration or review — not to label candidates.

How results are used

Assessment results are intended to support better-quality conversations and decisions. They may be used to help identify:

  • role fit
  • likely strengths
  • potential development areas
  • areas for interview follow-up
  • evidence gaps
  • relevant risk considerations
  • leadership or commercial judgement patterns

Results should be considered alongside other information, such as interviews, experience, references, work history and role-specific requirements. A candidate should not be assessed solely on the basis of one score or one assessment section.

Our commitment to candidates

We are committed to assessment practices that are:

Fair
candidates are assessed against consistent, role-relevant criteria
Evidence-based
decisions are informed by structured behavioural evidence
Transparent
candidates are told what to expect and how the assessment is used
Professionally governed
scoring, reporting and data use are controlled and reviewed
Scientifically responsible
