Talent assessment: methods, tools, and best practices for HR

Knowing the ability levels of your talent is essential in order to move forward in business. It’s no good just having a grasp of what your workforce can do now, it’s a case of understanding workforce capability, leadership readiness, future potential, skill gaps, and redeployment opportunities before any critical decisions are made. 

A 2026 Careerminds study found that 40.6% of companies said they would have benefited from more data on employee capabilities and skills when making workforce decisions. The same study found that many organisations later regretted AI-led workforce reductions, because they lacked a clear understanding of the talent already inside their business.

This is where talent assessment comes into play. The message to HR leaders and business executives is clear – if you can’t accurately assess your talent, then you can’t accurately plan your workforce.

Talent assessment evaluates employees against predefined criteria to understand their knowledge, skills, behaviours, performance, and potential career development. Companies use talent assessment processes throughout the lifecycle of each employee, including:

• Recruitment and selection.
• Internal mobility.
• Succession planning.
• Leadership development.
• Workforce planning.
• Redeployment during a restructuring process.
• Learning and career development.

The idea is to replace subjective judgement with evidence-based decision-making. Rather than asking, “Who looks like they might be ready for a promotion?”, talent assessment gives up data that helps answer the following questions:

• Which member of staff has the skills required?
• Who will develop in future roles?
• Where are there capability gaps?
• Which employees could be reskilled instead of replaced? 

Traditional talent management processes are not keeping up with the pace of change across the UK workplace. According to the CIPD, a few trends are increasing the importance of talent assessment, with skills and capabilities central to succession planning, organisational productivity, sustainability, and future growth. To remain competitive, companies need to fully understand current and future capability requirements. 

The 3 main trends being noticed are:

1. Skills shortages

UK employers continue to report difficulties in filling skilled roles. An employer skills survey, conducted by the UK government, found that 27% of all vacancies in 2024 were classified as skill-shortage vacancies, down from 36% in 2022, but higher than 22% in 2017. As skills become more specialised, organisations need better visibility of what existing workforce capabilities they have within the business before turning to external recruitment.

2. AI-driven transformation

AI is reshaping jobs, skill requirements, and workforce structures. Companies are trying to find employees who are able to combine technical expertise with critical thinking, adaptability, communication, and problem-solving skills. If data isn’t assessed correctly, this can lead to poor workforce decisions which will bring about unnecessary costs to the business. 

3. Better workforce planning

When organisations understand workforce capability, they can:

• Identify future skills gaps.
• Build succession pipelines.
• Improve internal mobility.
• Reduce unnecessary recruitment.
• Minimise regrettable attrition.
• Make more informed restructuring decisions.

The best talent strategies combine multiple tools, as no single method gives an overall picture of employee capability.

Competency assessments measure the behaviours, skills, and attributes that are linked to successful performance, such as leadership capabilities, customer focus, strategic thinking, collaboration, and adaptability. Competency frameworks create consistency across recruitment, performance management, and development processes.

They are best for:

• Leadership development.
• Succession planning.
• When making internal promotion decisions.

Skills assessments evaluate technical and functional expertise, such as digital skills assessments, code testing, financial and data analysis, project management simulations, and language proficiency.

They are best for:

• Recruitment.
• Workforce planning.
• Reskilling initiatives.

Psychometric tools measure personality traits, preferences, motivations, and cognitive abilities, taking the form of personality questionnaires, numerical reasoning tests, verbal reasoning, and situational judgement tests.

They are best for:

• Identifying leaders.
• Team effectiveness.
• Recruitment screening.

Cognitive assessments evaluate how effectively individuals learn, analyse information, solve problems, and make decisions. Cognitive ability is top of the list when it comes to being a strong predictor of future job performance.

They are best for:

• Graduate recruitment.
• Leadership pipelines.
• Identifying high-potential candidates.

Assessment centres combine multiple exercises, such as presentations, group discussions, role play, business simulations, and interviews. They remain one of the most robust methods for evaluating leadership potential and management capabilities.

They are best for:

• Selecting leaders.
• Senior hiring.
• Succession planning.

This method gathers feedback from managers, peers, direct reports, and stakeholders, and provides a broader perspective than manager-only evaluations.

They are best for:

• Leadership development.
• Coaching.
• Behavioural assessments. 

Performance reviews assess the current contribution of each employee, i.e. how they’re doing now, while potential assessments evaluate future capabilities. Together, they help to identify employees who could be ready for broader responsibilities.

They are best for:

• Talent reviews.
• Succession planning.
• Career frameworks.

Let’s look at a clear way of building a talent assessment framework that can be adapted to your own business. This structured framework will help assessment activities to drive business outcomes.

Step 1: Define your business objectives

Begin with workforce priorities, such as cementing leadership pipelines, identifying future skills, supporting succession planning, improving internal mobility for staff, and restructuring the workforce.

Step 2: Create a competency framework

Define the skills that are required for success, such as core competencies, technical competencies, leadership competencies, and future skills.

Step 3: Select the appropriate assessment methods

Using multiple methods reduces bias and improves validity, so incorporate a mix including skills testing, psychometric testing, performance reviews, manager assessments, and 360 degree feedback.

Step 4: Calibrate assessment standards

Ensure there is a consistency to how managers apply criteria, so that calibration sessions reduce subjectivity and improve fairness.

Step 5: Centralise data with technology

Assessment results should connect with talent reviews, workforce planning tools, learning systems, and succession planning.

Step 6: Review and refine

Assessment frameworks should grow alongside business strategies and workforce needs.

• Link each assessment activity directly to a business strategy.
• Combine multiple assessment methods.
• Focus on future skills, not just current performance.
• Review assessment validity on a regular basis.
• Train managers to assess consistently.
• Audit processes for bias and fairness.
• Integrate assessment data into workforce planning.
• Use AI responsibly, with appropriate human oversight.
• Communicate clearly with employees about how the assessment data will be used.

There’s no ignoring how influential AI is now across talent assessment, as it transforms how companies approach it. Positive additions include analysing AI-assisted interviews, identifying skills gaps, modelling workforce scenarios, and pulling skills inferences from employee data. AI is great for improving efficiency and uncovering workforce insights that would have remained hidden.

But it should complement human judgement, not replace it. HR leaders must remain transparent and use

human oversight, so any bias can be monitored and fairness testing is carried out. The most effective organisations use AI to seek out the possibilities, while people remain at the heart of final decisions.

All UK organisations must ensure that their talent assessment practices comply with employment law and equality obligations under UK laws.

The Equality Act 2010 is there to protect people from being discriminated against based on protected characteristics, such as age, gender, disability, and race. If applied talent assessment methods, such as biased psychometric testing or inaccessible assessment formats, disadvantage these protected groups, this will expose organisations to legal risk.

The Chartered Institute of Personnel and Development (CIPD) strives for fair and evidence-based assessment practices that are relevant to the role, objective, consistent, transparent, and inclusive.

If you’re going to use AI in talent assessment processes, you should conduct bias testing, monitor the outcomes across demographic groups, maintain human oversight, and document all decision-making processes.

Transparent and fair assessments are vital to sustain organisational trust and employer reputation.

The 9 box grid is a talent management framework that assesses employees against performance and potential. The grid is a 3 x 3 table, resulting in 9 boxes, with each box representing a combination of performance and potential levels – low, medium, or high. 

Employees are placed into 1 of 9 categories, ranging from low performance / low potential to high performance / high potential. This framework helps organisations to identify potential leaders, prioritise development investment, and guide career conversations in the right direction.

The 5 Cs of talent are a common framework used to evaluate workforce capability: 

Competence – the knowledge and skills required to perform a role effectively.

Commitment – the motivation and engagement that an individual brings to their role.

Character – personal integrity, ethics, and reliability.

Capacity – the ability to handle increasing complexity and responsibility.

Culture fit or contribution – how effectively an individual aligns with, and enhances, organisational values and ways of working.

A bonus is:

Collaboration – to be able to work well with, and get along with, other members of the team, by being able to knowledge-share and provide support.

Assessing potential is about evaluating an individual’s ability to succeed in larger, more complex roles, rather than just how they are performing in their current position. It’s looking at what someone could achieve if they were given the opportunity with the right development. 

Using a combination of talent assessment methods can help to identify those certain qualities that are associated with future success, such as adaptability, resilience, emotional intelligence, resolving problems, and leadership capacity.

A performance review focuses primarily on evaluating an employee’s past and current performance, while talent assessment looks at an individual’s capabilities, behaviours, and future potential.

Performance reviews assess how effectively someone has achieved their objectives over a specific period of time, taking into account factors such as productivity, work quality, and overall contribution to business goals. The emphasis is on what has already happened.

Talent assessment, on the other hand, is forward-looking, using tools to understand current capabilities along with future possibilities. Effective organisations use both approaches.

AI is used in talent assessment, particularly by companies looking to make faster, more data-driven workforce decisions. AI should be used to support HR teams by analysing large volumes of employee and candidate data that would, otherwise, take a long time to assess manually. 

AI platforms can highlight individuals who will be suited to new roles or development opportunities by analysing employee profiles, learning records, performance data, and career histories, but it must be used responsibly, with UK employers ensuring assessment practices remain fair, transparent, and compliant with the Equality Act 2010.

AI is transforming the talent assessment landscape by enabling organisations to evaluate skills, capabilities, and potential at a scale that was previously unheard of. 

Traditional talent assessments relied heavily on manager observations, annual reviews, and manual data collection. AI allows HR teams to combine and analyse information from multiple sources to create a more rounded view of workforce capability, combining AI-powered insights with informed human judgement.

Talent assessment is a critical part of the HR skillset. The businesses that flourish over the next 10 years will be the ones that understand their workforce best – and can spot capability before their competition does.
