How Should You Assess Senior Leaders? Why One Test Is Not Enough
How Should You Assess Senior Leaders? Why One Test Is Not Enough
Senior leadership decisions are too consequential to rely on one narrow source of evidence.
A senior leader may need to think strategically, make decisions with incomplete information, influence stakeholders, lead through ambiguity, develop others and understand the commercial, technical or policy environment in which they operate.
No single test, interview or simulation can answer all of those questions.
But there is an equally important warning: more assessment does not automatically mean better assessment.
The goal is not to create the longest possible battery of tests. It is to define the questions that matter, choose appropriate methods to answer them, and integrate the evidence against a clear role, competency framework or success profile.
Before choosing an assessment method, define the decision.
Are you selecting a senior leader, considering a promotion, identifying successors, evaluating high-potential talent or supporting development?
These decisions are related, but they are not the same.
Research on senior-leader assessment distinguishes between assessments designed to support organizational decisions and those designed primarily for development. Evidence gathered for one purpose should not automatically be assumed suitable for another.
ISO 10667-1:2020 reinforces this focus on purpose. The international standard for work-related assessment addresses assessment rationale, choice and implementation of methods, professional competence, use of results, and principles such as validity, reliability, fairness and standardization.
The first question, therefore, should not be:
“Which test should we use?”
It should be:
“What decision are we trying to make, and what evidence do we need to make it well?”
Psychometric assessments can provide valuable standardized evidence when the candidate attributes being measured are relevant to the role and the tools are appropriate for their intended use.
Personality questionnaires may provide insight into characteristic behavioral tendencies. Cognitive assessments can provide evidence about aspects of reasoning and information processing. Measures of values may also be relevant where they have a defensible connection to the role.
Research supports links between personality characteristics, cognitive abilities and aspects of work performance, although those relationships vary by candidate attribute, criterion and context.
For all candidates, especially senior leaders, psychometrics should be treated as one source of evidence, not a verdict.
A personality profile does not determine leadership potential. A cognitive score does not establish executive readiness.
Their value comes from answering specific questions and being interpreted alongside other relevant evidence.
Behavioral simulations answer a different question:
What does the person actually do in a relevant situation?
Examples might include:
These simulations can provide evidence about judgement, prioritization, communication, influencing and handling challenges.
Their usefulness depends on good design, job relevance, standardization, clear behavioural criteria and capable assessors.
But they offer something self-report measures cannot provide on their own: an opportunity to observe behavior as it occurs.
This distinction matters because “Assessment Centre” is sometimes used as a general label for almost any organized assessment event.
Professionally, it refers to a specific methodology.
The 2015 Guidelines and Ethical Considerations for Assessment Center Operations, produced by the International Taskforce on Assessment Center Guidelines, describe an Assessment Centre as a standardized evaluation involving multiple assessment components, multiple trained assessors, behavioral simulations and systematic integration of observations and ratings.
The guidelines also make clear that processes relying on a single assessment component or a single assessor should not be described as Assessment Centers.
A recent conversation illustrates the point.
An organization described its supervisor process as an “Assessment Centre”. When we explored what happened, participants essentially completed one simulation and then received a report.
That may be a perfectly legitimate and useful assessment simulation.
But a single simulation followed by a report is not, by itself, an Assessment Centre under established professional guidelines.
This does not mean the organization’s process was ineffective. We would need evidence before making that judgement.
The point is simply that terminology matters.
An Assessment Centre is a methodology, not just an assessment event.
Nor does every senior leadership assessment need an Assessment Centre. The methodology should follow the decision.
Multiple trained assessors are a defining feature of Assessment Centre methodology.
Their purpose is not to remove bias entirely. Multiple assessors do not make judgement infallible.
Rather, they reduce dependence on one person's interpretation and allow observations to be compared and integrated more systematically.
Assessor training, behavioral criteria, structured recording and calibration are therefore important.
The final integration or “wash-up” involving multiple assessors discussing the results, should also focus on documented behavioral evidence rather than informal impressions.
Structured interviews remain highly valuable in leadership assessment.
But a structured, competency-linked interview is very different from an informal executive conversation.
A structured interview starts with defined criteria, uses a consistent approach and evaluates evidence against predetermined scoring principles.
This helps reduce reliance on rapport, familiarity or interviewer intuition.
The lesson is important: no single method should be treated as infallible.
Leadership capability does not always compensate for insufficient specialist knowledge.
Some senior roles require a defined level of professional, regulatory, technical or commercial expertise.
Where that knowledge is genuinely important to successful performance, technical or job-knowledge assessments can add useful evidence.
But they should be included because the role requires them, not simply because another assessment feels desirable.
360-degree feedback provides another perspective: how a leader's behavior is experienced by managers, peers, direct reports and other stakeholders.
That can make it highly valuable for leadership development, self-awareness and development planning.
But 360 feedback should not automatically be treated as equivalent to a high-stakes selection instrument.
Research on senior-leader assessment highlights the tension that can arise when the same data are used both for development and organizational decision-making. Coworkers may respond differently when they believe feedback will influence a promotion or selection decision.
Purpose, confidentiality and governance therefore matter.
Multi-method assessment should not become assessment by volume.
If five tools largely assess the same interpersonal characteristic while failing to assess strategic judgement, the organization may have collected more data without gaining better evidence.
For every method, ask:
What does this uniquely contribute?
Multi-method assessment should be about coverage and complementarity, not accumulation.
This is where otherwise sophisticated processes can become fragmented.
Five separate reports do not automatically create one coherent leadership assessment.
A strong approach starts with the role requirements or success profile and maps each assessment method against the competencies or constructs it is intended to measure.
The process should define:
Contradictory evidence should not necessarily be averaged away. Differences between what somebody reports about themselves and how they behave in a simulation may themselves be informative.
Integration is not an administrative afterthought. It is central to the quality of the assessment process.
A buyer's checklist for senior leadership assessment
Before commissioning or redesigning a leadership assessment process, ask:
Better leadership decisions require better-integrated evidence
Senior leadership decisions deserve more than one narrow lens.
But the answer is not simply more tests.
Strong leadership assessment combines the right evidence, gathered in the right way, by appropriately trained people, and integrated against a clear understanding of what success requires.
Sometimes that will include psychometrics. Sometimes structured interviews, simulations or knowledge assessments will add important evidence. A 360 process may be highly valuable for development. For some decisions, a properly designed Assessment or Development Centre may be appropriate.
For others, it may not.
What matters is whether the organization can explain why each method is being used, what question it answers and how the evidence contributes to the final decision.
