Most managers can tell you who is performing well right now. Far fewer can tell you who has the capacity to grow significantly beyond their current role. The two are not the same thing, and conflating them is one of the most common development mistakes a manager makes. You end up promoting your best individual contributor into a role they are not ready for, or you miss the quiet member of the team who is two years away from being outstanding.
Identifying high-potential employees is a skill. It takes structured thinking, evidence, and calibration with others. Done well, it gives you a clearer picture of where your team is heading and what investment will pay off most. Done badly - or not at all - you make development decisions on gut feel and lose talented people who felt overlooked.
Performance is what someone delivers today. Potential is their capacity to deliver significantly more tomorrow. You need to track both, because they call for completely different conversations.
Performance vs potential: why the distinction matters
A high performer delivers excellent results in their current role. They know the work, execute reliably, and meet or exceed expectations consistently. High performance is visible, measurable, and relatively straightforward to assess. A high-potential employee has the capacity to grow significantly beyond their current role - into a larger scope, a leadership position, or a fundamentally different kind of contribution.
Someone can be an exceptional individual contributor with limited appetite or capability for broader leadership. That is fine, and it does not mean they should receive less investment. But if you are thinking about succession planning, future team leadership, or building the organisation for the years ahead, you need to assess the two dimensions separately.
The four talent segments
High performance, high potential
Strong now, strong trajectory. Prioritise for stretch assignments and accelerated development.
Low performance, high potential
May be in the wrong role, under-supported, or early in development. Investigate before writing them off.
High performance, low potential
Excellent in their lane. Develop depth, not breadth. Avoid promoting into roles that do not suit them.
Low performance, low potential
Address the performance gap first. This may call for a PIP or a role change rather than a development conversation.
Most teams have all four segments. Knowing which quadrant each person sits in changes what you prioritise in development conversations.
The risk of using performance as a proxy for potential is that you end up promoting people who are excellent at what they currently do into roles where those skills are no longer the primary requirement. The most common example is the best individual contributor becoming a team lead, only to struggle because leadership requires a completely different set of behaviours. Identifying potential means looking for those behaviours, not just current output.
What high potential actually looks like
Potential is not a single trait. It is a cluster of behaviours and attributes that predict how effectively someone will grow, adapt, and contribute at a higher level. The research on this is fairly consistent, even if the language varies from organisation to organisation. Here are the markers worth paying attention to.
- Learning agilityDo they pick up new skills quickly, adapt to unfamiliar situations, and apply lessons from failures? Learning agility is the strongest single predictor of future leadership potential. Look for people who actively seek feedback, experiment, and reflect rather than defaulting to what they already know.
- Drive and initiativeDo they identify problems and solve them without being asked, or do they wait for direction? High-potential employees tend to operate ahead of their job description. They take on things that need doing, even when they are not formally responsible.
- Emotional intelligenceCan they read the room, manage their own reactions under pressure, and adapt their communication style to different people? This matters more as scope increases. Strong individual contributors can get by on technical skill alone; effective leaders cannot.
- Influence without authorityDo people follow their lead even when they have no formal mandate? Someone with high potential often shapes decisions and direction through credibility and persuasion rather than seniority. Watch how they behave in cross-functional settings.
- Comfort with ambiguityDo they find unclear situations destabilising, or do they create structure from them? Senior roles involve more ambiguity, not less. The ability to stay effective when direction is unclear is a reliable differentiator.
- Curiosity about the bigger pictureAre they interested in how their work connects to the wider goals of the organisation? Do they ask questions about strategy, customers, or the business context of what they are building? Curiosity about scope is a leading indicator of readiness for broader responsibility.
None of these markers show up every day in every context. Look for patterns across multiple situations and time periods, not a single impressive moment. One standout presentation does not tell you much. Five months of consistently doing the right things when no one is watching tells you a great deal.
How to assess potential fairly
The biggest risk in talent assessment is gut feel. It produces biased outcomes, rewards people who seem confident, and disadvantages those who are quieter, newer, or different from whoever is doing the assessing. The way to counteract this is to make your criteria explicit before you assess anyone, and then calibrate your judgements with others.
A structured assessment approach
Define the criteria
Agree with your peers which behaviours you are assessing for, before you look at any names.
Gather evidence
Use 1:1 notes, project outcomes, peer feedback, and retro observations - not just your recent impressions.
Rate each person individually
Score each person against the criteria before any group discussion, to avoid anchoring on others' views.
Calibrate with peers
Compare ratings with other managers. Where there are gaps, investigate the evidence rather than averaging.
Review for bias
Ask: does the high-potential list reflect the diversity of the team? If not, examine why.
One useful proxy test: ask yourself, would I want this person to manage someone I cared about? It forces you to consider whether you are assessing leadership capability or just technical excellence. Another useful check: if this person left tomorrow, would you be surprised? If yes, they are probably worth assessing more carefully.
Calibration sessions with peer managers are especially valuable because they surface blind spots. Your high performers may be invisible to other managers; your high-potential employees may already be seen as future leaders across the organisation. Both are useful signals. Use 1:1 notes and project histories in Manager Toolkit to pull together evidence before these conversations so you are not relying on recent memory alone.
What to do once you identify high-potential employees
Identifying potential without acting on it is worse than not identifying it at all. If someone knows they have been assessed as high potential - or suspects they have - and nothing changes, the message they receive is that it does not matter. Here is where the investment needs to go.
- Tell themMost high-potential employees are never told. This is a mistake. Having an honest conversation about how you see their trajectory builds trust, focuses their development, and signals that you are investing in them. You do not need to make promises about timelines or roles; you do need to be direct about what you see and what it means.
- Create stretch assignmentsStretch assignments are among the most effective development tools available. Give them a project that is a size too big for their current role: something that requires them to lead without authority, manage complexity, or navigate a new domain. The discomfort is the point.
- Build a development planWork with them to create a development plan with specific goals tied to the behaviours you are trying to develop. Vague plans produce vague results. Specific ones - "lead the technical design for Q3 and present it to senior stakeholders" - produce evidence.
- Increase their visibilityOne of the things that limits high-potential employees is being invisible beyond their immediate team. Bring them to leadership meetings as appropriate, involve them in cross-functional projects, and introduce them to senior stakeholders. Visibility accelerates development because it creates both opportunity and accountability.
- Find them a mentor or sponsorA mentor offers guidance and perspective from outside the immediate management relationship. A sponsor actively advocates for them in rooms they are not in. Both are valuable. Senior people rarely volunteer for these roles unprompted; you usually need to make the introduction.
In Manager Toolkit, you can create a Target for each development goal and track progress over time. Connect the Target to Catchup notes from your 1:1s so the conversation history sits alongside the goal. When you reach the next review, you have a clear record of what was agreed, what was attempted, and what the outcome was - not just a vague impression of how the period went.
Common mistakes to avoid
Even managers who take talent assessment seriously often fall into the same traps. These are the ones that show up most often and cause the most harm.
- Confusing confidence with capabilityConfident people are easier to identify as high potential because they take up more space in conversations. Quieter, more reflective people with equal or greater potential get missed. Looking for evidence of each marker explicitly, rather than relying on presence, helps correct for this.
- Keeping it secretKeeping potential assessments confidential for calibration discussions is sensible. But if you never tell someone they are high potential, you deprive them of direction and motivation. You also make them vulnerable to being recruited away by someone who will tell them.
- Promoting before developingIdentifying high potential and immediately giving someone a promotion or senior title is a common mistake. Potential needs developing before it becomes reliable. Promote based on demonstrated readiness, not assessed potential alone.
- One assessment, no follow-upPotential is not a fixed trait. Someone assessed as high potential two years ago may have plateaued. Someone overlooked may have grown significantly. Revisit your assessments at least annually and update them based on evidence, not memory.
- Neglecting the rest of the teamFocusing disproportionately on high-potential employees while neglecting everyone else is a morale risk. Every member of the team deserves a development conversation. The difference is the ambition of the goals and the depth of the investment.
The managers who develop talent most effectively are not the ones who identify potential fastest. They are the ones who follow through: building structured plans, having honest conversations, creating stretch opportunities, and revisiting their assessments regularly. Identification is the starting point, not the end.
