A 9-box talent review is a 3-by-3 grid that places employees by current performance and estimated future potential, so managers and HR teams can structure conversations about development and succession. The placement is a discussion aid. It does not prove that someone will succeed in a bigger job, and it does not fix a person’s label for good.
What a 9-box talent review is
The 9-box talent review (often called the 9-box grid or 9-box matrix) plots each employee on two dimensions: how well they are doing in their current role, and how much they appear able to grow into more complex or different work. Each dimension is usually split into low, moderate and high bands, which produces nine possible combinations. Teams use the grid to compare people side by side, to spot where succession gaps may be, and to decide which conversations about development should happen first.
The model has a longer history than its current use suggests. In a SHRM article dated May 1, 2025, John Hazan, global leader of Bain & Company’s Talent solution, writes: “The 9-box matrix was originally introduced as a way to help companies prioritize investments across different business units.” In other words, the grid was designed as a portfolio tool for allocating attention and money, and was later applied to individual people. That origin is one reason its categories are often vague when applied to a single employee.
The grid: two axes and nine cells
Most organisations draw the grid with performance on one axis and potential on the other. Which axis sits on the vertical and which on the horizontal varies, and so do the names given to each cell. The table below shows the structure in neutral terms; it is not a universal set of labels.

|---|---|---|---|
| High potential | Moderate combination: strong growth signals, but current results are below expectation | Moderate combination: strong growth signals with solid current results | High-high: the combination SHRM describes as the highest ranking |
| Moderate potential | Moderate combination: current results need attention before growth is judged | Moderate combination: the core of most teams | Moderate combination: strong current contributor whose growth path is still being tested |
| Low potential | Low-low: SHRM describes this as the lowest ranking | Moderate combination: stable contributor where growth capacity is judged limited for the roles reviewed | Moderate combination: strong current results without clear evidence of capacity for more complex work |
Two points follow from the table. First, the middle cells carry most of the real judgement, because most employees land there and the grid says little about their next step. Second, a cell describes a pattern of assessments at one moment. It is not a personality type.
Performance and potential measure different things
Performance describes how someone is doing in the job they hold now. Potential describes their capacity to grow, to take on broader responsibility, or to succeed in different or more complex work. CIPD guidance on performance management and AIHR’s 9-box guide both treat these as separate judgements that need separate evidence.
The separation matters because strong current performance is easy to mistake for readiness. A skilled analyst who delivers excellent work may be a poor fit for a people-management role, and a manager who runs a team well may not yet have the commercial judgement a director role requires. Hazan’s SHRM article puts the problem bluntly: “The distinction between performance and potential is often unclear.” When that line blurs, the grid tends to reward whoever is most visible, not whoever is most suited to the next job.
Defining potential before placing anyone
Potential is more abstract than a sales figure or a delivery record, so it needs a written definition before anyone is placed. AIHR’s guide asks, “What does potential look like in your organization?” That question has to be answered for specific roles. A useful definition names the capabilities or behaviours required for the next role, a broader remit, or a different career path, and states what evidence would show them.

Potential is not the same as ambition, and it is not the same as current performance. An employee who asks for promotion every quarter may have low demonstrated capacity for the next level, and a quiet, consistent specialist may have a clear track record of learning fast. Keeping these separate prevents the review from measuring confidence or self-promotion.
Running a review, step by step
- Set the purpose first. Tie the review to business and workforce needs, such as development plans or succession for critical roles. CIPD’s “Talent management” guidance (dated November 26, 2025) frames talent management as something that should align with organisational strategy, not as an annual ritual.
- Write down what potential means for each role group. Use the definition described above and agree it among reviewers before ratings begin.
- Collect evidence from more than one source. Use manager observations, performance records, peer and team input, and employee aspirations. CIPD’s guidance on performance management fairness describes using data beyond the line manager’s view, and comparing machine and manager ratings as a prompt for a better conversation rather than a verdict. Treat any algorithmic score as one input that may need scrutiny.
- Ask the same questions of every employee. AIHR recommends consistent questions and consistent evidence for ratings, so that two managers assessing similar people are working from the same standard.
- Place people provisionally. Record placements as working drafts, not final decisions. The calibration step below is where drafts are tested.
- Check for patterns. Look at whether high-potential placements cluster in particular teams, locations, or demographic groups, and ask whether that reflects real differences or uneven opportunity. CIPD describes inclusion and diversity as considerations in succession planning.
- Convert placements into actions. Each placement should lead to a development step, with an owner and a review date. Details are in the development section below.
Calibration and bias
Calibration means reviewers compare their placements against shared criteria and challenge each other’s assumptions with evidence. A manager who rates a team’s output consistently high may be applying a more generous standard than a peer whose team delivers similar results with fewer resources. Calibration sessions are where that difference surfaces.
Several biases are commonly discussed in this context. Visibility bias favours people who present work to senior leaders. Halo effects let one strong quality colour the whole rating. Recency effects give too much weight to the last few months. The CIPD Guidance piece on the 5HR02 talent-management content (a secondary commentary, not an official CIPD standard) describes calibration and provisional placements as sound practical steps; they are worth adopting because they are cheap to run, not because they guarantee fairness.
Readiness is a separate question
Potential answers whether someone could grow into future work. Readiness answers whether they are ready for a specific role now. CIPD’s performance-management material describes readiness and role criticality as additional succession dimensions, and AIHR explicitly advises separating growth potential from immediate promotion readiness.

In practice this means a high-potential employee may be two years from readiness for a particular role, and a moderate-potential employee may be ready for a lateral move that suits their strengths. A succession decision for a critical role needs a readiness assessment. A general potential placement does not supply one.
What the grid cannot tell you
The grid makes it easier to see a group’s assessments together. It can prompt useful discussion. It does not show that a high-potential employee will succeed in a different role, that a low-potential rating is permanent, or that the same criteria were applied fairly to everyone. SHRM identifies three limitations that are worth keeping in view: the ambiguity between performance and potential, the subjectivity of evaluation, and the omission of team contribution and personal aspirations. Hazan argues that the traditional grid can miss these dimensions, and that a broader review should also consider business needs, how someone helps their team succeed, and what the individual wants from their career.
A lateral move, deeper specialist expertise, or a different role may also fit a person and the business better than upward progression. The standard grid does not show those paths, so they need to be raised explicitly.

CIPD’s talent-management guidance lists coaching, mentoring, training, secondments and networking as talent-development activities. The placement itself does not develop anyone. A good review ends with a named action for each person, such as a stretch assignment, a mentor from another team, a formal training course, or a secondment, plus a date to check progress. Ratings are snapshots, not permanent labels, so each one should be reviewed when evidence, roles or organisational needs change.
If you are the one being placed
Whether or not your organisation uses the grid, these questions help you understand a placement and make it useful:
- What definition of potential is being applied to my role, and what evidence does it use?
- Was my placement agreed in calibration, or was it a single manager’s view?
- Is the review about growth potential, immediate readiness for a particular role, or both?
- What development step follows from it, who owns that step, and when will it be checked?
- Have my own aspirations, including a lateral or specialist path, been recorded?
Asking these questions in a calm, specific way tends to produce more useful answers than contesting a box.

Labels and cell names differ between organisations, so check the criteria your own organisation uses before reading a placement as a verdict.
