What is a 9-box grid?

Definition

A 9-box grid is a three-by-three matrix used in talent reviews and succession planning. One axis rates an employee's current performance, usually low, moderate or high; the other rates their potential to take on a larger or different role. Each person lands in one of nine boxes, from low performance and low potential in one corner to high performance and high potential in the other.

The grid is useful because it separates two questions that ratings often blur. A strong performer in their current role is not automatically ready for the next one, and someone still growing into a role may have a great deal of headroom. Placing people on both axes makes that distinction explicit and gives a talent review a shared picture to discuss.

It is also called the nine-box, the performance-potential matrix or simply a 3x3 talent matrix. Some organisations use a two-by-two or a four-by-four instead, but the three-by-three version is the one most people recognise.

How it works in practice

Before placing anyone, the group agrees what each axis means. Performance is usually taken from the latest review rating, so it rests on evidence already gathered. Potential needs a written definition — commonly a mix of ability to learn, aspiration for a larger or different role and behaviours that would scale — so that two leaders mean the same thing when they call someone high potential.

Managers propose placements for their people before the talent review, and the meeting tests them: why this box, what evidence supports it and what would move this person. Each box carries a typical response — stretch and succession consideration for high performance and high potential, development in role for strong performers with less appetite to move, closer support for low performance — and the output is an agreed action for each person, not just a position on the grid.

Placements are usually revisited once a year, aligned to the review cycle, with a lighter check when something changes materially, such as a new role or a completed stretch assignment.

A worked example

An illustrative example: the team described is hypothetical, not a customer.

Consider a hypothetical finance function reviewing twelve people. An accounts manager with consistently strong review results and a stated wish to lead a larger team is placed in high performance, high potential, and named as a successor for the financial controller role. A payroll specialist with equally strong results, who has said they want to deepen their expertise rather than manage, is placed in high performance, moderate potential.

The two receive very different plans. The accounts manager takes on a cross-team project to build the leadership competencies the controller role requires, while the payroll specialist is recognised, offered specialist training and kept in role. A newer analyst who is still learning the role but picking it up fast is placed in moderate performance, high potential, and given a mentor. Without the second axis, the first two would have looked identical.

Common mistakes

Confusing potential with performance. The strongest performers are not automatically the people with the most potential for a different role, and the grid is useful precisely because it keeps the two apart.

Placing people from memory. Without review results and competency evidence on the table, the grid records the opinions of whoever knows the person best, or speaks most confidently.

Treating the box as a label. A placement is a snapshot for planning, not a permanent verdict, and box names that sound like judgements tend to stick to people long after their circumstances change.

Stopping at the grid. If the meeting ends with a completed grid and no agreed action for each person, the exercise has produced a picture rather than a plan.

How CLEAR Talent supports it

A placement is more defensible when performance comes from review scores and potential is discussed against competency data. In CLEAR Talent's succession planning software the 9-box is interactive, its axes are configurable, and every move is written to an audit log. Readiness ratings then turn a box into a development conversation, drawing on the same competency assessments used in reviews.
