9-Box Grid: What It Is, How to Run One, and What It Means for Hiring

A 9-box grid is a three-by-three chart that sorts employees by current performance and future potential. It shows a company who's ready to grow, who needs support, and which key roles have no successor yet.

For recruiters, the grid is a preview of which jobs you may be asked to fill next. If a review shows that no one is ready to replace a key manager, that role is likely to turn into an outside search. Knowing how to read the grid, and whether its ratings are sound, lets you plan for those searches early.

What is a 9-box grid?

A 9-box grid is a talent review chart with performance on one axis and potential on the other, each rated low, medium, or high. You may also hear it called a 9-box matrix or a talent matrix. Performance looks back at results in the current role. Potential looks ahead at how well someone could handle a bigger or different role.

The grid wasn't designed for people at first. An expert writing for SHRM notes that it was introduced in the 1970s to help companies prioritize investments across business units. It later became a staple of talent assessment and succession planning. A tool built to sort business units is quick to fill in, which also makes it easy to oversimplify when it's applied to people.

To see how this plays out, take an illustrative case. Say you're recruiting for a regional distribution company that just reviewed its warehouse operations managers. The grid that came out of that review will shape which sites need a successor and which roles may need an outside hire. That's true whether you're the in-house recruiter or an agency partner.

The nine boxes explained

Each box pairs one performance rating with one potential rating, and each pairing suggests a different next step. Labels vary by company, so treat the names below as plain descriptions rather than standard terms. The table also works as a 9-box grid template: copy it into a spreadsheet and swap in your company's own labels.

The top-right box gets the attention, but for a recruiter the gaps are often more useful. Picture one of the distribution sites where the manager sits in the high-performance, low-potential box. Nobody below that manager is rated ready, so no one is lined up to step in.

The low-performance boxes call for a conversation and a plan rather than a final judgment. Someone new to a role may need more time. When results have slipped for a while, a clear performance improvement plan gives the employee specific goals and a fair timeline.

How to run a 9-box talent review

A 9-box talent review works best when everyone agrees on what the axes mean, rates from records, and compares notes before anything is final. The steps below are one way to run a 9-box assessment, so adapt them to how your managers already work.

1. Agree what performance and potential mean for this level: Write a short definition of each axis for the role level before anyone rates a person. For the warehouse operations managers, performance might cover safety, on-time shipping, and team retention. Potential might mean handling a multi-site role.

2. Rate performance from records first: Start with the axis that has the most data, such as results against goals and past reviews. Once performance is settled on paper, it's easier to keep it from blurring into the potential rating.

3. Rate potential with examples: Ask each manager for specific times the person handled something beyond their current role. Structured talent assessment methods, such as work samples or structured interviews, can add more to go on for important roles.

4. Calibrate across managers: Bring the managers together to compare placements, so one person's generous scale doesn't skew the whole grid.

5. Assign an action to every person: Leave the meeting with a next step, an owner, and a date to revisit for each name. Without that, the placements sit in a file until the next review.

The calibration meeting is where the review either holds up or falls apart. A good facilitator asks the same question about every placement: what did this person do that shows it? It's the same habit that makes an interview scorecard useful, because the team agrees on what good looks like before rating anyone.

Even with careful steps, a few problems keep showing up in talent reviews, and most of them sit on the potential axis.

Where the 9-box grid goes wrong

The 9-box grid goes wrong most often on potential, because potential is a forecast and harder to check than past results. One study shows how much weight that rating can carry.

MIT Sloan researchers studied 30,000 management-track employees at one large North American retail chain. Women there got higher performance ratings than men on average but 8.3% lower potential ratings, and they were 14% less likely to be promoted. Moving from medium to high potential came with a 75% rise in the likelihood of promotion, against 27% for the same move on performance. Gender differences in potential ratings could explain up to 50% of the chain's gender promotion gap.

That's one employer, so those percentages don't describe every company. Still, the same research found that women with the same potential scores as men beat their prior year's results. They were still rated lower on potential the next year. The fixes the researchers point to are practical: define what potential means, and have managers justify each score.

The SHRM expert mentioned earlier raises a related concern. In that view, managers often assume today's strong performers will excel in more complex roles tomorrow, which blurs the two axes. The same piece argues that the grid rates people as individuals, so it can miss their impact on a team and their own motivations. It also notes that some people's potential is best realized in a lateral move.

An HR practitioner's post on a SHRM blog describes how this can look in the room. In that view, people who speak up and promote their own work can get read as high potential, though what they're showing is visibility, confidence, and self-advocacy. The post also warns that once someone is calibrated, the label sometimes stays for years. Its fixes are to define potential for each level and function, and to bring performance trends, peer ratings, and project outcomes into the session.

None of this means managers are rating in bad faith. It means the process needs checks, including a look back at whether last year's high-potential labels turned out to be right.

At the distribution company, that might mean asking why a quiet manager at a smaller site sits in the middle while a more visible peer sits top right. Sometimes the placement holds up. Sometimes the quieter manager's results tell a different story.

Those checks matter to recruiters too, because the grid's gaps and labels feed straight into hiring decisions.

How recruiters use 9-box results

Recruiters use 9-box results to see where the bench is thin, which shows which roles may need an outside search. The grid often feeds a company's succession plan, and the gaps in that plan are where your hiring plan starts.

• A key role with no ready successor: If nobody below a critical role sits in a top box, that role is a likely future req. You can start a list of outside candidates now instead of waiting for a resignation.
• A strong performer in a hard-to-fill role: Someone rated high on performance but low on potential may be excellent right where they are. If they leave, there's no one ready behind them, so a quiet pipeline is a sensible hedge.
• High-potential internal candidates: People rated high on potential may get the first look before a role is posted. Ask the hiring manager or client whether an internal move is planned, so you don't run an outside search for a role that's already spoken for.
• A sideways move: When someone is ready for a different function rather than a promotion, the backfill for their current job becomes your search.

Back at the distribution company, remember the site with no one ready behind its manager. Say the review also rated a manager at another site ready for a regional role, which gives you two searches to plan. A talent mapping exercise lets you start the first one before any req opens. The second is the backfill for the manager who moves up, which you can scope now.

Ask about gaps before you start the search

Agency and independent recruiters rarely see a client's grid, but you can still ask what it showed. In-house recruiters can ask a hiring manager the same questions.

• The last review: What did the most recent talent review show for this team, and was this role flagged as a gap?
• Internal candidates: Is anyone inside rated ready for this role, and will they interview alongside outside candidates?
• Why now: Is this a new role, a backfill, or a role that has never had a successor?
• Growth expectations: If the role is a step toward something bigger, what should the new hire be able to grow into?

The answers tell you how wide to search. Pairing that internal picture with talent intelligence on the outside market helps you set realistic expectations with the hiring manager or client. From there, a one-page sourcing plan turns the gap into a search you can start this week.

Check the grid before you open the req

A 9-box grid is only as fair as the definition of potential and the examples behind each placement. For a recruiter, that fairness check shapes the work directly. The gaps on the grid become your reqs, and the high-potential labels decide who gets the first look before you search outside. So before the next req opens, ask the hiring manager or client what the last review found and how they decided who was ready.
