The 9 Box Grid Secret Nobody Talks About: Why Hiding Talent Ratings Is Costing You Your Best People

There is an unwritten rule in most talent review processes: the ratings stay in the room. 

HR leaders and senior managers spend days assessing, debating, and calibrating where each employee sits on the 9 Box Grid. Then the session ends, the grid is filed away, and the employee, the person at the centre of the entire exercise, is told nothing. 

The reasoning is well-intentioned. Share a "high potential" rating and you risk creating expectations you can't deliver on. Share a lower rating and you risk demotivating someone who is actually performing well. Better, the thinking goes, to protect people from a label they might misinterpret. 

But here is what that logic misses. By the time you have decided not to share the rating, the process has already failed. And the cost of that failure is sitting in your talent pipeline right now. 

The Data Was Wrong Before the Meeting Even Started 

When a manager assesses an employee's potential and career readiness without ever having a genuine conversation about what that employee actually wants, the assessment is not objective. It is a guess. 

Does this person want to move into a leadership role? Do they want to deepen their expertise where they are? Are they interested in a lateral move, or are they quietly considering leaving altogether? These are not small details. They are the most important inputs in any talent assessment, and in a process built around the 9 Box Grid, they are almost never gathered systematically, because the process is designed around rating, not conversation. 

The result is a talent grid populated with data that reflects what managers think about employees, not what is actually true about them. The moment you accept that ratings are withheld to avoid raising expectations, you are also accepting that the data underpinning your succession plan is built on assumptions. 

That is not a minor technical flaw. It is a structural one. 

While You Were Calibrating, Your Competitor Was Having a Different Conversation 

Here is what happens in parallel while the talent review cycle runs its course. 

The manager attends calibration sessions. HR consolidates ratings. Senior leaders debate the grid. The whole process takes weeks. And at no point in any of it is the employee asked about their career aspirations, told what the organisation thinks of them, or given any meaningful development opportunity connected to their potential. 

What the employee does experience is a performance review, often backward-looking and focused on last year's delivery, followed by silence. No clarity on where they stand. No conversation about where they are headed. No development aligned to what they actually need. 

Disengagement does not announce itself. It accumulates quietly. And the employees most likely to disengage are often the ones rated highest on your grid, because they have the most options and the least tolerance for feeling invisible in a process that is supposedly about them. 

By the time your talent review is complete and the grid has been calibrated, some of those employees will have already had a conversation with your competitor. Not because they were unhappy, necessarily. But because your competitor asked them what they wanted. And you didn't. 

The Expectations Problem Is Real. But You Are Solving It the Wrong Way. 

The fear of raising expectations is legitimate. If you tell someone they are "high potential" without any clarity on what that means, what development they will receive, or what a realistic timeline looks like, you have created a problem. The label does the damage, not the transparency. 

But the solution to that problem is not secrecy. It is a better process. 

The reason the 9 Box Grid creates expectation problems when shared is that it is a label, not a conversation. "High potential" is a static categorisation that carries enormous emotional weight but offers no actionable information. Of course it raises expectations. It was never designed to do anything else. 

A process built around career stages rather than performance-potential labels changes this. When an employee understands that they are in a "Stretch" stage, preparing for a larger or more complex role in the near term, that is meaningful and specific. It tells them where they are. It tells them what comes next. It opens a development conversation rather than closing one down. 

The Esendia 4 Career Stages Framework (Sustain, Support, Stretch, and Shift) is built around this principle. Instead of asking "where does this person sit on a grid?", it asks "what does this person need right now, and where are they headed?" The difference is not cosmetic. It changes what the conversation is about, what data is collected, and what development actually follows.

What a Two-Way Process Actually Looks Like 

The fundamental problem with the 9 Box Grid is that it is a one-way assessment. The manager evaluates. The employee is evaluated. The two never meet in the same conversation, because the whole point of the calibration session is to protect the rating from employee interference. 

A career-stage approach inverts this. Managers and employees both prepare for the conversation using structured reflection prompts. The employee brings their own assessment of where they are, what they want, and what they feel they need to develop. The manager brings theirs. The talent conversation becomes a genuine exchange rather than a verdict delivered, or more often withheld. 

This matters for data quality as much as it matters for engagement. When the employee's own career aspirations are part of the assessment, the picture of readiness is far more accurate. You know not just whether someone looks capable of a larger role, but whether they actually want one, what development they believe would help them get there, and what might cause them to look elsewhere if the organisation does not respond. 

That is the talent intelligence that succession planning actually needs. And it is entirely absent from any process that treats the assessment as something to be done to employees rather than with them.

The 9 Box Grid Engagement Cost Nobody Is Measuring

Organisations track the cost of external hiring. They track attrition rates and time-to-fill for open roles. What very few organisations track is the cost of the talent that leaves before it leaves, the disengagement that accumulates during months of talent review cycles in which the employee had no voice, received no development, and was given no clarity about their future. 

Research consistently shows that employees who feel their development is actively managed are more likely to stay and perform at a higher level. Employees who feel invisible in the process, who sense that decisions are being made about them in rooms they will never enter, disengage in ways that are hard to see until someone hands in their notice. 

The 9 Box Grid, by design, creates invisible employees. The confidentiality is not a bug in the system. It is built into the architecture of a process that was never designed to include the employee in the first place.

The Question Worth Asking 

If your talent review process produces a set of ratings that you cannot share with the people they describe, it is worth asking what exactly that process is for. 

It is not building your employees' capability, because no development is linked to it. Their engagement is not being built either, given they are excluded from it. And it is not even producing accurate data, because the most important input, what the employee actually wants and where they see themselves going, is never collected. 

What it is producing is a snapshot of manager opinion, calibrated through organisational politics, kept confidential to avoid a problem that a better process would not create in the first place. 

There is a different way to approach this. Start with the employee's career stage and aspirations. Use structured, forward-looking conversations to generate data that is genuinely useful. Connect every talent assessment directly to development activity, so that the output of the process is not a rating sitting in a spreadsheet, but a clear plan that the employee can see, own, and act on. 

The organisations building talent pipelines that hold up under pressure, through restructures, through rapid growth, through leadership transitions, are not the ones with the most sophisticated rating frameworks. They are the ones whose employees know where they stand, know what comes next, and feel seen enough to stay.
