The blind performance review: can independent assessments make appraisals fairer?

Imagine being asked to rate your own performance after you've already seen what your manager thinks of you.

Would their assessment influence yours?

What if you thought you'd exceeded expectations, but your manager had already selected "meets expectations"?

Would you change your answer?

Would you become defensive?

Or would you spend more time preparing to justify your rating than reflecting on your actual performance?

Now reverse the situation.

A manager opens an employee's self-assessment before completing their own review.

The employee has rated themselves exceptionally highly.

Could that influence the manager's judgement?

These scenarios highlight a challenge in performance management: our assessments can be influenced by information we encounter before making an independent judgement.

One possible response is the blind performance review.

But what does that actually mean, and can it improve appraisal discussions?

What is a blind performance review?

A blind performance review is an appraisal approach in which employees and managers complete their assessments independently before seeing each other's responses.

The purpose is to encourage each person to consider the evidence and form their own judgement before comparing perspectives.

For example:

1. The employee completes their self-assessment.
2. The manager completes their assessment.
3. Both assessments remain concealed while the other party is completing theirs.
4. The assessments are brought together for the review discussion.
5. Differences are explored using relevant evidence.
6. Agreed development actions are recorded.

This is different from an anonymous appraisal.

Both parties know who is involved.

The temporary separation concerns the assessments, not the identities of the participants.

The problem with appraisal anchoring

Anchoring is a cognitive bias in which an initial piece of information can influence later judgements.

In an appraisal, an early rating may become a reference point.

For example, a manager sees that an employee has rated themselves five out of five.

Even if the manager has different evidence, that rating may influence their assessment or the discussion.

Alternatively, an employee who sees a low managerial rating before completing their self-assessment may become discouraged or focus on defending themselves.

This doesn't mean every person will be influenced in the same way.

Nor does it mean independent assessments eliminate bias.

But separating initial judgements can help reduce one potential source of influence.

Why traditional appraisals can feel unfair

Performance reviews often involve complex judgements.

Managers may need to assess:

• Achievement of objectives.
• Quality of work.
• Professional behaviours.
• Collaboration.
• Development.
• Contribution to wider organisational priorities.

These areas are not always easy to measure.

Several common problems can affect the process.

Recency bias

Recent events receive disproportionate attention compared with performance across the full review period.

Halo effect

A positive impression in one area influences assessments of unrelated areas.

Horn effect

A negative impression in one area influences wider judgements.

Inconsistent standards

Different managers interpret rating descriptions differently.

Insufficient evidence

Ratings are based on general impressions rather than documented examples.

Blind assessments don't resolve all these problems.

They are one component of a more structured appraisal process.

How independent assessments can improve the conversation

Consider an employee and manager assessing the same objective.

Objective: Improve communication with internal stakeholders.

The employee rates themselves as exceeding expectations.

The manager rates the employee as meeting expectations.

If both assessments were completed independently, the discussion can begin by exploring the evidence behind each perspective.

The employee might highlight positive feedback from stakeholders.

The manager might identify an area where communication could have been more consistent.

The aim should not be to establish which person "wins".

It should be to understand the evidence, identify any differences in expectations and agree a fair conclusion.

A practical appraisal example

Review area	Employee perspective	Manager perspective	Discussion
Project delivery	Exceeded expectations	Met expectations	Review delivery outcomes and agreed criteria
Communication	Met expectations	Met expectations	Recognise consistent performance
Leadership development	Exceeded expectations	Developing	Explore evidence and expectations
Professional learning	Strong progress	Strong progress	Agree next development opportunity

Differences can be useful.

They may reveal unclear expectations, overlooked achievements or development needs.

But they should be explored respectfully and with appropriate evidence.

Why concealment should be temporary

Blind assessments are not intended to create secrecy.

Employees should understand:

• The assessment criteria.
• The rating scale.
• The review process.
• When assessments will be shared.
• How disagreements will be handled.
• Who can access the information.

The purpose is to preserve independent initial judgements, not to surprise employees with undisclosed criticism.

In particular, serious performance concerns should be raised through appropriate ongoing management processes rather than saved for an appraisal meeting.

How to design a fairer performance review

1. Define clear criteria

Employees and managers should understand what each assessment category means.

For example, "exceeds expectations" should have a reasonably consistent interpretation.

2. Use evidence across the review period

Consider objectives, work outcomes, relevant feedback and development records.

Avoid relying entirely on the most recent few weeks.

3. Complete assessments independently

Where appropriate, prevent one party's initial ratings from influencing the other's assessment.

4. Compare perspectives constructively

Explore differences using examples and agreed expectations.

5. Agree meaningful development actions

Focus on what the employee should continue, improve or develop.

6. Follow through

Development objectives should remain visible after the appraisal.

Otherwise, the process risks becoming another isolated annual exercise.

From appraisal findings to SMART objectives

A useful appraisal should lead to clear next steps.

SMART objectives are commonly described as:

• Specific.
• Measurable.
• Achievable.
• Relevant.
• Time-bound.

For example:

Vague objective: Improve leadership skills.

More specific objective: Lead two agreed team improvement meetings over the next three months, gather feedback and review the experience with the line manager.

Not every professional development goal needs to be reduced to a numerical target.

But employees should understand what they are working towards and how progress will be reviewed.

How WorkplaceHero approaches independent appraisals

WorkplaceHero's Passport for Teams supports separate employee and manager assessments.

Initial responses remain concealed until both assessments have been completed, supporting independent reflection before comparison.

The resulting discussion can inform agreed development objectives and the employee's Growth Plan.

This connects the formal appraisal to continuing professional development.

It also reinforces an important principle:

An appraisal should be a conversation informed by evidence, not a contest between two ratings.

What blind appraisals cannot fix

Independent assessments are useful, but they are not a complete solution to appraisal bias.

They cannot compensate for:

• Unclear expectations.
• Discriminatory practices.
• Inadequate management training.
• Poorly designed rating scales.
• Insufficient performance evidence.
• Inconsistent organisational standards.
• Lack of appropriate challenge or oversight.

Organisations should consider manager training, calibration, employee feedback and fair review procedures alongside independent assessments.

Frequently asked questions

What is a blind appraisal?

A process in which employee and manager assessments are completed independently before their initial responses are shared.

Do blind reviews eliminate bias?

No. They may help reduce some forms of influence, such as anchoring, but other biases and process weaknesses can remain.

Should employees see their manager's assessment?

Employees should have an appropriate opportunity to understand and discuss their assessment. Blind review processes temporarily conceal initial responses rather than permanently withholding them.

What happens when employee and manager ratings differ?

The difference should be explored using relevant evidence, clear criteria and constructive discussion.

Can blind reviews improve performance management?

They can support independent reflection, but effectiveness depends on the wider quality of the appraisal process.

Final thoughts: fairness begins before the meeting

A fair appraisal isn't simply about reaching agreement.

It's about using relevant evidence, applying clear standards and allowing both parties to contribute meaningfully.

Independent assessments can help preserve different perspectives before the conversation begins.

But the real value comes from what happens next.

Listening.

Understanding.

Challenging assumptions.

And agreeing meaningful development.

The best appraisal isn't the one where everyone starts with the same rating. It's the one where everyone has a fair opportunity to explain their perspective.
