Are pre-employment personality tests legal?

The honest answer is that it depends on where you hire, and that anyone giving you a confident one-line answer for eleven countries is wrong somewhere. Here is what to ask instead.

Pre-employment personality tests are lawful in many places and constrained everywhere, and the constraints differ by country and often by state. This page is not legal advice and does not tell you what any law requires. It sets out what to ask a qualified adviser, and the process practices that tend to keep a hiring process defensible wherever you are.

This page is not legal advice

Employment law differs by country, by state, and sometimes by the size of your company. Whether a particular assessment is permissible where you hire, and under what conditions, is a question for a qualified employment lawyer in that jurisdiction. Nothing here characterises what any law requires, permits or prohibits.

That is a real limitation and worth stating plainly rather than hedging around. Pages that summarise employment law for eleven countries in nine hundred words are wrong somewhere, and you will not know which part.

What to ask a qualified adviser

These are the questions that actually determine whether an assessment can be part of your process. Take them to someone licensed where you hire.

In the United States: whether EEOC guidance applies to us at our size, and what record we would need to keep if a selection decision were challenged.
In the United States: how the ADA treats the specific instrument we are proposing to use, and where the boundary sits between a personality questionnaire and a medical assessment.
In Singapore: what the PDPA requires of us for consent, access, correction and deletion of assessment data, and how long we may keep it.
In any jurisdiction: what we must tell a candidate before they take an assessment, and what they are entitled to see afterwards.
In any jurisdiction: whether our answer changes if the assessment data is stored or viewed outside the country the candidate is in.
Whether any of this changes when we assess an existing employee rather than a candidate.

The last one surprises people. The relationship is different, the power balance is different, and the answer is often different too.

Is a personality questionnaire a medical assessment?

This is the distinction most worth raising early, because it is the one where an instrument's design matters rather than your intentions. Some instruments are built to describe how someone tends to work. Others are built, or have been used, to identify clinical conditions. The two are not interchangeable and are not treated the same way.

We are not going to resolve that boundary for you — it depends on the instrument and on where you are. Raise it specifically, name the instrument, and get the answer in writing.

Practices that hold up regardless of jurisdiction

Legal advice is jurisdiction-specific. Good process mostly is not, and a defensible process is the same one that makes better decisions.

Assess against a role you defined in writing before you saw any candidates.
Run the same process for every candidate for that role. Divergence is where challenges land.
Use assessment as one input among several, never as the sole basis for rejecting someone.
Tell candidates what you are collecting, why, and what happens to it — before they take it.
Let candidates see their own results. If you would not be comfortable showing someone their profile, do not collect it.
Record the reason for each decision at the time you make it.
Keep the data for a stated period and then delete it, rather than keeping it indefinitely because deleting is effort.

Every item on that list is also just a better way to hire. That is not a coincidence — most of what makes a process legally defensible is that it was consistent and written down.

Where we stand on this

A personality profile describes tendencies. It does not measure ability, character or worth, and there is no good or bad end of any dimension we report. An employer reading one as a score has misunderstood what they are holding.

A candidate's profile is theirs. An organisation sees it only through an explicit grant that the candidate can revoke, and their individual answers never leave their phone. That is a design decision rather than a compliance feature, but it happens to make several of the questions above easier to answer.

How access, consent and revocation actually work here — Our approach to permissioned access

Can I require a candidate to take a personality test?

Whether you can require it, and what happens if someone declines, is a question for a qualified adviser where you hire. As a matter of practice, we would not build a process that rejects someone for declining, because a profile taken unwillingly is poor evidence anyway.

Do I have to tell candidates the results?

What you are obliged to disclose varies. What we would recommend regardless: let them see it. A process you would be uncomfortable explaining to the candidate is usually a process worth changing.

Can I use an assessment to reject someone outright?

Ask your adviser about your jurisdiction. Ours is a simpler position: no assessment we produce is a sufficient basis for a rejection on its own, and it is not built to be used that way.

How long can I keep candidate assessment data?

Retention periods are set by local law and sometimes by what you told the candidate. Decide a period, state it, and delete on schedule — indefinite retention is the default only because nobody chose otherwise.

Does any of this change for existing employees?

Often, yes. Assessing someone who already works for you is a different relationship with a different power balance, and both the legal position and the ethical one can differ. Raise it as a separate question rather than assuming the hiring answer carries over.
