When to use a skills test, and when not to

A good skills assessment is one of the fairest tools in hiring. It judges what someone can do rather than how well they interview or how their resume reads. A bad one wastes everyone's time and screens out good people for the wrong reasons. The difference is almost always in how you use it, not which test you buy.

Use a test when the skill is the job

Assessments earn their place when the role depends on a concrete, demonstrable skill: writing code, analysing data, drafting copy, handling a customer. If you can build a short task that looks like the real work, you will learn more in twenty minutes than in an hour of talking about it.

Skip it when it is a hoop

A test that has nothing to do with the day-to-day, or that mostly measures who has time to grind practice questions, is just friction. It will cost you good candidates who opt out, and tell you little about the ones who stay. If you cannot explain how a test maps to the role, do not run it.

Keep it fair and consenting

Tell candidates what the assessment is, why you are using it, and roughly how long it will take, before they start. Keep it proportionate to the stage: a short screen early, a deeper task later, never a multi-hour project for a first conversation.

Make reasonable adjustments available without making people ask awkwardly. A fair test is one a candidate would call fair even if they did not get the job.

• Explain the purpose and the time up front
• Match the depth to the stage in the process
• Offer adjustments as standard, not on request
• Pay for substantial work, or keep it short

Read the score, do not obey it

A score is one input, not a verdict. Use it to inform the human decision, not replace it. Look for the band a candidate falls in rather than treating a single point as meaningful, and always pair the result with what you learn in conversation. The test tells you what someone can do. Only a person can weigh that against everything else the role needs.
