How to prepare for your ADHD assessment

You don’t need to study for an attention test — there’s nothing to revise and no “right” answer to memorize. But a little setup makes the objective results cleaner and helps you give the intake the accurate history it needs. Here’s what actually helps.

Pick the right moment

• Choose a time you’re normally alert — not right after a heavy meal or at the very end of an exhausting day.
• Find a quiet spot where you won’t be interrupted for about 15 minutes.
• Silence notifications and put other screens away, so the test measures your attention, not your phone’s pull on it.

Be honest on the intake

The DSM-5 intake asks about symptoms, when they started, and where they show up. It’s tempting to downplay the messy parts — don’t. The intake is only as useful as it is honest, and the clinician reading it isn’t there to judge you; they’re there to understand the pattern.

Think about your history beforehand

ADHD is defined partly by early onset, so it helps to recall what you were like as a kid: report cards that said “not living up to potential,” trouble finishing things, daydreaming, restlessness. If you’re assessing your child, jot down specific examples from home and school before you start.

A note on medication and substances

Caffeine, stimulant medication, and poor sleep can all shift how attention performs on a given day. You don’t need to change anything on your own — but if you already take medication for attention, mention it in the intake so the clinician can interpret your results in context.

Then just take it

Once you start the test, respond as instructed and let it run. You can’t “fail,” and trying to concentrate hard is completely fine — sustained effort on a dull task is exactly what’s being measured. A licensed clinician interprets the whole picture afterward, so no single moment makes or breaks your result.
