What is a Qb Test?
The QB test is a diagnostic screening tool which provides objective information to aid the assessment of ADD/ADHD. The test uses age and gender matched comparisons to assess a child’s ability to concentrate, their movement and impulsivity. The Qb Test is an essential part of the ADHD pathway and the results are used in conjunction with other ADD/ADHD assessment tools to aid clinical judgement.
We are welcoming and friendly.
You will be welcomed on arrival by our Qb screener who will:
- check all your personal details are correct
- explain the test directions
- discuss why your parent/carer is requested to leave the room to aid your concentration
- watch a test instruction video
- complete practice tests to make you feel more confident
- you can ask questions prior to the test starting
- when you are ready the Qb screener will start the test
- our screener is with you to offer support if required
How does the test work?

The test will last 15/20mins dependent on your age. During the Qb Test you will be asked to:
- sit in front of a computer screen
- a soft flexible head band will be placed around your head with a reflective ball attached to
measure your movement during the test - you will hold the responder button in one of your hands
- you will click in response to certain shapes you see on the screen
- the test will automatically end after the required time
Frequently asked questions
Why do I have to have a Qb test?
The Qb results can help find out why you may be having difficulties in concentrating, feeling fidgety or having too much energy at night. Some of these feelings may be more noticeable in school. The results of the Qb can help determine the type of support you may need in the future
to help you feel more confident.
Does the camera film me?
The camera only films the movement of the infra-red marker attached to the headband. The only information the camera captures is how much the marker has moved during the test. Please don’t wear anything sparkly or with a reflective strip as this will interfere with the test equipment.
What if I get it wrong?
You can’t get it wrong. The Qb Test is about tracking how you respond and will help gather valuable information to help support you in the future. It is not a pass or fail test. Remember you will also have the opportunity to ask questions at your appointment so do not worry if your question is not on our list. If after reading this leaflet you feel the Qb Test may not be suitable, an alternative assessment can be provided by our service. See the appointment letter for contact details.
