There are a number of ways to find a qualified ADHD assessment centre. The best place to start is by talking to your doctor or child's pediatrician. They may be able to refer you to a specialist or testing centre in your area. You can also search online for ADHD assessment centres or contact your local mental health association. Once you've found a few potential centres, it's important to do your research to make sure they are reputable and have experience assessing for ADHD.

You can read reviews online, check with the Better Business Bureau, or ask for references from people you trust. When you've narrowed down your options, contact the centre to ask about their process and fees. Once you've found a qualified assessment centre, they will be able to help you determine if your child has ADHD and develop a treatment plan.
