How to choose a psychological testing practice
- Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
- Make sure psychological, ADHD and learning evaluations is a regular part of their work, and ask what approach they use and why.
- Ask whether the report will meet the purpose you need it for (school accommodations, a testing agency or your physician).
- Ask about fees, insurance and the cancellation policy before the first session. In the US, if you are uninsured or paying yourself, you can ask for a good faith estimate of expected charges.
- Check practical fit: in-person or online sessions, evening times, and how soon they have an opening.
- After a few sessions, ask yourself whether you feel heard. Changing to a different provider is common and fine.

Yes, if they are within 40 mi of the Mercerville city center, our service radius for psychological testing practices. Each listing shows where the practice is based and how far away it is. Proximity is 15% of the RP Score, so a nearby practice gets a small edge.

Schools and testing agencies may have their own requirements for a report, so ask what the evaluation includes before you book.
Can I see a psychological testing practice online?
Often, yes. Licensing generally follows where you are during the session, so the provider needs to be licensed or authorized there.

In Canada, ask whether the provider is registered in your province.
What if I need help right now?
