HOW THE ASSESSMENT WORKS
How an online autism and ADHD assessment works in Washington
An autism and ADHD assessment is a structured evaluation that tells you whether autism, ADHD, both or something else best explains your experience, from childhood to now. It is done by Dr. Kiesa Kelly, a licensed psychologist based in Tennessee and authorized to see clients in Washington State by telehealth.
You start with validated questionnaires in our app, then a clinical interview and standardized diagnostic interviews such as the DIVA-5 for ADHD and the MIGDAS-2 for autism. Because the two conditions often overlap, they are weighed together rather than one at a time. A feedback session walks you through your results and what to do next.

FREQUENTLY ASKED QUESTIONS
Common questions from Washington State
Who can diagnose ADHD or autism in Washington State?
A licensed psychologist is one of the professionals who can. Dr. Kelly is based in Tennessee and authorized to see clients in Washington by telehealth, as long as you are in the state during each session.
How much does an adult autism or ADHD assessment cost?

Will my results work for college or workplace accommodations?
Your school or employer decides, so we can't promise approval. Many ask for a recent evaluation, a DSM-5 or ICD diagnosis and how it affects you day to day. Cognitive testing is an optional add-on. Check what they ask for first; we'll talk through your options.
