Thank you for your question and welcome to ADHDCentral. Schools do not evaluate for ADHD as this is considered a medical condition, not a learning problem. You should ask your doctor for a referral to a psychologist or psychiatrist in your area that specializes or has experience working with children with ADHD and other mental illnesses.
I have included some links to information on the site that might be of help to you:
Evaluating Children: What to Expect
The People You Meet: Medical Personnel
Rating Scales for ADHD
Creating a Treatment Plan
Find a Healthcare Provider
Advocacy When Dealing with Medical Providers
I hope this information helps you. Please let me know how everything works out.
