While I support you exploring all of your options, have you considered diet? My son's teacher wanted him to be tested for ADD last year and I held off and decided to work on his diet first. I got him on some good whole food vitamins and cut down on his sugars and white carbs.
There's been some amazing studies on supplements and ADD/ADHD

Pycnogenol has been shown to balance stress hormones and can be found in Isotonix OPC-3, an isotonic supplement. You can get a 30 serving size bottle for $28.95 or 90 servings for $67.50 Here is the website where we order ours from: www.marketamerica.com/C.
After changing my son's diet and supplements, his teacher said his behavior has improved significantly and hasn't mentioned another word about getting him tested. Best of luck to you!
