Does the FAA always require a neuropsychological assessment battery for applicants with a history of ADD? I'm in the middle of a medical struggle with the FAA. I'm applying for a 3rd class medical certificate but was hit with a deferral letter due to a childhood ADD diagnosis. Currently the FAA is only asking for:

&quot;A personal statement regarding my ADD history and medication use.&quot;
&quot;All treatment records and evaluation from the physician who prescribed the ADD medications in the past.&quot;

My question is this - does the FAA require a neuropsychological battery test for all applicants with an ADD history, or is their requesting a testing battery contingent upon what I say in my personal statement and the included treatment records / evaluations?
My treatment records and physician evaluation conclude that I no longer have ADD symptoms. In addition, I've flown intensively with a United Airlines check airman (pilot responsible for evaluating the flight ability of other United Airline pilots) and he has written a letter stating he's seen no evidence of ADD and, in his professional opinion, I am qualified to pilot an airplane.
Do you think, after submitting this documents in my favor, I will be able to avoid undergoing the testing battery?
If you have ever in your life been diagnosed with any mental health condition, such as ADD/ADHD, then the FAA presumes you to be mentally defective until proven otherwise to their satisfaction, by their own experts at your expense. They do not care what your personal doctor says, or what other pilots say.
You will need to get evaluations from a HIMS Psychiatrist and/or HIMS Neuropsychologist, which will likely take you months to arrange since there are only a few in the entire country. Then you will need a HIMS AME to process the paperwork and send it to OKC, which will spend a few months reviewing it to make sure the file is complete. Then your file will be sent to DC, where it will sit on the Federal Air Surgeon’s desk for several more months before he reviews your file. If all goes well, he will issue a Special Issuance medical, conditional on renewing the above evaluations every 6 or 12 months until he is eventually convinced you are mentally stable enough for a regular medical certificate. That may take up to 10 years, depending on your exact condition.
If your AME is not a HIMS AME, they will have no idea how this process works or what paperwork is required, so switch now and save yourself months of wasted time and money.
