I had to do additional testing for previous ADHD medication in August. I had to schedule an appointment with an FAA-approved neuropsychologist, and it went something like this:
Show up at 8 am and meet with the neuropsych for 15-30 mins to establish my social history, medical history, psychiatric and substance abuse history, and behavioral observations. These are like a first meeting/ get-to-know-you with a regular psychiatrist. After the meeting, one of his employees handled my testing for the rest of the day.
The tests were as follows:
Intellectual Abilities
-Verbal Comprehension
-Perceptual Reasoning
-Working Memory
-Processing Speed
Language
-Verbal Fluency
-Boston Naming Test
-WMS-IV
-R-AVLT
Sustained Attention/Vigilance
-PASAT
-DVT
-Conners Continuous Performance Test - 3rd
Executive Functioning
-Halstead Category Test
-Trail Making Test
-Stroop Test
-Rey Complex Figure
Fine Motor
-Motor Testing
-Manual Finger Tapping L/R
-Grooved Pegboard L/R
Visual Perception
-Judgement of Line Orientation
Symptom Validity
-MSVT
Psychiatric/Personality/Behavioral/Emotional Functioning
-MMPI 2 (again, but handwritten.)
CogScreen - Aeromedical Edition
A month or two later I got my results interpretation and a summary/recommendation. It was a pain and expensive ($2800 out of pocket), but worth it if I get the job. I was at the office from roughly 8:00-2:00 with an hour break for lunch. It was honestly kind of fun at times and genuinely stressful at others. It reminded me of an extended ATSA, and I assume my experience is somewhat indicative of the job itself.
EDIT for background: I took Adderrall in grade school for two years and then for one month ~10 years ago after graduating high school. I was never officially diagnosed with ADHD.
