1) Use the map above to find your nearest FAA drone testing center
2) Follow the steps in this guide to get your FAA Tracking Number (FTN). This will take you no more than 10-15 minutes.
3) Use your FAA Tracking Number to create an account with PSI. This is the central testing company. You ultimately pay for and schedule your exam date directly through them. The cost should be right at $173, although some test centers are owned by PSI (test provider) directly and charge $109.
