The path to becoming an instructor or professional skydiver might be considered similar to vocational training, taking several months, or even years depending on the rating. First, there is solo certification. This is AFF training and requires a minimum 7 jumps. The certification allows you to jump without the supervision of an instructor. Second, there are 4 levels of licensing- the A (25 jumps), B (100 jumps), C (200 jumps), and D (500 jumps). Each has its own set of additional requirements. At 100 jumps and a B license you can take a course to achieve a USPA Coach rating. At 200 jumps you are eligible to be an aerial photographer. At 6 hours of freefall (approximately 350 to 400 jumps) you are eligible to take the Accelerated Freefall Instructor rating course. At 500 jumps, a D license, and 3 years since your first jump, you are eligible to take the Tandem Instructor Certification Course.
The majority of the time spend during this process is self-directed. There are no formal courses for the entire process.
