What’s the difference between a AFF certification and an “A License”?

AFF certification states that you can jump solo, safely. A USPA “A License” states that you have achieved certain level of proficiency or expertise. To receive an A License you have to have made 25 skydives, review certain items with an instructor, and demonstrate certain skills. While many skydiving companies will allow you to jump after completing AFF certification at a different company, some will make you jump with an instructor to demonstrate your skill level first. However, an A License will allow you to jump pretty much anywhere in the world. An A License also allows you to go 60 days between jumps instead of 30 days.
