All Instructor training begins with the Instructor Development Course, the PADI instructor training process is a two-fold process. The first part is the Instructor Development Course (IDC). In this portion, you will learn the PADI educational system and how to use the system. This is where you will build the foundation of being a good instructor. The IDC is made up of the Assistant Instructor program and the Open Water Scuba Instructor Program. If you are not sure if you want to become a PADI Instructor, you can do just the Assistant Instructor. With this certification you are a integral part of the instruction teach.
