Upon completion of ground school (for AFF, IAD and SL) and before the first jump, it is common practice and good teaching procedure for all students to be required to pass written, oral and practical tests.
Written tests are designed to have the student explain his knowledge and understanding. Oral tests should be used to develop decision-making ability. Practical tests are designed so the student can demonstrate reactions and skills.
Tests will not only assure the instructor that the student has learned but will also give the student confidence that he has learned how to safely make a skydive.
