At EASE, as of January 2014, we are teaching the PADI IDC with the new open water course curriculum material.
PADI Instructor Examiners have assignments that reflect both the classic and revised edition of the PADI Open Water Diver course. The only change at this point is that the revised Prescriptive Lesson Guides differ from those in the classic version.
As with the PADI Divemaster course revision, both assignment types (classic and revised) are available at the examination and candidates simply choose the assignment that applies. Examiners can also assist if candidates have questions.
To reiterate, outside of knowledge development, no new skills have been added to the Instructor Examination assignments. The skills from the revised PADI Open Water Diver course will be introduced in the Instructor Examination later this year.
The IDC crewpack include the revised material.
