The FSKA grading requirements for these two ranks factor in the karate-ka's age and previous experience. For those students under the age of 55 they are required to do the entire kihon, kata, and kumite requirements currently listed under the Yondan exam.
For those students over the age of 55 they may if they wish do the entire kihon portion of the Yondan exam. However, only the katas are required to be performed to the satisfaction of the examiner. Since, after decades of hard training many students above the age of 55 have sustained numerous injuries, that may limit their physical abilities. As well, these very senior students are usually very well known to the examiner from classes, courses, and their previous examinations.
