Traditionally, member's ranks are tracked on a board hung in the dojo. We have created a 'virtual' nafudakake to show each member's rank.
Aikido is more than 'just doing the moves'. As one progresses in rank, one should start to demonstrate knowledge and application of concepts such as maai, zanshin, and kuzushi.
Testing provide a platform for students to demonstrate their progression - and for instructors to determine gaps within the training curriculum.
