The twelve seitei-gata are standardised for the tuition, promotion and propagation of iaido within the kendo federations. Although not all kendo dojo teach seitei iaido, the AJKF uses them as a standard for their exams and shiai. As a result, seitei iaido has become the most widely recognised form of iaido in Japan and the rest of the world.Zen Nippon Kendo Renmei Iai, English Version Manual 5th edition, published March 2014, by All Japan Kendo Federation, Tokyo, Japan.
