At this point, all gradings stop.  If a karateka wishes to proceed beyond "Yondan" and have no licence, they must go back and pass Jun-Shidoin and Shidoin before attempting Shihan.  Since one must wait 3 years after Yondan to test for Shihan, they can challange the Jun-Shidoin and Shidoin during those three years. (Article 10 Canadian Chito-ryu Karate Do Instructors Manual.)
