IQCs are frequently held at Osaka and Yokosuka in Japan by an ASA international instructor evaluator Yoh Aoki.

ASA Sailing Instructor clinics test existing skills and knowledge while teaching a structured curriculum and proven presentation techniques. ASA certified sailing instructors have proven they measure up to a national standard which is used by more than 90% of the commercial sailing schools in the country. Take the challenge and attend an ASA Instructor Qualification Clinic (IQC).
