Re: Underqualified Sensei
Aikikai rank can be verified by simply e-mailing them. I have done so in the past.
Instructor certification is generally left up to the organization. Some do so formally although it does not guarantee someone is good at teaching. Everyone has their own learning style and finding yours and the person who can help you explore it is the biggest challenge. Low ranking instructors can be good instructors and lousy technicians. THe same as high ranking instructors can be good technicians and lousy instructors.
