text: Iowa has separate governing associations for boys' and girls' sports, including the Iowa High School Athletic Association and the Iowa Girls High School Athletic Union. Only the Iowa High School Athletic Association is a full member of the NFHS; the girls' governing body is an affiliate member.
  The provincial associations of Canada are affiliate members of the NFHS.
  The NFHS publishes rules books for each sport or activity, and most states adopt those rules wholly for state high school competition including the non member private school associations.
  The NFHS offered an online Coach Education Program in January 2007. It released a course, Fundamentals of Coaching. The NFHS has announced that it will offer a National Coach Certification in September 2009.  This will enable to coaches to become a Level 1 - Accredited Interscholastic Coach issued by the NFHS.
