This article is from the Recreational Figure Skating FAQ, by Karen Bryden with numerous contributions by others.
United States Figure Skating Association (USFSA) is the organization
with the tie-in to the International Skating Union (ISU), and the one
which sponsors the U.S. National Championships (and all the
competitions leading up to it) that result in the world team being
picked. USFSA runs a "learn to skate" program, schedules tests and
Skate Canada (formerly known as Canadian Figure Skating Association or
CFSA) runs programs which are roughly parallel to the USFSA program.
They start with Canskate, which is a learn-to-skate program, followed
by Canfigureskate (basically a children's' program) and "test stream".
Other ISU member countries have got their own National skating
associations with similar aims as the USFSA and Skate Canada and their
own skating programs, such as DEU (Deutsche Eislauf-Union) in Germany,
NISA (National Ice Skating Association) in UK, FFSG (Federation
Francaise des Sports de Glace) in France, etc.
ISI (Ice Skating Institute) was formed out of a real need felt by
recreational skaters for a testing, instructional, and competitive
structure that did not devalue the "run of the mill" skater. It does
not only encourages participation in skating as a recreational sport,
but is also active in producing information and education material
directed to ice rink owners and operators and covering all aspects of
ice skating as a trade. Its program has been adopted by a large number
of ice facilities across the USA. ISI also has an international branch
with member rinks in 11 countries.
The ISI freestyle test requirements are listed in Appendix 2
