While the IEA does not currently have its own lettering program, some of our partner organizations do.
Here are links to a couple of the lettering programs offered:
USEF - https://www.usef.org/start-riding/youth-programs/lettering
NRHA - http://www.varsityreining.com/overview/
Separate membership in USEF or NRHA is one of the requirements of participation. IEA riding/showing experience may count toward achievements. Please contact the program sponsors for more information.
