A colleague and I did the Cross-country course designer program together this year - we started with the training program this February 2024 at Fresno, California, on the official path. It was a great course and I learned a lot. The attendees were a mix of new applicants and those doing their updating (you must attend one every 3 years) - Cross-country designers, TDs, and Judges.
The best advice I can give you is if you want to attend in an official capacity (I didn’t know you can audit), start your checklist NOW. There are requirements including background checks that take a bit of time, and it was very stressful trying to do this all in a short time-span!
There is an “officials’ grant” available to apply for which could help defray costs of attending the course - definitely apply.
Nancy Knight is the Senior Director of Education and she is very helpful and responsive - if you haven’t already, send her an email and she’ll put you on the list for getting information etc. And she will assist with making sure you are getting all the right requirements checked off!
My friend and I both did all our apprenticing and attended the final exam in Georgia in October, which we both passed. It was an intense but very satisfying year!
