Also, the tests must still be “adjacent” to one another. For instance, A Para riding Para II tests (walk-trot) cannot ride the same horse in the same show that an able-bodied rider uses for Third Level. If the able-bodied rider is riding Training Level, it would be OK, I believe.
Check with your TD or show secretary to be sure. Also, the Para Equestrian website should be of help. (USPEA)
I loaned my Third Level horse to my PARA student for a show last year, but I rode my Third Level tests on the first and third days, she rode on the middle day. All three days were separate “shows”, so there was no conflict. She chose to ride Training Level tests, not PARA tests, but the same rule applies, of course.
Your student may need her USEF and/or FEI PARA card to compete. These cards verify the level of disability and the adaptive devices allowed. Again, if your rider has not gone through this process yet, ask your show secretary or TD. If it’s a local or schooling show, inform the show management and ask all the questions you need. You should be fine.
Everyone has been VERY supportive of my PARA student and they bend over backwards to support and encourage her!
