The new 2015 USEF/USDF dressage tests go into effect on December 1, 2014. The new tests are for all levels. They should be available in early November and the USEF will likely have a link to the new tests on their webpage, just as they have the current ones linked.
I will post more information as it becomes available! Don't forget to renew your memberships for the 2015 competition year! Membership expires November 30, 2014.
