All the Standards have been updated and go into effect on 1/1/09. Below are the revised prep guides, new standards and a side by side chart of the differences between the 2007 and 2009 standards at each level.
If you have already completed your prep guide for your next rating you can look up the differences and indicate any new information on a separate page. For example, beginning in January you need to bring a stall chart for your D1-D2 test.
Turnout Attire for D1-D2 is described in each standard and is also written in the prep guide. C1-C2 are formal or informal and Attire page from the Horse Management Rulebook is under the C1-C2 information.
