Please read over the rules carefully. Some classes at EHA shows may also be NCHJA C rated. EHA will follow NCHJA rules for classes that are rated by both organizations. EHA follows the USEF rules unless otherwise noted. Our rulebook serves to show how we differ from USEF, listing rules that are specific to EHA and it by no means contains every rule. If it is not covered in our rulebook, then we go by USEF rules. We recommend that you visit the USEF and obtain a current rulebook. If you have any questions regarding EHA rules, our senior steward, Bill Creighton, will answer them.
