GOHJA On-Line

GOHJA Rule Book, Rule 3.4:
"Prior to showing in any division restricted to ponies, the pony's height measurement must be on file with GOHJA.  Ponies may be measured by a Show Steward at any GOHJA sanctioned show or the owner/representative may present the pony's USEF Pony Measurement Card for review by any Steward.  Ponies must be re-measured each show year until the age of six, at which time they are permanently added to the GOHJA Pony Measurement List.  Proof of age is also required for any pony being measured.  Acceptable proof of age includes a statement of age from a veterinarian or age listed on a breed registration certificate.
The GOHJA Pony Measurement List will be maintained by the Head of the Stewards Committee and will be published to the general membership at least annually."
