There are six grades of greyhounds indicated by A, B, C, D, J and M (Maiden). The winner of any race is advanced one grade until reaching A.

GRADE “J” FACTS
• When a greyhound  wins a Grade “M” race, it will advance to Grade “J”.
• When a greyhound  wins a Grade “J” race, it will advance to Grade “C”, and then to “B” and “A”.

GRADE OFF RULES
• Any greyhound  who fails to finish at least fourth in six consecutive official Grade “D” starts shall grade off.
* Some tracks’ grading systems differ from Ebro
