There will be five grades for experienced greyhounds, designated by the letters AA, A, BB, B, and C.
Grade AA shall be the highest classification and Grade C shall be the lowest.
Further, Grades M and J shall be used for inexperienced greyhounds with Grade M referring to Maiden classification and Grade J referring to Juvenile classification. Grade M races are sometimes run as non-betting races.
Grade S shall be used for greyhounds entered in stakes races and special races.
Grade T shall be used for greyhounds used in mixed grade races.
How Greyhounds are Raised in Grade
The winner of any graded race shall be advanced one grade until it reaches Grade AA. Greyhounds winning Grade M shall be placed in Grade J. Greyhounds winning in Grade J shall be placed in Grade B.
How Greyhounds are Lowered in Grade
Greyhounds racing in Grades AA, A, BB, or B and finishing farther back than third three consecutive times, or failing to earn more than one third in four consecutive starts while in the same grade, shall be lowered one grade. The following criterion also apply in lowering a greyhound a grade:
a) Greyhounds having advanced to Grade AA from Grade A shall be lowered back into Grade A if they finish farther back than fourth in their first two starts in Grade AA. After finishing as far up as fourth in Grade AA, they will be lowered by the regular procedure. This applies each time a greyhound advances to Grade AA from Grade A, even though such greyhound may have, at some earlier time, won in Grade A.
b) If, in the opinion of the Racing Secretary, a greyhound has been misgraded, the greyhound may be lowered one grade at a time until such greyhound has finished as far up as fourth.
c) If having never run better than fifth a greyhound runs sixth, seventh, or eighth in his first two starts at fifteen to one or more, the greyhound drops a grade. This rule only applies to the first two starts in Grades AA, A, BB, or B.
d) Greyhounds finishing farther back than fourth four consecutive times in Grade J, shall be lowered to Grade C.
Grade C, Maidens and Juveniles
Greyhounds shall become "overage" when their age reaches the first day of it's 25th month.
Greyhounds, who are not "overage" dropping from Grade B will once again enter Grade J. This applies to those Greyhounds that previously won a Grade J race at Lincoln. Once a greyhound has won a Grade B race, this rule shall no longer apply.
Grade J Greyhounds that had previously won Grade J, shall enter Grade C when they become "overage."
Grade J Greyhounds which become "overage," have never won a Grade J race, and have had 25 starts or more must leave Grade J. The Racing Secretary shall enter these greyhounds in either Grade B or Grade C depending on the greyhound's past performance lines.
Grade M greyhounds which become "overage" must leave Grade M. The Racing Secretary shall enter these greyhounds in either Grade J or Grade C depending on the greyhound's past performance lines.
Greyhounds will be dropped from further entry after finishing farther back than fourth four consecutive times while racing in Grade C. Maidens will be allowed to finish farther back than fourth five consecutive times while in Grade M races. Maidens which become "overage" and enter Grade C will be dropped from further entry after finishing farther back than fourth five consecutive times in a combination of Grade M and Grade C races. Lines showing on Grade C and Grade M greyhounds which fell, met interference, were impeded, or raced in Grade T races will not count towards grading off.
Races Compiled by Draw
Greyhounds for the different races will be drawn from their respective grades, the Racing Secretary reserving the right to either draw or classify Grades AA or M or races longer than 5/16th mile.
Distance and Stakes Races
a) Greyhounds of different grades may be used in races longer than 5/16th mile. The winner of these races shall advance one grade, the same as if the greyhound had won its own grade. Non-winners shall be given credit for their start in the usual manner. Mixed grade races shall be designated as Grade T in the program. Stake races and special races shall be designated as Grade S in the program.
b) Stake races may be composed of mixed grades with the greyhounds being raised or lowered as if they were running in their own grade.
The Fall Rule
Greyhounds falling in an Official Race must school to the satisfaction of the judges. To fulfill this requirement, they will be allowed to hand school from finish line to finish line before the Judges and the Track Veterinarian.
Greyhounds that fall in an Official Race and hand school to the Judges satisfaction will have the designation "Judged OK" and the date which they had hand schooled in replace of the Chart Writer's "Fell" comment for that particular race.
Should a greyhound not fall but the Judges want the greyhound to hand school for another reason, an asterisk (*) will appear at the end of the Chart Writer's comment to show that the greyhound hand schooled to the Judges satisfaction after that particular race.
