This is probably a dumb question, but can anyone tell me what the AAA is in a horse pedigree?

No dumb questions here! 

AAA refers to a specific “letter grade” Speed Index rating of SI 90-95 within the “Speed Index” rating system.  The Speed Index is a system of rating the performance of racing Quarter Horses.   The (AQHA) American Quarter Horse Association originally used the  letter grade system which started with the letter D, then C, B, A, AA, AAA, AAA+, and finely AAAT.  Then in 1969 it was decided that the letter grade system was too cumbersome and the Speed Index (SI), which used a strictly numeric system, was introduced.  The numeric (SI) is the current system used today.

The “letter grade” rating worked as follows:

A                          = a Speed Index (SI) of 70-79
AA                        = a Speed Index (SI) of 80-89
AAA                      = a Speed Index (SI) of 90-95
AAA+                    = a Speed Index (SI) of 95-100
AAAT (TOP AAA)    = a Speed Index (SI) of 100+

Hope this helps.
