There's already been several posts saying that 100% attendance awards aren't fair on kids with health conditions and disabilities as they wouldn't be able to win
@Florenz, I'm going to assume you just don't have much experience of childhood disabilities rather than trying to be offensive. But FYI there is a whole range of health conditions and disabilities which would mean you were considered disabled but wouldn't prevent you doing some physical activities, or which might mean you could occasionally do such activities but not all the time.
DS for example has a (physical) condition which means he is considered disabled, but he works as a sports coach and PT and his main hobby is doing cross-fit. His students wouldn't know about his disability because on the bad days, he doesn't do them.
