Good Tilly! :)
I've noticed quite a few clubs teach a level above - at least where I used to live - i.e. the Puppy Foundation class would actually be bronze level including the requirements for Puppy Foundation, and then a different club did Bronze and Silver in the same class. One club did the Puppy Foundation final assessment and the bronze test afterwards on the same night. Another did Bronze tests followed by Silver test straight after for any dogs which were ready. My own lad did his bronze and Silver tests one after the other on the same night, and passed both!
TBH I personally don't see the rush, I would rather they took longer between tests as a dogs' temperament can change a lot in its first year. Mine may have got Puppy, Bronze & Silver before 12mths of age, but as the hormones took hold he regressed a lot and at now, 5 years old would struggle to pass Bronze in a class situation.
