Size is irrelevant!
How big, how small, really is of no importance. For the OU Cisco ASC, we are happy if you are teaching single digit numbers - equally we are happy if you offer Netacad to over 1000 students each year. It isn't a competition. We attempt to treat everyone with equality irrespective of size.
There is a myth circulating regarding numbers - where we have encountered some Cisco Academies concerned that we will charge (or Cisco) when a limit is reached. This is not the case. Every course can be delivered to as many students as you can muster FOR FREE. You do have to meet some expectations (read on) from both Cisco and the OU Cisco ASC, however these are also not unreasonable.
