Whilst standard briefings may sound like a good idea, the reason instructors have there own briefings is because they are made to THINK for themselves and to research topics in depth before constructing a brief. The end result being a more competent instructor IMHO.
As for Schools in BK, best you take advice of others by dropping in and having a chat to instructors, inspecting facilities etc. My students are very happy with our facilities and quality of instruction, so don't be guided by size alone (big or small). I love my job
