I usually put a Calendar of Events (found on this website) into student folders. Studio Policy (also found on this website) is usually given to parents/sponsors directly.
All unneeded prior-year posts (mainly outdated calendars and policies) have been hidden to keep things tidy. This site has been a great studio resource since 2011! (but we don't really need to know when the 2011 recital was coming up hahaha)
