Coaches and Users are separate items but some coaches could still be users. Here are the definitions of what they are on Home Campus.
Users: Anyone that has a login account on Home Campus who can make some sort of adjustments (i.e. schedules, clearances etc). Each school can have as many or as few coaches as they would like. To learn more about Users Click Here.
Coaches: A coach that has been entered into your Home Campus account can have their information stored (contact information, certifications, expiration dates etc.). Make sure to assign them as the Varsity Head Coach for their sport so they will appear on the CIF directory.
