In Ohio Ejection carries 2 game suspension, but in a contradiction, a coach ejected in a JV game IS allowed back in the gym for the Varsity game. I'm not sure if the suspension is only after the paperwork required by the state is filed by the ejecting referee or if the school is required to suspend immediately.
In 4 years, I've only had to do the paperwork once and it was for a player. I later found out that she received a
2 week 
in school suspension due to the incident occurring while she was already on probation for other in-school incidents. But the 4=part form we use for ejections has two that go to the school (AD & principal). Some schools may wait for the paperwork to enforce the penalty.
