If she does NOT participate in any scrimmages or games she will not have to sit out any games. The rule is covered in the OHSAA By laws 4-7-2.
If she DOES PLAY in a scrimmage, which many schools will start having this coming week ( SOME schools are scrimmaging at indoor facilities ), she will have to sit for 13 games as the maximum number of games that can be schedule is 27.
Bottom line, if you want her to play at the new school, have her sit out this year.
Some people might say, let her play this year and sit for half next year.
Consider the following: Is she going to be a varsity starter as a freshman? If your daughter is pretty good, does her new school have someone at her position where she may NOT get a chance to start at the new school? If that is the case, does your daughter have a second position that she could play at the new school? You really need some info on the new school to help decide your decision for this year.
Problem is, you don't have a lot of time to make the decision UNLESS your current team has no access to indoor facilities as most teams won't get outside for at least the next two weeks.
