Cleveland County School District complaint: Cheerleader unfairness

My daughter has been a cheerleader for two years and now she has one D for the semester and now they are saying she can’t tryout this year. But school handbook says for eligibility you must have a 1.8 gpa by end of spring semester and this was fall semester they are going by. There is a cheer constitution and it states otherwise , it’s says student must have “C” or above in all four classes but the constitution and handbook doesn’t align with each other so that’s a conflict in itself. It went I. Front of board , they are gonna change it next year so they agree with each other but for now they said there was nothing I could do. Also there is other sports at our school and students have Fs and more than one D and still get to participate. It’s not fair and it should all be treated equally. Please help or tell me what I can do. Or who do I contact above the board?
