Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
Your only recourse now is an appeal to the school board I am afraid. This will come down to your grandson's word against the teacher's word and absent any evidence to the contrary the school board will have to make their determination based on which of the parties they find most credible. If the school board denies your grandson's appeal, then I am afraid that there is no other legal recourse in this matter.
