No I don't think anyone has the right to refuse a child his/hers education. They can however choose if it's going to be home schooling or not. This also depends every much on the laws in the different states.
Go to the school, bringing necessary documents to prove you are the parent, and find out if the child is still attending school there.

No, a public school cannot prevent a parent from coming to the office (but not to the classroom) unless that parent is unruly and causing trouble then that school has the right to ban the parent from coming into the school.
If a teenager refuses to go to school, a parent should first try to understand the reason behind the refusal. They should communicate openly with their teenager, seek help from school counselors or mental health professionals if needed, and set clear consequences for not attending school. It is important for the parent to address the issue promptly to prevent long-term negative impacts on the teenager's education and future opportunities.

If you are over 18, you are legally an adult and do not need to attend high school, although it is harder to get a job. If you are a minor (under 18), then your parents will be held responsible for you not attending school, and I believe if you don't, you or your parents can get into legal trouble.
That would depend on the circumstances. If there is not a legal, acceptable reason for the child not attending school, the non-custodial parent could file a motion for modification of the original custody order based on the same.
