I have had this happen numerous times with my freshmen, whose parents are used to daily emails from middle school teachers. I explained to the parents that the student is in high school and will be held accountable for themselves. I also told the parent that the student received an agenda at the beginning of the school year to keep track of assignments and due dates. I also recommend that parents sign up for Remind 101 to receive text updates.

I think that I would try to find a solution that involves both the parents and the student. This way the student is being held accountable for some responsibility and the parents can also check and manage the student's work. For example, enforcing use of a student planner by having signatures may be a way to include both parties. The student must write down all assignments and due dates, then the parents can sign that they have reviewed this information, and when the teacher receives the assignment he/she can sign off that it has been turned in. This is kind of elementary, but may actually work to hold the student accountable and teach responsibility.

Sometimes it is better to work with the parents and give in a little to get what you want. Try giving the parents what they want, emailing them the assignments, but with a timeline where you will phase out the parent email as the student becomes more independent.
