New Hampshire belongs to the interstate compact that smooths school transitions for military children. It speeds up enrollment when records have not arrived yet, keeps differences between states in attendance rules, scheduling, grading and course content from holding your child back, protects eligibility for programs and extracurricular activities, and helps your child graduate on time.
Work with your school district first. If that does not resolve it, submit an MIC3 assistance request, or call the New Hampshire points of contact at 603-225-0855 ext. 2003 or 603-422-9572.
Your military orders showing the move, and whatever school records you have from the previous district.
