Hawaii belongs to the interstate compact that smooths school moves for military children. It speeds up enrollment when records have not caught up, stops differences between states in attendance rules, scheduling, course content, grading or assessment from setting your child back, protects eligibility for programs and extracurricular activities, and helps your child graduate on time.
Raise the problem with your school district first. If it is not resolved, submit an MIC3 assistance request. You can also call the Hawaii points of contact at 808-307-3900.
Your military orders showing the move, and whatever school records you have from the previous district.
