New York belongs to the interstate compact that removes school barriers for children of military families who move often. It speeds up enrollment when records have not arrived, keeps differences between states in attendance rules, scheduling, sequencing, grading, course content and assessment from disadvantaging your child, protects eligibility for programmes and extracurricular activities, and supports on-time graduation.
Work with your school district first. If the issue is not resolved, submit an MIC3 assistance request. You can also call the New York point of contact at 845-392-6333.
Your military orders showing the move, and whatever school records you have from the previous district.
