Nevada belongs to the interstate compact that protects military children when frequent moves and deployments change their school. It speeds up enrollment when records have not transferred yet, keeps differences in attendance rules, scheduling, sequencing, course content, grading and assessment from setting your child back, protects eligibility for educational programs and extracurricular academic, athletic and social activities, and supports on-time graduation.
Raise the problem with your school district first. If it is not resolved, submit an MIC3 assistance request, or call the Nevada points of contact at 702-799-5879 or 702-688-4330.
Your orders showing the move, and whatever school records you have from the previous district.
