The Driver Eligibility Certificate (DEC) is issued by the principal, or his/her designee, of the school that you attend. The DEC is only valid for thirty (30) days, so do not request one if you are not going to apply for your learner's permit within 30 days.
If you are home schooled, you must contact the Division of Non-Public Education in Raleigh, NC at 919-733-4276.
