Each individual successfully completing driver education must have earned passing grades in 5 credits at the time of certification, with at least 2 of these credits in separate areas of English, Mathematics, Science, or Social Studies, in order to receive his/her Blue Certificate. This includes out-of-state students or individuals relocating into Delaware under the age of eighteen. You can contact your high school driver education teacher, high school counselor, or principal to verify your eligibility status.
