Is it legal for driving school to give students priority in driving test?

Not illegal.

According to the French Open, the state does not explicitly require students to take the driver's license first, and local policies and driving schools will give priority to students to learn first. After all, students only have more time to learn driving in winter and summer vacations, and the number of students is relatively large and concentrated. In order to meet the desire of school-age students to learn driving as much as possible, some local driving administrations have determined a "normalized" green channel driving test mode that combines "priority arrangement" and "special examination" for school-age students in winter and summer vacations. That is, on the one hand, it is a priority arrangement. School-age students during the winter and summer vacations are not subject to the registration time limit. As long as they meet the training standards and have the conditions to apply for the exam, they all have the right to arrange the exam first. On the other hand, it is overtime to organize special examinations. When the number of school-age students who meet the registration requirements meets the requirements of an exam during the winter and summer vacations, they will use the weekend break to work overtime in the form of special sessions, so that students can take the green channel exam. School-age students can enjoy the qualification to take the green channel exam as long as they rely on the Admission Ticket of the College Entrance Examination or the Student ID Card of colleges and universities and the certificate issued by the driving school that the hours and training quality meet the examination standards. It can be seen that there is no law that students can take a driver's license first, but it is not illegal.
