There are changes in the DPS forms. Anyone under 18 will be using DPS form DL-14B to apply for the first-time driver license or identification card. For those over 18 will be using DPS form DL-14A to apply for the first-time driver license or identification card. When you passed your driving test at the driving school and ready to process driver license at the DPS, you will need to fill out the same form again, and you will check the box for renewal instead of the original. Here is the link to both of the forms:
