Can I get a Texas water license without a high school diploma?
Yes. If you do not have a high school diploma or GED yet, a provisional Class D water license lets you start. The application is $74 and the license is valid for two years, during which you finish your diploma or GED and upgrade to the full Class D.

The provisional path
The provisional Class D exists so a lack of a diploma does not keep you out of the field. You apply, take the same Class D exam, and begin working while you complete your education.
The two-year clock
The provisional license is good for two years. Before it ends you must finish the high school diploma or GED and convert it to the full Class D, or it lapses.
