Texas TDLR License Exam Prep

Written by a licensed pro

Not a content mill. Every guide is written by someone who holds all four of these Texas licenses and works in the field.

Sourced answer keys

Each practice answer links straight to the rule it comes from, so you learn why — not just what.

Study anywhere

Mobile-friendly guides and timed or untimed practice tests you can retake as often as you like.

Who writes this

Taught by a driller who holds all four licenses

These guides aren't written by someone reading the rulebook for the first time. They're written by a working Texas professional who has sat these exams and holds every one of these licenses — so you get what actually matters on test day, not a summary of a summary.

Licensed General Well Driller
Licensed Water Well Driller
Licensed General Pump Installer
Licensed Single-Phase Pump Installer

Every answer is still backed by a written citation to the rule or reference it comes from — experience tells you what to study, the sources prove it.
