Booking Through Us vs. Finding an Examiner on Your Own
On your own
- You must confirm the training school is genuinely APA-accredited — many “certificates” come from unaccredited courses.
- You must check that memberships are real and have not lapsed.
- You must verify the state licence with the Texas Department of Licensing and Regulation (TDLR) yourself.
- Few people think to ask about professional liability insurance.
- A sole operator often has no published standards and no complaints route.
- You may pay in full for a test your situation is not suitable for.
