Other jurisdiction
The existing license and any examination required by its issuing jurisdiction are applicant conditions, not Texas-exam leaves.

The existing license and any examination required by its issuing jurisdiction are applicant conditions, not Texas-exam leaves.

Official no-examination sources

Expedited military licensure after holding the same Texas license within five years
No examination is required for this applicant pathway.
Eligibility
Be a military service member, veteran or spouse and have held the same Texas license within five years before application. Submit the license application, military supplemental application and status or marriage documentation. Criminal-history review applies; TDLR may waive additional prerequisites.
Implementation conflict
TDLR's Military Transfer webpage says: "You may be required to successfully complete any exams that are part of the license requirements." The current 16 TAC §60.514(e) expressly exempts qualifying applicants from the applicable examinations; that regulation controls this route.

Military renewal after expiration during active duty
No examination is required for this applicant pathway.
Military status
The license expired while the license holder served on active duty. Receive two additional years to complete renewal requirements, including continuing education. Provide evidence of service; renewal fees still apply and the statutory late-penalty exemption applies when established. The separate five-year previous-license route governs applicants qualifying for that route.

Expedited military licensure using a similar out of state license
No examination is required for this applicant pathway.
Eligibility
Be a military service member, veteran or spouse; hold a current out-of-state license with similar scope and be in good standing. Submit the license application, military supplemental application, status or marriage evidence, license copy and evidence of standing. TDLR determines similar scope, performs a criminal-history review and may waive other prerequisites.
Implementation conflict
TDLR's Military Transfer webpage says: "You may be required to successfully complete any exams that are part of the license requirements." The current 16 TAC §60.512(e) expressly exempts qualifying applicants from the applicable examinations; that regulation controls this route.

Licensure by evaluation of an existing out of state license — Master Driller (A)

All of the following:

Application
Submit the department-approved application and supporting documents; pay applicable fees and satisfy all initial requirements within one year of filing. Examination eligibility follows TDLR verification.
Background
Answer criminal-history and disciplinary-history questions and supply the questionnaires required by the July 2026 application. TDLR reviews criminal history and may deny the application.
Endorsement experience
W: 15 water wells; M: 50 monitor wells; N: 50 injection wells; D: 50 dewatering wells; C: 50 closed-loop geothermal wells. Master A requires all five endorsements (215 qualifying drillings). 16 TAC §76.21(d)-(e).
Endorsement selection
Master Driller (A): obtain every W, M, N, D and C endorsement; the exams are retained even when previously passed.
Experience
At least two years of relevant drilling experience under a licensed driller; document supervised work. 16 TAC §76.21(a).
Out of state license
Submit a current license and identifying information for its issuing authority. TDLR determines substantial equivalence under 16 TAC §60.34. Another jurisdiction's own examinations and license are applicant conditions.
Reciprocity agreement
16 TAC §60.38 applies only if a licensing reciprocity agreement covers the applicant. Eligibility includes a license held at least one year, not obtained by reciprocity, good standing, qualifying original examination or equivalent qualifications, and no disqualifying history or pending complaint. This survey does not assert that a particular agreement has been executed.
Score
A passing grade is 70%; PSI eligibility is valid for one year from approval.
Waiver
Texas Occupations Code §1901.162 and §51.4041(b) allow waiver of licensing prerequisites after an equivalence or reciprocity evaluation; waiver is discretionary. The standard Texas exams remain identified unless TDLR grants an applicable waiver.
