Pool operator requirements in Texas
Quick answer
Does Texas require a certified pool operator?
Yes. Texas Administrative Code 25 TAC 265.194(b) requires every Class A, Class B, and Class C public pool and spa to be maintained under the supervision of a properly trained and certified operator. Section 265.194(d) names three qualifying routes: the NRPA Aquatic Facility Operator, the PHTA Certified Pool Operator, and the ASPSA Licensed Aquatic Facility Technician, or an equivalent course a local regulatory authority approves.
- Certified operator required?
- Required statewide Section 265.194(b) states that all Class A, Class B, and Class C pools and spas shall be maintained under the supervision and direction of a properly trained and certified operator. The operator is not required to be on-site whenever the pool or spa is open, and one operator may be responsible for multiple pools and spas, but the name and contact information of that operator must be available to on-site staff and to the department or local regulatory authority on request.
- Certifications accepted
- CPO (PHTA), AFO (NRPA), State-specific certification, State-approved course Section 265.194(d) names three qualifying courses: the NRPA Aquatic Facility Operator (AFO), the PHTA Certified Pool Operator (CPO), and the ASPSA Licensed Aquatic Facility Technician, plus any equivalent course that requires testing, provides certification, and is approved by the local regulatory authority.
- Governing agency
- Texas Department of State Health Services (statewide rule); local regulatory authorities (county and city health departments, such as Austin Public Health and the Houston Health Department) administer permitting and inspection and may adopt equal or stricter standards
- Regulation citation
- 25 Texas Administrative Code, Chapter 265, Subchapter L (Public Swimming Pools and Spas), sections 265.181 to 265.198, implementing Texas Health and Safety Code sections 341.064 and 341.0645
- CDC Model Aquatic Health Code
- Texas has not adopted the CDC Model Aquatic Health Code by name. Section 265.181(b) instead adopts by reference the 2018 International Swimming Pool and Spa Code (ISPSC) for construction, alteration, renovation, and repair, plus the ANSI/APSP-16 suction-outlet-fitting standard and the ANSI/PHTA/ICC-7 suction-entrapment-avoidance standard, with the exclusions listed in section 265.181(d).
- Renewal / operator presence
- The rule sets no state-specific renewal cycle for the operator credential itself; a trained and certified operator keeps whichever certification qualified them current under that program's own cycle (the CPO runs nationally on five years). Section 265.181(g) lets a local regulatory authority adopt standards more stringent than the state minimum, which is why some Texas cities and counties layer extra requirements on top of the state baseline.
State-code numbers that differ from the national body of knowledge
| Requirement | Texas value | Notes |
|---|---|---|
| Pool free available chlorine | 1.0 to 8.0 ppm (ideal 2.0 to 3.0 ppm) | 25 TAC 265.193(b) required chemical levels table |
| Spa free available chlorine | 2.0 to 8.0 ppm (ideal 3.0 ppm) | 25 TAC 265.193(b) |
| pH | not less than 7.0, ideal 7.2 to 7.6, maximum 7.8 | 25 TAC 265.193(b) |
| Cyanuric acid | ideal 30 to 50 ppm, maximum 100 ppm | 25 TAC 265.193(b) and 265.193(o), banned in indoor pools, spas, and therapy pools by 265.193(c) |
| Disinfectant and pH testing frequency, Class A/B pools open for use | every two hours | 25 TAC 265.193(n)(1)(A) |
| Lifeguards required | minimum two, at Class A pools during competitive events and any Class B pool whenever it is open | 25 TAC 265.191(a) |
Texas answers the “do I need a CPO” question more directly than most states: yes, the state itself requires a trained and certified pool operator, and it names the CPO as one of three qualifying routes. That single rule, 25 TAC 265.194(b), is worth knowing cold if you are studying for the exam to work at a Texas pool, because it also tells you exactly which certifications satisfy it and which do not need to.
Who this applies to
This page covers public pools and spas as Texas defines them: any pool or spa maintained for public recreation, swimming, diving, or aquatic sports, publicly or privately owned, with or without a fee. The rule sorts them into three classes. Class A covers pools used for accredited competitive events (FINA, USA Swimming, USA Diving, NCAA, or state high school association events), which may also be used for recreational swimming. Class B covers any pool open to the general public for recreation, with or without a fee. Class C covers everything else operated in conjunction with lodging (hotels, motels, apartments, RV parks), youth camps, property owner associations, private clubs, or schools and colleges for their own occupants, members, or students. Residential pools, artificial swimming lagoons, and floatation systems are excluded.
Does Texas require a certified pool operator?
Yes. Under 25 TAC 265.194(b), “all Class A, Class B, and Class C pools and spas shall be maintained under the supervision and direction of a properly trained and certified operator.” That covers essentially every public pool in the state, not just a subset. The operator does not have to be physically present whenever the pool is open, and one operator can be responsible for multiple facilities, but their name and contact information have to be on file and available to on-site staff, property managers, and inspectors on request.
Which certification counts
Section 265.194(d) names the qualifying routes directly:
- The NRPA “Aquatic Facility Operator” course.
- The PHTA “Certified Pool Operator” course.
- The ASPSA “Licensed Aquatic Facility Technician” course.
- An equivalent course that requires testing, provides certification, and is approved by the local regulatory authority.
So the CPO is explicitly accepted, but it is one of three named certifications rather than the only one, and a fourth path exists if your local health department signs off on an equivalent program. Compare the CPO and AFO in our CPO vs AFO guide, and see how to become a CPO for the course-plus-exam path.
The governing law, in plain terms
- 25 TAC Chapter 265, Subchapter L (Public Swimming Pools and Spas) is the rule, implementing Texas Health and Safety Code sections 341.064 and 341.0645.
- Section 265.181(b) adopts the 2018 International Swimming Pool and Spa Code (ISPSC) by reference for construction, alteration, renovation, and repair, along with the ANSI/APSP-16 suction-outlet-fitting standard and the ANSI/PHTA/ICC-7 suction-entrapment-avoidance standard. Section 265.181(d) lists specific ISPSC provisions Texas does not adopt.
- Section 265.194 (Operation and Management of Pools and Spas) is where the operator-certification requirement lives, alongside operator responsibilities and documentation duties.
- Section 265.197 gives the department or a local regulatory authority the right to enter and inspect at all reasonable times without advance notice.
- Section 265.181(g) lets a local regulatory authority adopt standards more stringent than the state minimum, which is why some Texas cities and counties, including Austin and Houston, run their own environmental health pool programs layered on top of this baseline.
State-code numbers that trip up test-takers
Texas’s required chemical levels, from the 265.193(b) table: pool free available chlorine runs 1.0 to 8.0 ppm with an ideal band of 2.0 to 3.0 ppm, spa free available chlorine runs 2.0 to 8.0 ppm with an ideal of 3.0 ppm, pH must stay not less than 7.0 with an ideal of 7.2 to 7.6 and a maximum of 7.8, and cyanuric acid has an ideal band of 30 to 50 ppm with a hard maximum of 100 ppm (and is banned outright in indoor pools, spas, and therapy pools). Testing cadence is stricter than the generic body of knowledge for staffed facilities: Class A and B pools open for use must test disinfectant and pH every two hours under 265.193(n)(1)(A). The pool-math trainer and the pool chemistry calculator both work from these kinds of ranges, so drilling them there transfers directly.
How to comply in practice
- Classify your pool. Class A, B, and C each carry their own lifeguard, enclosure, and signage rules on top of the shared operator requirement.
- Earn or hire a trained and certified operator. The CPO, AFO, and ASPSA Licensed Aquatic Facility Technician all satisfy 265.194(b); pick the course your employer or local authority prefers.
- Keep the operator’s contact information on file and available to on-site staff and to the department or local regulatory authority.
- Check your local health department. Cities and counties such as Austin and Houston may layer additional requirements on top of the state minimum under 265.181(g).
Keep studying
The math the exam tests does not change by state, and it is what fails most candidates. Drill it on the pool-math trainer, take the free practice test, or check the pool chemistry calculator for turnover and dosing against ranges like Texas’s. Compare Texas with other states as they publish in the state requirements matrix.
