What is a Certified Pool Operator (CPO)?

A Certified Pool Operator (CPO) is a swimming pool and hot tub professional who has completed specialized training and passed the CPO exam, earning a CPO certificate that demonstrates professional credibility in the aquatics industry. Earning the CPO certificate is recognized as the industry standard for pool and spa professionals. CPO certification ensures that pool operators are knowledgeable in pool maintenance, water chemistry, safety regulations, and problem-solving in real-world pool management scenarios.

Enhanced Safety: Certified operators ensure proper water balance, chemical handling, and facility safety, helping to protect public health by maintaining safe aquatic environments.
Career Advancement: CPO Certification enhances your credibility and opens doors to higher-level positions within the aquatics maintenance & management fields.

How to Become a Certified Pool Operator

Step 1: Choose an Approved CPO Training Provider

Ensure that the training provider you are searching for is authorized by the Pool & Hot Tub Alliance (PHTA), the official certifying body, to teach CPO courses. Registration with an approved provider is required before starting the course.

Pool Training Academy is a leading provider, known for their highly qualified, certified instructors and simple, practical training methods. Each class is led by an experienced instructor.

Step 2: Decide Between In-Person or Online CPO Classes

In-Person Classes: This format is ideal for hands-on learners and those who prefer the more traditional style of instruction, with classes held on scheduled days.
Online Courses: This format offers virtual delivery, allowing students to learn at their own pace, making it great for busy professionals needing flexible learning schedules.

Some online options also include a live class component, providing real-time instruction and interaction with an instructor.

Both formats culminate with the CPO exam and provide the exact same certification. You just want to choose the learning path that fits your needs better.

Step 3: Complete the CPO Course

The course typically spans 2 days (Though online only requires 1-day in a Zoom class) and includes multiple elements such as textbook study, video modules, and practice exams. It covers essential topics like:

Water chemistry and balancing
Pool calculations (volume, dosage)
Filtration systems
Circulation and hydraulics
State and federal regulations
Pool safety protocols
Troubleshooting common pool issues
Spa management and spa operations
Pool construction
Local codes and industry standards

Practical techniques are taught by certified instructors, and all essential topics are covered to ensure comprehensive training.

Step 4: Pass the CPO Exam

The CPO final exam is open book and open note, focusing less on how much knowledge you can memorize and more on your ability to use resources like the Pool Operator Handbook and your notes to solve practical swimming pool and hot tub problems. The final exam is administered by a certified instructor to ensure credibility and adherence to standards. Typically you can take the final exam on the same day as your course, or complete both the live Zoom session and exam in a convenient one-day session. In order to provide you with the most time efficient training, this is how Pool Training Academy offers our programs.

If taking the course online or in a hybrid structure, students may be required to complete the Pool Operator Primer, a self-paced foundational module series of videos, before attending the live class or taking the final exam.

The policy on exam retakes follows Pool & Hot Tub Alliance (PHTA) guidelines, and unlimited exam attempts may not be available—typically, a limited number of retakes is allowed. At the writing of this guide, a student is allowed 2 additional retakes if they are not successful the first time.

In order to pass the exam, you’ll need to:

Score at least as 74%
Demonstrate your ability to perform simple pool math equations and searching skills by using your handbook and notes

Your certificate is generally valid for 5 years in most states. Successful completion is required to receive certification and maintain your professional credentials.
