Is the CPO Exam Hard? Here’s What You Should Know

Before we get into it, this article is part of a larger series called The Ultimate Guide To Becoming a Certified Pool Operator. 

One of the most common questions we get asked at Pool Training Academy is, “Is the CPO exam hard?” It’s a fair question. Anytime there’s a test involved, people naturally worry about how difficult it might be. But the truth is, the Certified Pool Operator (CPO) exam isn’t designed to prove how much random pool knowledge you have memorized. Instead, it’s built to test a much more practical skill: your ability to find the correct answers to real-world swimming pool problems using trusted resources.

When you’re out in the field, no one expects you to have every formula or regulation number memorized. What matters is knowing where to look and how to find accurate information when you need it. The CPO exam reflects this reality. It’s not a test of trivia—it’s a test of resourcefulness.

The Good News: The CPO Exam Is Open Book & Open Note

Here’s some relieving news for anyone nervous about taking the exam: the CPO test is completely open book and open note. This means you can use your Pool Operator Handbook, your class notes, and any other legitimate resources your instructor provides during the test.

Why? Because a good CPO instructor wants to ensure you know how to use the reliable resources at your disposal to solve problems. The ability to find trustworthy and accurate information is far more important than memorizing a long list of numbers. In fact, when you take your CPO course with Pool Training Academy, we specifically teach you how to navigate these resources effectively, making you field-ready from day one.

Don’t Fear the Math—It’s Manageable

Yes, there is some math on the CPO exam—but don’t let that intimidate you. If you can comfortably add, subtract, multiply, and divide, you’re already in good shape. There’s no need to memorize formulas or complex calculations because every formula you’ll need is provided in the Pool Operator Handbook.

The math problems are practical and directly related to daily pool operations, like calculating water volume or chemical dosages. As long as you follow along during the math portions of your class and practice using the formulas in your book, the math component will be very approachable.

You Have a Safety Net: Retake Opportunities Available

Test anxiety can strike even the most prepared students. That’s why it’s important to know that you are allowed to retake the exam if needed. The goal of the CPO certification isn’t to trick you or make you fail—it’s to ensure that you understand how to operate pools safely and effectively.

If nerves get the better of you during your first attempt, you’ll have another chance to demonstrate your knowledge. The process is designed to support your success, not set you up for failure.
