The Florida Commercial Pool Trade Knowledge Exam
The Commercial Pool Trade Knowledge exam is a required part of the Commercial Pool/Spa Contractor license in Florida, and is also sat by the Residential Pool/Spa Contractor and Swimming Pool Servicing Contractor. It is open book, like every Florida CILB exam, so the tested skill is as much knowing where to find an answer as knowing it cold.

What's on the Trade Knowledge exam
The exam follows the official DBPR content outline. These are its weighted domains — study time is best spent where the exam puts its points.
Structure & Shell
Excavation, steel, shotcrete/gunite, finishes, and decks.
Hydraulics & Circulation
Flow rates, turnover, head loss, and piping.
Equipment & Installation
Pumps, filters, heaters, and bonding/grounding concepts.
Water Chemistry
Sanitizers, balance parameters, and testing.
Code & Safety Compliance
Barriers, entrapment protection, and Florida pool code requirements.
Sample questions
Original, exam-style questions with the answer and an explanation — a taste of how LicenseReady drills the Trade Knowledge material.
What distinguishes gunite (dry-mix shotcrete) from wet-mix shotcrete when constructing a pool shell?
Gunite is a dry cement-sand mix conveyed through the hose, with water added at the nozzle
Both gunite and wet-mix shotcrete are concrete applied pneumatically at high velocity. In the dry-mix (gunite) process, the dry cement and sand mixture travels through the hose and the nozzle operator adds water at the nozzle, while in the wet-mix process the concrete is fully mixed with water before being pumped to the nozzle.

At what point in the construction of a concrete pool is the steel reinforcement installed?
After excavation and plumbing rough-in, before the shotcrete or gunite shell is applied
The reinforcing steel is tied into a continuous grid that follows the excavated shape of the pool before any concrete is placed. The shotcrete or gunite is then shot around and through the grid so the steel is fully encased within the structural shell.

Reference books you'll use
The Trade Knowledge exam is open book. These are the approved references its questions come from — tabbing them in advance is half the battle.
OSHA 1926
OSHA questions are number questions: heights, depths, distances, and hours. Tab the big subparts and trust the printed number over your memory.
Pool References
Safety and barrier questions are code lookups; hydraulics questions are formulas. Keep the formula sheet (turnover, volume, TDH) tabbed in the handbook and the barrier rules tabbed in the code.
Florida Building Code
Code questions give themselves away with words like 'minimum', 'required', or 'permitted'. Go to the code — never answer a code question from memory when the book is on the desk.
Frequently asked questions
How many questions is the Florida Commercial Pool Trade Knowledge exam?
80 questions. You have 5 hours and need 70% correct to pass.
Is the Commercial Pool Trade Knowledge exam open book?
Yes. Every Florida CILB construction exam is open book — you bring approved, tabbed reference books. The challenge is finding answers fast enough, which is why pacing and tabbing matter as much as knowledge.
What topics are on the Trade Knowledge exam?
The exam is weighted across 5 domains: Structure & Shell, Hydraulics & Circulation, Equipment & Installation, Water Chemistry, Code & Safety Compliance. Heavier-weighted domains deserve more study time.
