NFPA CWBSP Exam Syllabus Topics:

Topic	Details
Topic 1	Design System Layouts: In this part of the exam, Water-Based Fire Protection System Designers will be tested on their ability to design appropriate water-based fire protection systems. Designers must determine system types, evaluate water supply, and design layouts, including hangers and bracing. The exam will assess compliance with contracts, codes, and standards, as well as coordination with other systems.
Topic 2	Hydraulic Calculations: The hydraulic calculations topic evaluates a designer’s understanding of hydraulic formulas and design methods. Designers will be tested on their ability to apply these principles, particularly in evaluating the hydraulically most remote calculation area. This topic is critical to ensuring the efficiency and effectiveness of the fire protection system.
Topic 3	Survey Existing Systems: This topic tests the designer’s skills in reviewing and assessing existing fire protection systems. Designers will be evaluated on their ability to evaluate system components, identify needs, and verify compliance with codes. Additionally, they must demonstrate competence in understanding inspection, testing, and coordinating interfaces between systems to ensure compliance and system adequacy.
Topic 4	Project Development: In this topic of the CWBSP exam, Water-Based Fire Protection System Designers will be assessed on their ability to understand project scope, identify occupancy types, and review contract documents. Designers will need to demonstrate proficiency in evaluating plans, specifications, and submittal approval requirements, ensuring their capability to manage the foundational stages of a water-based fire protection system design.
