Each category of NFPA 1021 is divided into:

• A. Interpersonal, verbal, and nonverbal skills
• B. Lists of every duty that may be assigned to a new or veteran company officer
• C. Promotional schedules based on time served in the fire and emergency services
• D. Job performance requirements (JPR) that guide the officer in the performance of these duties

Answer: (D)

NFPA 1021 organizes each category around Job Performance Requirements that guide the officer in performing the duties. These JPRs spell out the specific tasks, knowledge, and skills an officer must demonstrate, with clear performance criteria and indicators that can be observed and measured. This structure provides a consistent standard for training, evaluation, and promotion across departments. That’s why this option is the best fit: the content is built around JPRs that define how to perform the duties, not just a list of duties, schedules, or a focus on a single skill area.
