What is the Exam?

The Registered Pulmonary Function Technologist (RPFT) exam is an advanced credentialing assessment administered by the National Board for Respiratory Care (NBRC). It objectively evaluates the specialized knowledge, technical skills, and clinical abilities required of advanced pulmonary function technologists. The exam validates a candidate's mastery of complex physiological measurements—such as spirometry, lung volumes, and diffusing capacity—ensuring they can accurately assist in diagnosing restrictive and obstructive pulmonary diseases.

Earning the RPFT credential signals to employers, peers, and patients that a practitioner is committed to the highest standards of excellence in respiratory diagnostics and patient care.

Exam Format and Passing Score

Familiarizing yourself with the structure of the exam is critical for managing your pace on test day. The RPFT exam utilizes a computer-based format with the following specifications:

• Total Questions: 115 multiple-choice questions (100 scored questions and 15 unscored pretest items used for future test development).

• Time Limit: 2 hours (120 minutes).

• Passing Score: The NBRC uses a dual cut-score system. Achieving the lower cut score (a raw score of 75) earns the baseline Certified Pulmonary Function Technologist (CPFT) credential. Candidates must achieve the higher, dynamically scaled cut score to earn the advanced RPFT credential.

Core Exam Topics / Categories

The examination evaluates a candidate's thinking processes across three cognitive levels: recall, application, and analysis. The core content is divided into the following primary categories:

• Instrumentation and Equipment: Setting up, maintaining, and calibrating sophisticated medical equipment, performing stringent quality control, and troubleshooting technical errors.

• Patient Assessment and Testing Procedures: Selecting appropriate test protocols, safely executing clinical procedures, and evaluating the validity and repeatability of patient test results.

• Data Management and Interpretation: Accurately calculating clinical results, selecting the appropriate demographic reference ranges, and analyzing the reliability of data to support diagnostic outcomes.

• Clinical Management and Safety: Ensuring patient safety during testing, recognizing contraindications, and adhering to strict infection control protocols.

Career Opportunities

Acquiring the RPFT certification provides a significant competitive advantage in the healthcare job market, opening doors to advanced clinical and leadership positions. Professionals holding this specialized credential can pursue highly sought-after roles, including:
