Scoring
The PFT Examination contains 115 multiple-choice items (100 scored and 15 pretest). You will be given two hours to complete the PFT Examination.

For specific exam content, refer to the Detailed Content Outline.

Admission Requirements
To qualify for the PFT Examination, you must be 18 years of age or older and meet one of the following requirements:

Have a minimum of an associate degree from a respiratory care education program that is supported or accredited by the Commission on Accreditation for Respiratory Care (CoARC); or
Be a Certified Respiratory Therapist (CRT) or Registered Respiratory Therapist (RRT) credentialed by the NBRC; or
Complete 62 semester hours of college credit from a college or university accredited by its regional association or its equivalent, including college credit level courses in biology, chemistry and mathematics. You must also have at least six months of clinical experience* in the field of pulmonary function technology prior to applying for the PFT Examination; or
Be a Certified Pulmonary Function Technologist (CPFT).

* Clinical experience is defined as a minimum of eight hours per week for a calendar year in pulmonary function technology under the supervision of a Medical Director of a pulmonary function laboratory or a special care area acceptable to the NBRC. Clinical experience must be completed before you apply for this examination.

A free PFT practice examination is available so you can familiarize yourself with the content and types of questions that will be included on the credentialing exam.

Self-Assessment
Anyone planning to take the PFT Examination can assess how they will perform before actually attempting the examination by taking the official NBRC Self-Assessment Examination (SAE). The feedback from the SAE provides an opportunity to evaluate and remedy less-than-desirable examination performance before taking the credentialing examination. The official SAEs are the only products that provide the respective examination committees’ rationale for the best response to each question.

Official SAEs are only available in web-based format for purchase online through the NBRC’s testing agency, PSI. PSI’s e-store offers all currently available NBRC web-based SAEs for purchase online.

To take an online SAE, you must have:
• A compatible internet browser such as the current version of Internet Explorer, Chrome, Firefox or Safari. Other browsers may not work.
• Cookies and scripting must be enabled.
• Pop-up blocking must be disabled.

After your order is placed, you will receive a confirmation e-mail with specific instructions guiding you through the examination process. The e-mail contains your private password that allows you to receive individualized feedback on your performance. You will have 90 days from the time you receive your confirmation e-mail to complete the examination.

Please note: If you purchase an NBRC SAE, your credit card statement will reflect a purchase from LXR.
