CRT Practice Test

The CRT exam is administered by the National Board for Respiratory Care (NBRC), the main credentialing body for the field. They set the standards, publish the exam outline, and manage all applications, scheduling and score reporting. Testing is delivered through approved computerized testing centers across the country.

To take the CRT exam you must graduate from a respiratory therapy program accredited by CoARC and be at least 18. These programs provide the clinical and technical training needed to meet NBRC’s entry-level standards. Once you graduate, you can apply immediately.

You register on the NBRC website by creating an account, completing the application and submitting the required fee. After NBRC verifies your eligibility, you receive authorization to schedule your exam. You can then pick a date, time and test location that fits your schedule.

The CRT exam includes 160 multiple-choice questions delivered on a computer. You have three hours to finish the test. Questions cover patient assessment, therapeutic procedures, equipment, diagnostics and essential clinical decision-making skills you’ll be expected to use in practice.

The exam covers cardiopulmonary anatomy, physiology, ventilation, airway management, infection control, patient evaluation and emergency procedures. You’ll also interpret clinical data, select appropriate therapies and evaluate patient responses. The NBRC outline breaks down these areas in detail for studying.

Good preparation involves reviewing NBRC’s official content outline, taking Prephow CRT practice tests and studying core respiratory therapy textbooks. Many candidates also work through clinical scenarios and ventilation exercises to improve decision-making skills. Consistent practice helps you build confidence for test day.

The CRT credential follows NBRC’s renewal cycle, which requires credential holders to maintain continuing education or meet specific renewal steps. This system ensures respiratory therapists stay updated on new equipment, clinical guidelines and best practices throughout their career.

International candidates can take the CRT exam only if their education meets NBRC requirements, which usually means graduating from a CoARC-accredited program. Many overseas programs do not meet this standard, so international applicants often complete U.S.-based training before becoming eligible.

Passing the CRT exam proves you meet the national standard for entry-level respiratory therapy practice. Most hospitals, clinics and home-care providers require at least CRT for hiring. Earning the credential can improve job prospects, starting salary and overall career stability.
