ACCS Questions and Answers

What is the ACCS exam?

The Adult Critical Care Specialty (ACCS) exam is a credentialing test administered by the National Board for Respiratory Care (NBRC) for registered respiratory therapists. Passing earns the RRT-ACCS credential, recognizing advanced competency in managing adult critically ill patients in ICU and emergency settings. It validates skills in ventilator management, hemodynamics, and advanced airway care.

What format does the ACCS exam use?

The ACCS exam is a computer-based, multiple-choice test delivered at Pearson VUE testing centers across the United States. Each question offers four answer choices with one correct response. The exam uses a linear format, meaning all candidates receive the same number of questions, and results are provided immediately after completion.

What topics does the ACCS exam cover?

The ACCS exam covers three main content areas: patient assessment, ventilation and oxygenation support, and therapeutic procedures. Specific topics include arterial blood gas interpretation, mechanical ventilation strategies, hemodynamic monitoring, ECMO, airway management, sepsis protocols, and pharmacology. Roughly half of questions focus on ventilatory support and critical care interventions.

Who is eligible to sit for the ACCS exam?

Candidates must hold an active RRT credential from the NBRC and meet one of two pathways: at least two years of clinical experience with a minimum of 3,000 hours caring for adult critically ill patients, or completion of an accredited adult critical care respiratory therapy education program within the past four years.

How do I register for the ACCS exam?

Registration is completed through the NBRC website at nbrc.org by creating an account, submitting an application, and paying the examination fee. Once the NBRC approves eligibility, candidates receive authorization to schedule their test date at any Pearson VUE testing center. Applications typically process within 10 business days.

How should I prepare for the ACCS exam?

Effective preparation includes reviewing the NBRC Detailed Content Outline, studying adult critical care textbooks like Egan's Fundamentals of Respiratory Care, and completing practice tests that mirror the exam format. Focus on mechanical ventilation modes, ABG interpretation, and ACLS protocols. Many candidates also attend AARC review courses or use Kettering and Lindsey Jones study materials.

How is the ACCS exam scored?

The ACCS exam uses a scaled scoring system ranging from raw correct answers converted to a standardized score. Candidates receive a pass or fail result along with performance feedback across content categories. The NBRC sets the cut score through criterion-referenced standard-setting, ensuring consistency across different test forms and administrations.

Can I retake the ACCS exam if I fail?

Yes, candidates who do not pass may retake the ACCS exam after a 30-day waiting period. A new application and full examination fee are required for each attempt. The NBRC allows unlimited retakes as long as eligibility requirements remain current, though reviewing weak content areas identified on the score report is strongly recommended.
