1.1 About the AE-C Examination

About the AE-C Examination

Quick Answer: The Certified Asthma Educator (AE-C) examination is a 175-question, 3.5-hour computer-based exam administered at PSI assessment centers. Of the 175 questions, 150 are scored and 25 are unscored pretest items. The NBRC reports results only as pass or fail and does not publish the AE-C cut score. The exam is open to licensed healthcare professionals as well as non-licensed educators with 1,000 hours of verified asthma education experience, and the resulting credential is valid for 5 years.

The Certified Asthma Educator (AE-C) credential represents the gold standard in interprofessional asthma education, clinical assessment, and care coordination in the United States. Created by the National Asthma Educator Certification Board (NAECB) in 2002 and acquired outright by the National Board for Respiratory Care (NBRC) effective September 1, 2022, the credential validates that an educator possesses the specialized knowledge, clinical reasoning, and counseling skills necessary to optimize health outcomes for individuals living with asthma.

Unlike disease-specific certifications limited to a single professional group, the AE-C credential is intentionally multidisciplinary. Certified educators include registered nurses, respiratory therapists, nurse practitioners, pharmacists, physicians, physician assistants, health education specialists, physical and occupational therapists, and clinical social workers. This interprofessional design reflects modern chronic care models, where coordinated teams partner with patients and families across primary care clinics, pulmonary specialty practices, emergency departments, inpatient units, schools, and community health organizations.

Exam Structure and Scoring Architecture

The AE-C examination is delivered exclusively as a standardized, computer-based assessment. Candidates receive 3.5 hours (210 minutes) of active testing time to complete the examination. Because the test contains 175 questions, candidates have an average of 1.2 minutes (72 seconds) per question, requiring efficient pacing and decisive clinical decision-making.

Scored vs. Pretest Questions

The 175 multiple-choice questions are categorized into two distinct groups:

• 150 Scored Questions: These questions directly measure candidate competency across the four blueprint domains and determine your final score.
• 25 Pretest Questions: These unscored items are interspersed seamlessly throughout the test. Pretest items allow the testing committee to gather statistical performance data (such as item difficulty and point-biserial discrimination indices) before items appear as scored questions on future examination forms. Pretest questions are completely indistinguishable from scored questions; therefore, candidates must approach every question with equal diligence.

How the Passing Standard Works

The NBRC does not publish a passing score, percentage, or cut score for the AE-C Examination. Its published scoring information states only that the exam contains 175 items (150 scored, 25 pretest) and directs candidates to the Detailed Content Outline. Third-party test-prep sites that quote a specific number (commonly "75") are not citing an NBRC source — treat any such figure as unverified.

What the NBRC does confirm is the type of standard:

• Criterion-referenced, not norm-referenced. You are measured against a fixed competency standard, not ranked against other candidates. Every candidate in a testing window could pass, or none could.
• Equated across forms. Because multiple test forms circulate and item difficulty varies slightly, the raw number of correct answers needed shifts marginally between forms. The underlying competency standard does not move.
• Reported as pass/fail. Your pass/fail result appears on screen when you finish, and PSI emails a score report — including performance feedback by content area — within 24 hours.

Practical implication: Because no official percentage exists, do not study toward "getting 75 right." Aim for consistent mastery across all four content areas, and weight your effort toward Asthma Management, which alone supplies 71 of the 150 scored items.

Blueprint Content Domains and Weightings

The AE-C examination blueprint is developed through extensive job task analyses conducted by the NBRC and NAECB. The examination assesses candidate competence across four core domains:

Detailed Breakdown of Exam Domains

1. Domain 1: The Asthma Condition (20% / 30 items): This domain tests foundational pathophysiology, anatomy, and disease progression. Topics include normal versus asthmatic airway morphology, cellular inflammation (Type 2-high vs. non-Type 2 pathways, eosinophils, mast cells, cytokines IL-4, IL-5, IL-13, and TSLP), bronchial hyperresponsiveness, smooth muscle hypertrophy, subepithelial fibrosis, and airway remodeling. Candidates are tested on common allergic triggers (dust mites, cockroaches, animal dander, molds, pollens), environmental irritants (secondhand smoke, vaping, particulate matter PM2.5, ozone), physiological triggers (viral infections, exercise, stress), and comorbid conditions (allergic rhinitis, rhinosinusitis, GERD, OSA, and vocal cord dysfunction/inducible laryngeal obstruction).

2. Domain 2: Assessment of an Individual with Asthma and Family (23% / 34 items): This domain focuses on diagnostic evaluation, monitoring, and educational needs assessment. Key competencies include taking a detailed clinical history, identifying physical signs of acute distress (retractions, tachypnea, pulsus paradoxus, silent chest), interpreting pulmonary function testing (spirometry quality criteria, FEV1, FVC, FEV1/FVC ratio, and bronchodilator reversibility of ≥12% and ≥200 mL), peak expiratory flow (PEF) monitoring, fractional exhaled nitric oxide (FeNO), and methacholine challenge testing. Candidates must also demonstrate proficiency in classifying asthma severity (impairment vs. risk), assessing asthma control using validated instruments (Asthma Control Test [ACT], Asthma Control Questionnaire [ACQ]), and evaluating health literacy using the teach-back method.

3. Domain 3: Asthma Management (47% / 71 items): Comprising nearly half of the entire examination, this domain covers therapeutic interventions, pharmacology, device technique, and patient self-management education. Key areas include short-acting beta2-agonists (SABAs), inhaled corticosteroids (ICS), combination therapies (ICS-LABA), Single Maintenance and Reliever Therapy (SMART/MART), long-acting muscarinic antagonists (LAMAs), leukotriene receptor antagonists (LTRAs), biologic therapies targeting severe asthma (anti-IgE, anti-IL-5, anti-IL-5Rα, anti-IL-4Rα, and anti-TSLP), systemic corticosteroids, and immunization protocols. Crucially, this domain tests delivery device mastery (pMDIs, valved holding chambers, DPIs, SMIs, nebulizers), indoor environmental control, smoking cessation (the 5 A's framework), and writing individualized Asthma Action Plans using green, yellow, and red zones.

4. Domain 4: Organizational Issues (10% / 15 items): This domain focuses on community-level interventions, program administration, and professional ethics. Topics include conducting community needs assessments, addressing healthcare disparities, implementing evidence-based public health models (such as the CDC EXHALE strategies), managing multidisciplinary care teams, adhering to legal and confidentiality frameworks (HIPAA, FERPA in schools), executing quality improvement initiatives (PDSA cycles), and navigating billing and reimbursement mechanisms (CPT codes 98960–98962 for self-management education).

Eligibility Pathways

To sit for the AE-C examination, candidates must fulfill one of two primary eligibility routes established by the credentialing board:

Route 1: Licensed or Credentialed Healthcare Professionals

Candidates must hold a current, active, unrestricted license or credential issued in the United States in one of the disciplines the NBRC lists by name. The list is closed — a related credential that does not appear on it does not qualify under this route:

Candidates applying under this route may apply online through the NBRC Practitioner Portal.

Route 2: Practice-Experience Pathway (1,000 Hours)

Applicants who do not hold one of the credentials above may sit for the exam with a minimum of 1,000 hours of direct patient asthma education, counseling, or coordinating services completed before applying. The NBRC sets no degree requirement and no look-back window for these hours — any claim that a bachelor's degree or a 2-to-3-year recency window is required is not an NBRC rule. Applicants using this route must submit a paper application with employment listed and signature verification from a supervisor; the online application is not available for this pathway.

Application Verification & Audits: All applications are subject to random audits by the NBRC. Candidates selected for audit must submit official primary source verification of their professional licenses, academic transcripts, or documented hours signed by an authorized clinical supervisor.

Testing Logistics: Scheduling and PSI Assessment Centers

The AE-C examination is delivered by PSI Services LLC at more than 300 assessment centers across the United States, open Monday through Saturday (excluding selected holidays). The NBRC does not advertise a remote-proctored option for the AE-C Examination; plan on in-person testing at a PSI center. Candidates testing outside the United States pay an additional international testing fee of $150.

Four scheduling rules regularly catch candidates out:

Reapplicants pay the reduced $250 examination fee rather than the $350 new-applicant fee; AARC members receive a $40 discount on a first-time application only.

Examination Day Guidelines

• Identification Requirements: Candidates must present two valid forms of identification. The primary ID must be government-issued, unexpired, contain a recent photograph, and have the candidate's signature (such as a driver's license, passport, or state ID card). The secondary ID must display the candidate's name and signature.
• Workstation Rules: No personal belongings, cell phones, smartwatches, notes, or food/drinks are permitted in the testing area. Lockers are provided at testing centers.
• On-Screen Examination Features: The testing platform includes a built-in standard calculator, a digital countdown clock showing remaining time, a question-flagging feature to mark uncertain items for later review, and a review screen displaying unanswered and flagged questions.
• Score Reporting: Your pass/fail result is displayed on screen as soon as you finish. PSI emails the official score report — including feedback on your performance in each content area — to the address on file within 24 hours. If it does not arrive, contact PSI rather than the NBRC.

Credential Maintenance and 5-Year Recertification

The AE-C credential remains valid for 5 years from the date of passing. To ensure that certified asthma educators maintain currency with rapidly evolving pharmacological guidelines, clinical evidence, and diagnostic standards, educators must renew their certification every 5 years through one of two pathways:

Every AE-C holder is required to participate in the Credential Maintenance Program (CMP). The CMP fee is $125 for the five-year cycle, billed as $25 per year. Three compliance options exist.

Option 1: Quarterly Assessments and/or Continuing Education

The number of CE credits you owe is not fixed at a single number — it is driven by how you perform on the NBRC's quarterly online assessments, which sort you into one of three zones:

Your Practitioner Portal dashboard tracks assessment progress and displays your current CE requirement. For educators holding only the AE-C, the CEUs must be in content areas specific to asthma education, matched to the Detailed Content Outline. Acceptable providers include, among others, ACCME- and ACPE-accredited providers, AAFP, the American Academy of Pediatrics, AAPA, AANP, AARC (CRCE credit), ACSM, the American Lung Association, AMA, ANA, ANCC, AOTA, APTA, the American Psychological Association, the Association of Asthma Educators, AAFA, AOA/CCME-AOA, NACNS, NAPNAP, NASW, accredited academic institutions, and State Boards of Nursing. CEUs must be earned during your five-year term — credits earned after expiration are not accepted.

Option 2: Retake and Pass the AE-C Examination

AE-C holders may instead retake and pass the AE-C Examination. This must be done during the final year of the five-year credential period; a new five-year term begins on the date you pass.

Option 3: Earn a Different NBRC Credential

Passing an NBRC credentialing examination you have not previously completed extends all of your NBRC credentials by five years from the date the new credential is earned, aligning every expiration date.

Lapse penalties: If your credential expires, you may no longer use the AE-C designation. Within six months of expiration you can still enter CEUs online and pay a $250 reinstatement fee; beyond six months you must reapply and retest under the admission rules then in effect.
