The Exam at a Glance
This is the one-page review for the Certified Group Fitness Instructor (AFAA-CGFI) credential from the Athletics and Fitness Association of America (AFAA). It covers the current CGFI certification only. It does not cover the legacy Primary Group Exercise (PGE) credential, the non-proctored Group Fitness Instructor certificate, or any ACE credential. If you are still sorting out what the credential is, start with What Is AFAA-CGFI? and then come back here for the numbers.

The question and timing figures come from the December 2025 AFAA Candidate Handbook (page 22). The handbook, the exam blueprint, and the AFAA exam-information page are the three official documents to bookmark. Everything below traces back to those sources or to the August 2025 Recertification Handbook.
Eligibility and Exam-Day Logistics
Prerequisites
- Education: a high school diploma or equivalent, completed or within 90 days of completion.
- Safety certification: current adult CPR/AED before you sit for the exam.
- Experience: the eligibility section lists no separate experience-hour, training-hour, or reference minimum.
- Course purchase: a preparation course is not required to sit the exam and does not guarantee a passing score.
For a fuller walkthrough of qualifying, see AFAA-CGFI Requirements: Eligibility, Prerequisites & How to Qualify.
Scheduling and arrival
- Scheduling requires at least 24 hours' notice.
- Bring valid government photo identification and current CPR/AED evidence.
- The exam is closed book, whether you test at a PSI center or through live remote proctoring.
- Your 180-day enrollment window is a deadline, so work backward from it when you pick a test date.
Date logistics are covered in AFAA-CGFI Exam Dates: Testing Windows, Deadlines & Scheduling.
Scoring: What 70 Really Means
The passing standard is a scaled score of 70 or higher on a 0-100 scale. A scaled score is not the same as getting 70 percent of items correct. Scaling adjusts for the difficulty of the particular form you receive, so do not plan around a magic raw percentage.
Two other facts matter for pacing and mindset:
- 20 of the 120 questions are unscored pretest items. They are mixed in and look identical to scored questions. You cannot tell which ones they are, so treat every question seriously.
- 100 questions are scored. That gives you roughly one minute per question across the 120-minute window, with no extra time budgeted for pretest items.
For a deeper explanation of scaled scoring, read AFAA-CGFI Passing Score: Exactly What You Need to Pass.
Domain Weights in One Table
The four official examination domains and their published percentages come from the 2020 practice-analysis blueprint. The blueprint retains all 59 knowledge statements and 25 tasks. These are official exam objectives, not preparation-curriculum headings.
| Domain | Weight | Content Type |
|---|---|---|
| 1. Fundamentals of Exercise Science | 27% | Knowledge statements (k1-k10) |
| 2. Class Design and Planning | 30% | Tasks A-H plus knowledge (k11-k30) |
| 3. Class Instruction and Presentation | 30% | Tasks A-I plus knowledge (k31-k46) |
| 4. Professionalism | 13% | Tasks A-H plus knowledge (k47-k59) |
Domains 2 and 3 are jointly the highest-weighted at 30% each, so 60% of the blueprint is about designing and delivering classes. Exercise science is a strong third at 27%, and professionalism is the smallest at 13%. A practice-analysis executive summary linked by AFAA is labeled 2021, while the approved blueprint scope is the 2020 practice analysis; that dating discrepancy is noted but does not change the weights above. For a full breakdown, see AFAA-CGFI Exam Domains: Complete Guide to All 4 Content Areas.
Domain 1: Fundamentals of Exercise Science (27%)
Scientific foundations (k1-k10)
This domain covers the science behind everything a group fitness instructor does. Expect scenario-style questions that apply a concept rather than ask for a bare definition.
- Body systems (k1-k2): structure, function, and integration of the nervous, muscular, and skeletal systems, plus the cardiovascular and respiratory systems.
- Kinesiology (k3): basic biomechanical terminology and how internal actions and outside forces create movement.
- Metabolism and bioenergetics (k4): exercise metabolism, nutrition basics, and basic training adaptations.
- Training concepts (k5-k6): flexibility, cardiorespiratory, core, balance, strength, plyometric, SAQ, and resistance training; plus adaptation, progression, specificity, overload, and recovery.
- Benefits (k7-k8): health benefits of exercise and the benefits of group formats such as accountability, commitment, and community.
- Special populations (k9): basic considerations for medical and orthopedic conditions, older adults, pre- and postnatal participants, and other special needs.
- Environment (k10): physiological responses to temperature, humidity, altitude, and pollution.
Note the word basic repeated through this domain. The exam tests working knowledge an instructor needs, not clinical depth. Group fitness instructors do not diagnose or treat pain or disease, and they refer those needs to health care professionals. Questions on special populations usually reward the answer that adapts the class safely or refers out, rather than the answer that plays clinician.
Domain 2: Class Design and Planning (30%)
This is tied for the heaviest domain. It tests whether you can build a safe, effective, engaging class for a diverse group. The blueprint lists eight tasks (A-H) and knowledge statements k11-k30.
Structure and objectives
- Define class objectives such as cardiorespiratory endurance, muscular strength, stability and core, flexibility, and mind-body connection.
- Know the basic class components: movement prep (warm-up), main body of the workout, and transition (cool-down).
- Know class types and formats (dance, aqua, indoor cycle, interval, resistance, flexibility) and their expected benefits.
- Apply SMART goal development and methods to improve results by adjusting frequency, intensity, time, type, or tempo.
Exercise selection, sequencing, and options
- Choose exercises suited to each class component and to a range of fitness and skill levels.
- Design combinations, choreography, and transitions that support form, safety, and flow.
- Plan modifications, progressions, and regressions in advance (k24-k25).
- Know techniques for strength and endurance, cardiovascular fitness, flexibility and mobility (static and dynamic stretching), and stability and balance.
- Plan to vary music, exercises, and intensity periodically to support engagement and retention.
Equipment, environments, and music
- Match equipment to class objectives, with safe and varied uses, space requirements, and fitness levels in mind.
- Adapt to environments: virtual, outdoors, gym, and personal studio; consider class size, small spaces, pools, and flooring types.
- Music selection covers BPM appropriate to the activity and class component, genre and demographics, and music volume/decibel guidelines.
- Know music structures: chorus, verse, 32-count phrase, radio edits, non-stop mixes, and playlists.
- Know the differences between freestyle, pre-designed, and pre-choreographed class formats (k30).
Music is a distinctive feature of this exam compared with general personal training content. Expect to reason about tempo, phrasing, and volume as part of class design.
Domain 3: Class Instruction and Presentation (30%)
The other 30% domain is about delivery: coaching, demonstration, monitoring, and adapting in real time. It has nine tasks (A-I) and knowledge statements k31-k46.
Communication and cueing
- A clear introduction covering your name, class format, duration, and equipment required sets expectations.
- Know learning styles (visual, auditory, kinesthetic) and communication strategies such as speaking clearly, eye contact, and body language awareness.
- Know verbal, nonverbal, and music-based cueing and when to use each.
- Understand how virtual instruction differs from in-person: participant visibility, generalized versus tailored feedback, and engagement techniques.
- Apply participant-centered, positive, and inclusive coaching to encourage adherence.
Monitoring and safety
- Posture and alignment: neutral spine, lordosis, and kyphosis; joint alignment and range of motion.
- Exertion signs: physical signs and symptoms of over- and under-exertion, fatigue, and dehydration.
- Intensity methods: rate of perceived exertion (RPE), talk test, monitoring devices, form checks, and pain levels; plus heart-rate response to different class components.
- Self-monitoring instruction: teach participants to gauge their own cardiovascular and musculoskeletal stress and strain.
- Variations: add or remove arm movements or jumping; push-ups on knees or toes (k45).
Domain 4: Professionalism (13%)
The smallest domain is still very testable because its questions often have one clearly safest or most ethical answer. Tasks A-H and k47-k59 cover:
- Legal and ethical practice: client confidentiality, instructor-participant relationship, music trademark/copyright, and applicable music licensing laws.
- Scope of practice: limits on nutritional, medical, and psychological advice, and proper/appropriate physical contact with participants.
- Risk management: liability insurance requirements and participant liability waivers.
- Emergencies: emergency response preparedness following established protocols and documentation requirements.
- Codes of conduct: industry guidelines such as the IDEA Code of Conduct and the AFAA Code of Conduct.
- Digital content: considerations when recording content and using social media, including proprietary content, participant agreement, music licensing, and facility considerations.
- Growth and retention: customer service and marketing strategies, including social media, to build rapport and loyalty.
- Self-management: protecting your voice, monitoring workload, and avoiding overtraining; know occupational hazards like overuse injuries, overtraining syndrome, and vocal damage.
- Inclusion: promoting inclusion and equity for a diverse population, plus professional behavior such as punctuality, attire, and language.
Key Takeaway
When a scenario involves a participant asking about an injury, a medical condition, or a supplement plan, the scope-of-practice answer is almost always to stay within your role and refer to an appropriate health care professional.
Validity and Renewal Facts
The credential is valid for two years. Per the August 2025 Recertification Handbook, renewal requires:
- 1.5 CEUs (15 contact hours), including 0.1 CEU for CPR/AED.
- Current CPR/AED and documented application.
- A $99 standard renewal fee, as listed in that handbook.
What Is Not Publicly Verified
A good cheat sheet is honest about its gaps. These items are not established by the reviewed official sources:
- Current pass rate: not verified; the 2024 statistics report has an internal percentage/count conflict.
- Standalone exam fee: not publicly verified, including any member/nonmember distinction.
- A separate exam code: none was found in the blueprint, December 2025 Candidate Handbook, or AFAA exam-information page, which identify the exam as AFAA-CGFI/CGFI.
- Salary figures: this article makes no earnings claims; for career context, see AFAA-CGFI Salary Guide, AFAA-CGFI Jobs, and Is the AFAA-CGFI Certification Worth It?.
Difficulty is a separate question from pass rates; How Hard Is the AFAA-CGFI Exam? discusses it without relying on unverified statistics.
Scheduling Domains Across Your Prep Weeks
Because Domains 2 and 3 carry 60% of the blueprint, give them the most calendar time and revisit them last. This sample sequence assumes about four weeks and fits inside the 180-day enrollment window; adjust it to your own schedule. For a broader plan, see the AFAA-CGFI Study Guide.
Domain 1: Exercise Science
- Body systems, kinesiology terms, and bioenergetics (k1-k4)
- Adaptation, progression, specificity, overload, and recovery (k6)
- Special populations and environmental conditions (k9-k10)
Domain 2: Class Design and Planning
- Warm-up, main body, and cool-down structure (k11, k16-k17)
- Modifications, progressions, and regressions for each exercise type
- Music BPM, 32-count phrasing, volume guidelines, and class formats
Domain 3: Instruction and Presentation
- Verbal, nonverbal, and music-based cueing scenarios
- RPE, talk test, and signs of over-exertion or dehydration
- Unexpected-condition responses and virtual versus in-person differences
Domain 4 plus full review
- Scope of practice, licensing, liability, and emergency documentation
- Timed mixed-domain practice sets with extra weight on Domains 2 and 3
Place Domain 4 late because its answers rely on the vocabulary and scenarios you built in the earlier domains, and its smaller weight means it responds well to a focused final pass. When you are ready for timed practice, take a full AFAA-CGFI practice test and review every missed item by domain.
