- AVFA stands for Audio-Video Forensic Analyst, a stand-alone certification from ETA International.
- No CETa prerequisite or hands-on test is required - only a 100-question theory exam.
- You need 75% correct in two hours to pass, at a base exam fee of US$105.
- Seven domains cover file structure, metadata, tamper detection, enhancement, and forensic fundamentals.
What AVFA Actually Means
AVFA stands for Audio-Video Forensic Analyst, a certification developed and administered by ETA International (Electronics Technicians Association). It is a stand-alone credential, meaning candidates do not need to hold ETA's Associate Certified Electronics Technician (CETa) certification before sitting for it. AVFA validates that a technician or analyst understands how digital audio and video files are built, how they can be authenticated, and how they should be enhanced and reported on for use in investigative or legal contexts.
It's worth pausing on this because the acronym "AVFA" is used elsewhere in the certification world for unrelated credentials. This site, and this article, are exclusively about ETA International's Audio-Video Forensic Analyst designation - the exam facts, fees, and domain structure described here apply only to that credential. If you've seen different numbers or requirements attached to "AVFA" somewhere else, they almost certainly refer to a different program.
Who Issues the AVFA Credential
ETA International administers the AVFA exam through ETA Certification Administrators, using the Trapeza online testing platform or paper-based examinations at approved test sites. Candidates who cannot travel to a physical site can use remote proctoring through ExamRoom.AI instead. This flexibility matters for analysts working in law enforcement, media forensics labs, or private investigative firms who may be based far from a traditional test center.

Exam Format, Fees, and Registration
The AVFA exam is entirely theory-based: 100 questions, a two-hour time limit, and a required passing score of 75%. There is no hands-on skills assessment component to this certification - everything is assessed through the written exam.
- Base exam fee: US$105
- Remote proctoring add-on: US$16 for the two-hour exam via ExamRoom.AI
- Format: 100 multiple-choice-style theory questions
- Time allowed: Two hours
- Passing score: 75%
- Prerequisite: None - CETa is not required for this stand-alone pathway
On test day, bring photo identification, since ETA testing rules require it for admission. Scratch paper and a non-programmable calculator are permitted during the exam, but personal notes, phones, and programmable devices are not.

Key Takeaway
Because there's no hands-on component, every point of preparation should go toward the written exam's 100 questions - practice testing under a two-hour clock is more valuable here than physical skills rehearsal.

The Seven AVFA Domains
ETA International's 2022 AVFA competency requirements organize the exam content into seven domains. Each one represents a distinct body of knowledge you're expected to bring into the testing room.
Domain 1: General Understanding of Audio and Video File Structure and Compression
Covers how digital audio and video data is organized and compressed at a fundamental level.
- Container formats versus codecs
- Lossy vs. lossless compression trade-offs
- How compression artifacts appear in output files
Domain 2: Metadata and Header Structure of Digital Audio and Video Files
Focuses on the embedded information inside a file that reveals its origin and history.
- Header fields and what they disclose about a recording device
- Metadata as evidence of editing or file transfer
- Reading metadata without altering the original file
Domain 3: Authentication and Application of Tamper Detection with Digital Audio and Video Files
Tests your ability to determine whether a file has been altered since its original capture.
- Signs of splicing, re-encoding, or frame manipulation
- Chain-of-custody considerations tied to authentication
- Tools and methods used to flag tampering
Domain 4: Enhancement Methodologies of Digital Audio and Video Files
Covers techniques for improving clarity of evidence without misrepresenting content.
- Noise reduction and filtering approaches for audio
- Image sharpening, stabilization, and frame interpolation for video
- Where enhancement ends and fabrication risk begins
Domain 5: Audio Forensic Fundamentals
Core principles of analyzing recorded audio for forensic purposes.
- Speaker and voice analysis fundamentals
- Recognizing recording anomalies and background artifacts
- Audio evidence handling standards
Domain 6: Video-Image Forensic Fundamentals
Parallel foundation for visual evidence analysis.
- Frame-by-frame examination techniques
- Lighting, shadow, and geometry consistency checks
- Common video capture and playback artifacts
Domain 7: Industry Requirement, Best Practices, Report Writing, and Relevant Federal Code
Ties technical skill to professional and legal expectations.
- Writing findings clearly for non-technical audiences (courts, attorneys)
- Following recognized best-practice frameworks
- Awareness of relevant federal code governing evidence handling

Who Earns AVFA and Why
AVFA is built for people who already touch digital audio and video evidence in some professional capacity - forensic lab technicians, law enforcement personnel handling body-camera or surveillance footage, media authentication specialists, and private investigators who need a recognized credential behind their analysis. Because the exam is theory-only and doesn't require prior CETa certification, it's accessible to analysts coming from adjacent fields (IT, digital forensics, video production) who want a credential specific to authentication and enhancement work rather than general electronics competency.
Employers value AVFA because it signals a candidate understands not just how to use enhancement software, but why certain enhancement choices are defensible in a legal setting - which is exactly what Domain 7 tests.

Keeping AVFA Current After You Pass
Passing the exam is not the end of the AVFA lifecycle. Certification is valid for four years, but it requires annual upkeep to stay active. Each year, certificants must submit a maintenance form along with either 10 hours of continuing education (40 hours across the full four-year cycle) or employer verification of relevant work activity, plus a maintenance fee of US$25 per year (US$100 across four years).
This maintenance structure is one reason the full cost of AVFA is more than just the exam fee - plan your budget across the whole cycle, not just registration day. See AVFA Certification Cost 2026: Complete Pricing Breakdown for the complete math.
A Domain-Aligned Way to Prepare
Because AVFA is a single two-hour, 100-question exam with no hands-on component, your preparation time is best spent cycling through the seven domains in blocks, then testing yourself under timed conditions to simulate the real exam pace (roughly 1.2 minutes per question).
File Fundamentals
- Domain 1: compression formats and codecs
- Domain 2: metadata and header structures
Authentication and Enhancement
- Domain 3: tamper detection indicators
- Domain 4: enhancement methods and their limits
Forensic Fundamentals
- Domain 5: audio forensic analysis basics
- Domain 6: video-image forensic techniques
Standards, Reporting, and Timed Practice
- Domain 7: report writing and federal code awareness
- Full-length timed practice runs at the 75% passing bar
This pacing gives every domain dedicated attention while leaving room to revisit weaker areas before test day. For a more detailed week-by-week study plan with recommended resources, see AVFA Study Guide 2026: How to Pass on Your First Attempt. If you want a realistic sense of difficulty before committing to a timeline, How Hard Is the AVFA Exam? Complete Difficulty Guide 2026 and AVFA Pass Rate 2026: What the Data Shows are useful companion reads. You can also run full-length timed practice exams on our AVFA practice test platform to get comfortable with the two-hour format before your official attempt.
Whichever schedule you follow, treat each domain as a distinct study unit rather than one undifferentiated pile of "AV forensics knowledge" - the exam itself is structured that way, and your review should mirror it. Running a few timed sets through the practice platform after each domain block will tell you quickly whether you're ready to move on or need another pass.
