- The AVFA theory exam has 100 questions, a two-hour limit, and a 75% passing score.
- Stand-alone exam fee is US$105; remote proctoring through ExamRoom.AI adds US$16.
- There are exactly seven ETA-defined domains covering file structure through federal code compliance.
- No hands-on skills test or CETa prerequisite is required for the stand-alone AVFA pathway.
Exam Snapshot: The Numbers You Must Memorize
Before you touch a single practice question, lock in the administrative facts of the Audio-Video Forensic Analyst (AVFA) exam. These numbers get tested indirectly - through scheduling decisions, budget planning, and how you pace yourself on exam day - and they are the most commonly misremembered details among candidates who mix up AVFA with unrelated credentials that happen to share the acronym.
- Certifying body: ETA International, administered through ETA Certification Administrators.
- Delivery format: Trapeza online testing or paper examinations at approved test sites, or remote proctoring via ExamRoom.AI.
- Question count: 100 questions on the theory exam.
- Time limit: two hours.
- Passing score: 75%.
- Base exam fee: US$105.
- Remote proctoring add-on: US$16 for the two-hour session.
- Hands-on component: none required for the stand-alone pathway.
- CETa prerequisite: not required to sit for AVFA as a stand-alone certification.
For a deeper walkthrough of how these numbers translate into a study calendar, see the AVFA Study Guide 2026: How to Pass on Your First Attempt. If you want the exact scoring math behind that 75% threshold, the AVFA Passing Score 2026 breakdown explains it question-by-question.
Domain-by-Domain Cheat Sheet
ETA's 2022 AVFA competency requirements define seven domains. This section is the fastest way to refresh what each one actually covers the night before your exam. Treat it as a recall trigger, not a first-time introduction - pair it with the full AVFA Exam Domains 2026: Complete Guide to All 7 Content Areas if any domain feels unfamiliar.
Domain 1: General Understanding of Audio and Video File Structure and Compression
Core file architecture and how compression algorithms alter data streams.
- Lossy vs. lossless compression behavior and artifacts
- Container formats vs. codecs - know the difference cold
- How compression choices affect forensic recoverability
Domain 2: Metadata and Header Structure of Digital Audio and Video Files
Reading and interpreting embedded file information that establishes provenance.
- Header fields that reveal recording device or software origin
- Metadata that can be altered vs. metadata that is harder to fake
- Chain-of-custody implications of metadata discrepancies
Domain 3: Authentication and Application of Tamper Detection with Digital Audio and Video Files
Distinguishing an original, unaltered recording from one that has been edited or manipulated.
- Signs of splicing, re-encoding, or frame insertion
- Error level analysis concepts applied to video frames
- Documenting authentication findings defensibly
Domain 4: Enhancement Methodologies of Digital Audio and Video Files
Techniques used to improve clarity without compromising evidentiary integrity.
- Noise reduction and filtering appropriate to forensic use
- Image stabilization and de-interlacing basics
- Where enhancement crosses the line into alteration
Domain 5: Audio Forensic Fundamentals
Foundational principles specific to audio evidence handling and analysis.
- Sample rate, bit depth, and their forensic significance
- Speaker identification limitations and proper framing of findings
- Recognizing recording environment artifacts
Domain 6: Video-Image Forensic Fundamentals
Foundational principles specific to visual evidence.
- Resolution, frame rate, and aspect ratio considerations
- Lens distortion and camera artifact recognition
- Comparing still images extracted from video sources
Domain 7: Industry Requirement, Best Practices, Report Writing, and Relevant Federal Code
The professional and legal framework surrounding forensic AV work.
- Report structure that withstands cross-examination
- Best-practice standards referenced by working examiners
- Federal code awareness relevant to evidence handling
Key Takeaway
Domains 3 and 7 tend to trip up candidates who focus too heavily on technical file structure - don't neglect report-writing standards and tamper-detection reasoning, since they carry equal weight on the same 100-question exam.
Registration & Test-Day Logistics
Because AVFA is delivered through ETA Certification Administrators, your registration path and test-day rules differ from other proctoring systems you may have used before. Confirm these before scheduling:
- Photo identification is required at check-in, regardless of delivery method.
- Scratch paper and a non-programmable calculator are permitted under ETA testing rules - bring your own or confirm one will be provided.
- Test sites use Trapeza online testing or paper-based administration; remote candidates use ExamRoom.AI for proctoring.
- Total cost planning: budget US$105 for the exam itself, plus US$16 if you choose remote proctoring for the two-hour session.
A full cost breakdown, including how remote proctoring fees stack against in-person testing, lives in the AVFA Certification Cost 2026: Complete Pricing Breakdown article. If you're still confirming whether you meet eligibility to register at all, check AVFA Requirements 2026: Eligibility, Prerequisites & How to Qualify - remember, the stand-alone AVFA pathway does not require CETa certification first.
Certification Maintenance Facts
Passing the exam is not the end of the AVFA lifecycle. ETA International certification requires ongoing upkeep, and forgetting these mechanics is a common reason credentials lapse unnecessarily.
- Certification period: four years total, with annual maintenance required each year within that cycle.
- Continuing education: 10 hours per year, or 40 hours over the full four-year cycle - alternatively, employer verification of relevant work activity can satisfy this requirement.
- Maintenance fee: US$25 per year, or US$100 across the four-year cycle.
- Paperwork: a maintenance form must be submitted alongside proof of CE hours or employer verification.
Key Takeaway
Set a recurring annual reminder tied to your certification anniversary date - the US$25 yearly fee and 10-hour CE requirement are easy to satisfy if tracked continuously, but expensive to catch up on if ignored for years.
Final-Week Review Plan
In the last stretch before your test date, resist the urge to start new material. Instead, cycle through the seven domains in a way that matches how the exam actually samples content - evenly, without heavier weighting toward any single area based on public ETA documentation.
File Structure & Metadata Review
- Re-drill Domain 1 compression concepts and Domain 2 metadata fields
- Practice identifying container vs. codec questions quickly
Authentication & Enhancement
- Work through Domain 3 tamper-detection scenarios
- Review Domain 4 enhancement boundaries - where does help become harm?
Audio and Video Fundamentals
- Alternate Domain 5 and Domain 6 flashcards in short bursts
- Focus on terminology you keep second-guessing
Reporting & Federal Code
- Review Domain 7 report structure checklists
- Skim any referenced federal code summaries one more time
Full Simulation
- Take a timed, 100-question practice run under the two-hour limit
- Review every missed item and trace it back to its domain
If your practice scores aren't consistently clearing 75%, don't panic - but do go back to whichever domain box above felt weakest and revisit the corresponding section of the exam domains guide.

No. The stand-alone AVFA pathway does not require Associate Certified Electronics Technician (CETa) certification as a prerequisite.
Maintenance requires 10 CE hours per year (or employer verification) plus a US$25 annual fee submitted with a maintenance form. Skipping this puts your four-year certification status at risk.
Yes. Remote proctoring is available through ExamRoom.AI for an additional US$16 on top of the standard US$105 exam fee, covering the full two-hour session.
There's no published weighting favoring one domain over another, so prioritize whichever of the seven domains - from file structure through report writing - feels weakest on your practice results rather than guessing based on assumed emphasis.
