- The separate practical has 3 scenarios, a 60-day window, and a 100% passing criterion.
- Initial certification, recertification and retest fees are each $300 for IAI members or $400 for nonmembers.
What the 12 Content Areas Really Represent
The Footwear Certification (CFWE) from the International Association for Identification (IAI) leads to Certified Footwear Examiner status. When candidates search for the "CFWE exam domains," they usually expect a tidy percentage-weighted blueprint like those published for many professional exams. That is not what the issuer provides here, and it is worth understanding before you plan a single study session.
The 12 areas listed in this guide reproduce the exact subject terms in the official Scope of Certification: Terminology, Detection, Recovery, Photography, Preservation, Enhancement, Analysis, Comparison, Manufacturing processes, Documentation, Reporting, and Courtroom testimony. They are best treated as unweighted preparation topics. The count of twelve reflects the supplied headings, not an issuer-declared 12-domain exam blueprint. That means no domain can be called "the highest-weighted," no question allocations are published, and the list should not be read as exhaustive coverage of every possible exam item.
If you want a broader orientation first, see What Is CFWE Certification? and CFWE Certification. For a condensed review of the facts you will need on test day, the CFWE Cheat Sheet is a useful companion to this domain walkthrough.
How the Written Exam and Practical Fit Together
The domains are tested across two distinct components, and confusing them is one of the most common planning mistakes.
| Component | Format | Passing Criterion |
|---|---|---|
| Initial written assessment | 100 multiple-choice questions, 2 hours, closed book, Board-approved proctor | 80% |
| Initial practical | 3 scenarios, unproctored, 60-day completion window | 100%; every conclusion correct and supported by objective documentation |
| Recertification practical | 1 unproctored scenario, completed within 30 days of postmark | 100%; correct, objectively supported conclusion |
The written component rewards breadth. Multiple-choice questions can draw on terminology, procedures, recovery and photographic technique, manufacturing knowledge, and reporting and testimony practice. The practical rewards depth and discipline: you must reach the correct conclusion in every scenario and back it with objective documentation. A single unsupported or incorrect conclusion fails the criterion, so the practical effectively exercises Analysis, Comparison, Documentation and Reporting at a standard that leaves no margin.
For a candid look at how these demands translate into difficulty, read How Hard Is the CFWE Exam?. For the exact scoring threshold and what it means in practice, see the CFWE Passing Score guide.
Domains 2-6: From Detection to Enhancement
Five of the twelve areas describe the life of an impression from the moment it is found to the moment it is made visible and usable. Think of them as a connected workflow rather than five isolated subjects. Exam questions in this cluster often test whether you can choose the right action at the right point, and whether you understand what each action does to the evidence.
Domain 2: Detection
Finding impressions that are latent, faint, or on challenging surfaces.
- Lighting approaches and how angle and wavelength change what is visible
- Surface and substrate considerations that affect whether an impression is present and findable
- Systematic search practice, so absence of a find is a documented result rather than an assumption
Domain 3: Recovery
Collecting the impression or the item bearing it, using methods suited to the evidence type.
- Selecting between casting, lifting, and collecting the substrate itself
- Matching the recovery method to the impression's condition and surface
- Understanding what each method preserves and what it can lose
Domain 4: Photography
Capturing a true-to-scale, examination-quality record before anything else touches the evidence.
- Scale use, camera orientation, and consistent lighting for examination-quality images
- Overall, medium and close-up documentation of context and detail
- Why photography generally precedes any recovery attempt
Domain 5: Preservation
Keeping evidence in a condition that protects its value from scene to laboratory.
- Packaging and handling choices that avoid damage or contamination
- Protecting the integrity of impressions and recovered items
- The link between preservation practice and defensible chain of custody
Domain 6: Enhancement
Improving the visibility of an impression without compromising its evidentiary value.
- Physical, chemical and imaging approaches to bringing out detail
- Sequencing enhancement so a more destructive step never forecloses a less destructive one
- Documenting each enhancement step so the process can be reviewed
A recurring theme across this cluster is order of operations. Questions frequently hinge on what should happen first and why. Photograph before you recover, use non-destructive techniques before destructive ones, and document before and after every step that changes the evidence. If you internalize that logic, many scenario-style questions become a matter of reasoning rather than recall.
Domains 7-9: Analysis, Comparison and Manufacturing
This cluster is the intellectual core of footwear examination. It is where an examiner moves from "an impression exists" to "what can be concluded from it." It is also where the practical's 100% criterion bites hardest.
Domain 7: Analysis
Evaluating the questioned impression and the known footwear independently before any side-by-side work.
- Assessing the quality, clarity and limitations of the impression itself
- Identifying class characteristics such as design, size and general wear
- Recognizing individualizing features such as randomly acquired characteristics
Domain 8: Comparison
Systematically comparing the questioned impression with known footwear and reaching a supportable conclusion.
- Methodical, repeatable comparison of class and acquired characteristics
- Understanding the conclusion scale, including the SWGTREAD 2013 Range of Conclusions standard that the announced reading list retains
- Tying every conclusion to observable, documented features rather than impression or intuition
Domain 9: Manufacturing processes
Knowing how footwear is made, because manufacturing determines which features are class and which can be individual.
- How outsoles and tread designs are produced, and what that implies for shared and distinguishing features
- Why molding and cutting methods influence how reliable a given feature is for discrimination
- The relationship between production variation and the weight an examiner can give a feature
Because the practical demands a correct conclusion supported by objective documentation in every scenario, treat this cluster as the place where precision matters most. Our CFWE Pass Rate discussion explains why we avoid quoting numbers the issuer has not published, and what a careful candidate can infer instead.
Domains 10-12: Documentation, Reporting and Courtroom Testimony
The last three areas address what happens after the examination work is done. Technical accuracy is necessary but not sufficient: the work must be recorded, communicated, and defended.
Domain 10: Documentation
Creating contemporaneous records that let another qualified examiner understand and evaluate what you did.
- Notes, images and measurements sufficient to support each conclusion
- Recording observations, not just results, so the reasoning is reconstructable
- The direct link to the practical's requirement for objective documentation
Domain 11: Reporting
Communicating findings clearly, using accepted terminology and appropriately qualified conclusions.
- Stating conclusions in language consistent with recognized standards
- Avoiding overstatement beyond what the evidence supports
- Making reports intelligible to non-specialists without sacrificing accuracy
Domain 12: Courtroom testimony
Presenting and defending your methods and conclusions under examination.
- Explaining methodology and limitations plainly and honestly
- Staying within the scope of your expertise and the evidence
- Understanding how documentation and reporting quality shape cross-examination
These three domains reward candidates who have actually written reports and testified, but they are also learnable by anyone who reads the reference standards closely. Pay special attention to how conclusions are worded, because the written exam can test whether you recognize an appropriately qualified statement versus an overreaching one.
Domain 1: Terminology as the Foundation
Terminology is listed first for a reason. Every other domain assumes you can use the discipline's vocabulary precisely: the difference between class and acquired characteristics, between an impression and the footwear that made it, between a recovered image and an enhanced one. Imprecise vocabulary produces imprecise conclusions, and on a closed-book exam it produces missed questions that had nothing to do with your technical skill.
Build a personal glossary early and revisit it throughout your preparation. Because the exam is closed book, definitions must be retrievable from memory. If you are newer to the field, What Is CFWE? and What Does CFWE Stand For? help you separate this credential from the other certifications that share the same four letters, so the terminology you study is the right terminology.
The Reading List and the January 1, 2027 Transition
One of the most practically important facts for a 2026 candidate is the timing of the reading-list change. Preparation done before January 1, 2027 uses the current references:
- William J. Bodziak, Forensic Footwear Evidence, first edition, 2017
- The IAI Recommended Course of Study for Footwear and Tire Track Examiners, 2006
- The designated SWGTREAD documents
Effective January 1, 2027, the announced list adds ANSI/ASB 021 (2019), 049 (2020), 050 (2021), 052 (2022), 126 (2020) and 095 (2020). These replace designated older guides and the IAI course of study, while Bodziak 2017 and the SWGTREAD 2013 Range of Conclusions standard are retained. This future list is announced, not yet in effect, so do not study from it as though it already governs a 2026 exam.
Key Takeaway
Check the issuer's footwear page for the current change notice before you commit to a reading plan. If your testing window straddles the transition date, build your study around the sources that appear on both lists first, namely Bodziak 2017 and the SWGTREAD 2013 Range of Conclusions standard.
Note also that the paid IAI course-of-study text is not something this guide reproduces, and we have not invented topics from it. The 12 domain names above come directly from the Scope of Certification. For hands-on preparation resources, see our CFWE Study Guide and CFWE Training overview.
Eligibility, Fees and Why They Shape Your Prep
Domain knowledge only matters once you are eligible to sit the exam, and the 2026 requirements are specific. Eligibility requires employment performing the section 8.3 footwear tasks and successful completion of a documented training program covering that scope, with training records submitted for review through eCert. You also need two recommendation letters, two additional references from different people, and a signed certification agreement. Training acceptance and recency are governed by sections 7.1.3.2 and 8.9, including chair discretion for older training.
Do not rely on older summaries that describe degree-plus-experience pathways or fixed-hour or fixed-year thresholds; those do not reflect the current C27 text. Our CFWE Requirements article walks through qualifying in detail.
| Application Type | IAI Member | Nonmember |
|---|---|---|
| Initial certification | $300 | $400 |
| Recertification | $300 | $400 |
| Retest | $300 | $400 |
Division membership alone does not qualify you for the member rate. Because a retest carries its own fee and a waiting period (6 months after an initial attempt, 3 months for recertification retesting), efficient preparation across all twelve domains has real financial and scheduling value. See the CFWE Certification Cost breakdown for the full picture, and CFWE Exam Dates for scheduling considerations.
Sequencing the 12 Areas Across Your Prep Weeks
Since the domains are unweighted, sequence them by dependency rather than by supposed importance. Vocabulary first, then the evidence workflow, then the examination reasoning, then communication. The timeline below is one reasonable ordering; adjust the pacing to your casework and training background.
Terminology and Manufacturing
- Build your glossary: class versus acquired characteristics, impression versus footwear
- Read the manufacturing material in Bodziak 2017 early, since it underpins later comparison questions
Detection, Photography and Recovery
- Rehearse the order of operations: detect, photograph, then recover
- Review lighting, scale and method-selection logic
Preservation and Enhancement
- Study packaging, handling and non-destructive-first sequencing
- Practice documenting each enhancement step
Analysis and Comparison
- Work through the SWGTREAD 2013 Range of Conclusions standard until you can apply it from memory
- Practice supporting every conclusion with observable features
Documentation, Reporting and Testimony; Practical Rehearsal
- Draft sample reports with properly qualified conclusions
- Run mock practical scenarios aimed at the 100% standard
Use practice questions throughout rather than saving them for the end. Our CFWE practice tests let you drill the written format, and working through them regularly shows which domains need more attention. If you want a fuller plan, the CFWE Study Guide expands on pacing.
How the Domains Resurface at Recertification
The 12 areas do not stop mattering once you are certified. Certification is valid for up to 5 years, and renewal requires 80 professional-development credits earned within the preceding 5 years, an application and fee, and one unproctored practical scenario completed within 30 days of postmark. That scenario again requires a correct, objectively supported conclusion with 100% required.
The IAI's Footwear Approved Training Courses list (September 11, 2026) identifies courses approved for recertification credit. Those courses may also supplement a documented initial training program, but the list limits them to 75% of the required recertification credits and does not substitute for the initial training requirement. Course approval is not an endorsement of any provider or product. Choosing recertification training that deepens your weakest domains is a sensible way to keep your skills current rather than simply accumulating hours.

Frequently Asked Questions
No weights are published. The 12 areas reproduce the subject terms in the IAI Scope of Certification as unweighted preparation topics, so you cannot identify a highest-weighted domain or assume particular question allocations. Prepare all twelve.
The initial written assessment is 100 multiple-choice questions in 2 hours, closed book, administered with a Board-approved proctor. You need 80% to pass. The separate practical is scored on a 100% criterion.
The practical consists of 3 unproctored scenarios with a 60-day completion window. Every conclusion must be correct and supported by objective documentation. The written-exam description does not cover the practical, which is a separate requirement.
Before January 1, 2027, use Bodziak's Forensic Footwear Evidence (first edition, 2017), the IAI Recommended Course of Study (2006), and the designated SWGTREAD documents. The announced ANSI/ASB additions take effect January 1, 2027, so check the issuer's footwear page for the current notice.
Initial certification, recertification and retest applications are each $300 for IAI members or $400 for nonmembers. Division membership alone does not earn the member rate. Retesting carries a 6-month waiting period after an initial attempt and 3 months for recertification retesting.
