CCJS 440 at the University of Maryland Global Campus is a practical study of friction ridge analysis, the skin patterns on fingers and palms that leave fingerprints.
UMGC's catalogue describes the objective as applying the skills of an entry-level fingerprint professional: assessing surfaces for viable latent prints, evaluating how to process and collect them, analysing, comparing, evaluating and verifying fingerprint evidence, and conveying findings.
Topics include processing and comparison methods, the historical and biological foundations of impressions, and legal aspects.
The prerequisite is CCJS 301 or CCJS 320, and it is one of six required courses in UMGC's Crime Scene Investigation certificate.

What CCJS 440 Covers
- Foundations: how friction ridges form and why they are considered unique and persistent.
- Surfaces and processing: choosing powders or chemical methods for porous and non-porous surfaces.
- Collection: photographing and lifting latent prints without losing detail.
- Comparison: analysing, comparing, evaluating and verifying prints.
- Legal aspects: admissibility, error and how examiners testify.
Key Concepts Explained
Levels of Detail
Examiners describe three levels of detail. Level 1 is the overall pattern (loop, whorl or arch). Level 2 is minutiae such as ridge endings and bifurcations. Level 3 covers fine features like pores and ridge edges.
ACE-V
The widely taught comparison method has four stages: Analysis, Comparison, Evaluation and Verification. The latent print is analysed first on its own, before the examiner looks at the known print, to reduce bias.
Example: A latent print from a glass shows a loop pattern with clear ridge endings in one area. During analysis, the examiner notes which areas are usable before seeing any suspect's prints. In comparison, features are checked against a known print. In evaluation, the examiner reaches a conclusion: identification, exclusion or inconclusive. A second qualified examiner then verifies it.
Matching Processing to Surface
Powders generally suit smooth, non-porous surfaces, while chemical methods are used on porous items such as paper. The order of methods matters, because some can prevent others from working.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Pattern classification | Level 1 detail | Identify the core, deltas and pattern type for each print |
| Comparison exercise | ACE-V | Document each stage separately, with marked features |
| Processing plan | Surfaces and methods | Choose methods in a sensible order and justify them |
| Legal discussion | Admissibility and error | Use a real case and explain what went wrong or right |
Legal Aspects and Error
The course includes legal aspects, which usually means discussing how fingerprint evidence is challenged. Well-known misidentification cases show how bias and pressure can affect examiners, and they are a common basis for discussion posts.
Strong answers avoid claiming that fingerprint evidence is infallible. Explain how blind analysis, verification and documentation reduce error, and how an examiner should state a conclusion in court.
Biological and Historical Foundations
UMGC's topics include the historical and biological foundations of impressions. Biologically, friction ridges form before birth and keep their arrangement through life unless the skin is deeply scarred, which is why they are useful for identification.
Historically, fingerprints replaced earlier body-measurement systems for identifying people, and national collections grew into today's automated search systems. Exam and discussion questions often ask why fingerprints won out and what the shift meant for policing.
Automated systems return candidate lists, not identifications. A human examiner still has to carry out the comparison and reach a conclusion, which is why the comparison skills taught in this course remain central.
Where Students Get Stuck
- Looking at the known print too early. Analyse the latent first.
- Too few marked features. Document the features that support your conclusion.
- Wrong method order. Check which processes must come first.
- Overstated certainty. Use the standard conclusion categories.
Study Tips for CCJS 440
- Practise classifying your own inked prints by pattern type.
- Learn the common minutiae names with a sketch of each.
- Make a chart of processing methods by surface type and sequence.
- Read one misidentification case and note the lessons.
Finally, treat every practice comparison as if it might be reviewed by a second examiner. Clear notes, marked images and a stated conclusion make verification possible, and verification is the last stage of ACE-V for a reason: it is how the discipline catches its own errors.
