RS&A comparison exercises are designed to help grow or enhance the comparison ability of Latent Print Examiners by providing them with the much needed time “under the glass”. Frequently during training it is difficult to provide enough comparison exercises for a trainee to work on in order to help enhance their skillset. Thus begins the arduous task of making comparison exercises which can take your most senior examiners away from the bench. At the end of training these tests are typically lost or destroyed which causes the examiner to repeat this cycle all over again for the next trainee. This ends up costing the agency much more in the long run than just simply purchasing the desired comparison exercises.
If your laboratory is interested in testing the laboratory quality system then please refer to our Proficiency Tests.
If your laboratory is interested in testing an individual, please refer to our Competency Testing.
These exercises are built to closely mimic daily casework. Each comparison exercise contains a written scenario, supporting items of evidence, answer sheet, and a sealed answer key.
- Latent Print Comparison
Contains a minimum of 10 latent prints and 4 known print cards. The known prints can include fingers, tips, or palms.
- Tenprint Comparison
Contains pattern recognition, AFIS side by side comparisons, known to known comparisons, as well as, other tenprint examiner comparison exercises.
- Footwear Comparison
Contains a minimum of 6 question impressions and 4 known impressions.
- Tire Track Comparison
Contains a minimum of 3 question impressions, photographs of known tire sections, and fully rolled known standards.
Each latent to known comparison exercise contains between 20-50 latent prints and between 4-11 known exemplars.
- These exercises vary in processing, location, orientation, difficulty, as well as, how the known prints are captured.
- These tests can be purchased individually or sold in sets (100 and 200 series) to give you the flexibility you need.
- Comparisons increases in difficulty as you progress through the exercise numbers within each set.
It is understood that the best preparation for casework is training and performance through a repetition of comparison exercises.
