The examination method of analysis, comparison, evaluation (ACE) and verification (V) has a history of progression. ACE-V is the examination method described in the Scientific Working Group for Friction Ridge Analysis, Study, and Technology (SWGFAST) documents. ACE is a simple explanation of the phases involved in perception and decisionmaking. ACE gives the expert specific phases of examination that can be used to document the perception, information gathering, comparison, and decision-making that takes place during an examination of prints. Scientific method is often described as observation, hypothesis formulation, experimentation, data analysis, and conclusion. ACE is one description of a method of comparing print details, forming a hypothesis about the source, experimenting to determine whether there is agreement or disagreement, analyzing the sufficiency of agreement or disagreement, rendering an evaluation, and retesting to determine whether the conclusion can be repeated. Describing information-gathering and decision-making is difficult. ACE is a structured approach to gathering information about the details in prints. ACE is not a linear method in which analysis is conducted once, comparison is conducted once, and then a decision is made once in the evaluation. ACE can and does recur during informationgathering and decision-making. However, the three phases of ACE need to be discussed independently. The analysis and comparison must be conducted so that the comparative measurements and sequences can be accurately determined to reach a valid evaluation. The purpose of the ACE-V method is to give more structure and objectivity to the exercise of print comparison, combining the factors required for a sound scientific practice. The ACE-V examination method is composed of the following steps: 1. Analysis The examiner assesses the unknown print to determine whether or not it is suitable for comparison. This involves the preliminary assessment of a number of factors like the surface material or, the substance of the print itself. 2. Comparison The investigator analyses characteristic attributes of the fingerprints and identifies conformities between the found and the known latent prints. 3. Evaluation The examiner answers a few questions: – are there any conformities between the revealed print and the known ones? – is there a sufficient number of minutiae to identify the unique correlation? There are only four possible conclusions for the examiner: 1. The latent a. identified b. not identified c. Inconclusive print or or is individualized excluded 4. Verified If an identification is made, the conclusion must be verified by peer review of another qualified fingerprint examiner. This ensures the proper application of the objective scientific method and confirms the results of the first examiner.
