What is involved in a proficiency test?
The test is designed to simulate a case. You will be given some form of media and a case scenario. It is used to measure how proficient an examiner is at working a case. This does not mean the examiner is required to know everything about the specific topic but how well they deal with it. For example, a proficiency test may consist of a Linux disk, in which you are asked to look for images. You do not need to be an expert in Linux to work this case. If you can image the disk successfully, identify it is some form of Linux OS, and maybe even retrieve some images from the disk, then you have successfully passed the test. Failing would be simply look at the disk in DOS and determined there was nothing of apparent evidentiary value. The test should be worked like any other case you would receive.
