Welcome to the Self-Evaluation section of the Extended Feature Set Training Tool (EFS-TT). The purpose of this part of the EFS-TT is to allow you to test your knowledge of marking up latent fingerprint searches using EFS features.

This self-evaluation exercise is designed to be completed in less than thirty minutes. It is composed of six types of questions created to cover key parts of the EFS standard. The first section addresses the selection of Search Profiles.

EFS Profiles define groups of features to be used for different levels of examiner effort for AFIS searches. The EFS Profiles allow a range of tradeoffs between examiner time and search accuracy as it relates to the quality and quantity of the latent print.

The profiles in the EFS include:

EFS Profile 0 is the Image-Only Profile. There is no examiner markup.
EFS Profile 1 is the Minimal Markup Profile. There is a low level of examiner markup to improve the accuracy of image-only matching, e.g., separating the print from adjacent pattern data, separating multiple impressions, or providing orientation data.
EFS Profile 2 is the Quick Minutiae Search Profile. This search profile adds minutiae to the Minimal Markup Profile. In terms of examiner effort, it is roughly equivalent to most current manual markups.
EFS Profile 3 is the Detailed Markup Profile. This search profile includes features that can be used to increase search accuracy in systems that implement this optional profile. These require an additional level of examiner effort.

From the dropdown menu above the canvas, select the profile that you think makes most efficient use of examiner effort . the one providing feature information that is consistent with the latent image quality and your organization's accuracy tradeoff policies. For these exercises, assume that you have a large workload and are attempting to maximize the total number of identity decisions in the time available.

For each of the four possibilities, display the line only if it applies:

# correct marking
# incorrect marking
# false positive
# missed core

So if there’s a false positive and a correct, show:
1 correct
1 false positive

Correct	Yes, within answer’s radius of uncertainty (if one exists; else 6 pixels)	Yes, within ±10 degrees
Incorrect Direction	Yes, within answer’s radius of uncertainty (if one exists; else 6 pixels)	No
False Positive	No answer near user response	n/a
Missed	No user response near answer	n/a
