According to the current EU regulation it is mandatory for all x-ray screeners to be evaluated on a regular basis to ensure high competency when working with x-ray imagery. The X-Ray Competency Assessment Test (X-Ray CAT) provides a reliable and valid certification tool fully in compliance with the EU regulation 185/2010.

Competency assessment test for x-ray screeners

CERTIFICATION

FULLY COMPLIANT TO EU REGULATIONS

The X-Ray CAT was developed accord-ing to the EU regulation as well as the ECAC Handbook and can be used for official certification of x-ray screeners.

Developed by former x-ray operators and psychologists in close collaboration with aviation security experts, it meets the claim of both being in step with op-erational experience and fulfilling high statistical quality standards.

HIGHLY RELIABLE AND VALID TEST RESULTS

The images for the tests are hand-picked based on scientific criteria and go through a series of pre-tests in order to adhere to the highest standards.

This results in excellent reliability coef-ficients with a high Cronbach’s Alpha (>.90) and split-half values which guar-antee highly reliable test results (.80 is considered as the minimum standard).

SIMPLE AND STANDARDIZED TEST PROCEDURE

The examinees are guided through the test by clear instructions and with a series of integrated exercises. This pro-vides a fair and objective test environ-ment with comparable results. Thanks to the feature of immediate feedback, the administrator spots directly after completion if the examinee passed the test.

TOOL FOR SUPERVISION AND BENCHMARKING

Additionally to its function as a certifica-tion test tool, X-Ray CAT offers the op-tion to use it as a tool to determine indi-vidual weaknesses of the security officers. This performance benchmark based on the X-Ray CAT test may also be established nationally or even inter-nationally to discover potentials for im-provement on a larger scope.

REGULAR UPDATES AND IMPROVEMENTS

The tests are validated and updated regularly to adhere to the latest stan-dards of x-ray image quality and to com-ply with the official regulations.

BAG-TO-THREAT MERGING ALGORITHM

Our unique merging algorithm allows the software to produce a large number of images and also enables a precise and flexible control over the difficulty of the images.

REPRESENTATIVE SELECTION OF IMAGES

The tests contain a wide-ranging se-lection of representative x-ray images, whereas, by default, half of the images contain prohibited items. This is the ide-al relation for statistical purposes. Upon request the number of threat items may be changed in order to meet individual requirements.

REAL-WORLD VIEWING OPTIONS

In order to make the test as realistic as possible, we integrated all common im-age enhancement functions to provide the same viewing conditions as the se-curity officer would have at the check-point.
