X-RAY ORT

The X-Ray ORT was developed to provide a fair and comparable assessment method to reliably measure the visual abilities of an applicant.

SCIENTIFICALLY PROVEN BENEFITS

Human factors are key issues in X-ray screening. The most expensive X-ray machine is of little value if the security officer who operates it does not have the necessary aptitude and ability to interpret X-ray imagery.

Various scientific studies have shown that there are substantial individual differences in visual abilities such as mental rotation, figure ground segregation and visual search abilities which are crucial in X-ray screening.

HIGHLY ECONOMICAL AND EFFICIENT

Employees with distinctive visual abilities can learn faster and generally achieve a 20% higher level of threat detection performance in certification tests compared to X-ray operators hired without a previous pre-employment assessment using the X-Ray ORT.

Choosing the right person thus helps to minimize training costs while at the same time increasing security and efficiency at the checkpoint.

NO PREVIOUS KNOWLEDGE REQUIRED

The X-Ray ORT is a fast, easy-to-use and reliable tool in the employment procedure of potential X-ray operators

The X-Ray ORT is designed for people with no previous knowledge of how items are displayed on an X-ray machine. The test therefore only contains grayscale images and only shows guns and knives as there need to be commonly known items.

LEVEL OF DIFFICULTY SYSTEMATICALLY VARIED

The items selected for this test systematically vary in the level of difficulty, based on bag complexity, superposition and object rotation. These are the image-based factors that highly influence threat detection performance.

HIGH RELIABILITY AND VALIDITY

The images for the test were created and pre-validated by security experts and psychologists. Therefore, the X-Ray ORT features excellent reliability coefficients with both Cronbach’s alpha and split-half values above .90 (.80 is considered as the minimum standard)

WIDE RANGE OF APPLICATIONS

The X-Ray ORT can be applied wherever X-ray machines are used for security reasons, that is at airports, prisons, nuclear power plants, courts, military, event locations, etc.

FAQ

1. What does the X-Ray ORT measure?
  • The X-Ray ORT measures the ability to cope with image-based factors, such as mental rotation, figure-ground segregation and visual search which are crucial in x-ray screening.
2. How long does it take to complete the X-Ray ORT?
  • The test takes about 35 to 45 minutes.
3. Why is the X-Ray ORT only in black and white?
  • Because job applicants do not yet know what the different colors mean.
