Kedlin Screening International (KSI) delivers a scientifically based search solution to give you the edge to achieve better, faster, and more accurate threat detection screening in any industry that requires a high level of screening competency.

Our solution was developed using billions of trials and the world’s most extensive research dataset on human performance relating to aviation search and from hands-on experiences with professional aviation security screeners.

Using this rich data, KSI created our flagship tool called XRAY Screener to accurately predict aviation security search performance based on accuracy and response trials.

KSI’s XRAY Screener is a cost-effective, tablet-based technology that identifies an individual’s visual detection capabilities. KSI compares individual performance to performance of more than 12 million people to understand each person’s strengths and weaknesses. This individualized approach opens the door for directed and specific training interventions.

KSI’s XRAY Screener delivers you the edge to:

  • Assess new recruits’ visual search capabilities pre-hire
  • Select top capability performers
  • Reduce costs associated with hiring the wrong people
  • Increase efficiency by identifying top performers in your current workforce
  • Deliver targeted training to lower end performers
