This document presents a plan to develop and evaluate an X-ray Image Screener Selection Test (XISST). The XISST will be a computer-based job sample selection test, which will predict the effectiveness of X-ray screeners. The selection test, which will involve searching for common objects in X-ray images, will be tested for usability before being fielded. The field test will take place at two airports. Human Factors Engineers will administer the XISST to at least 50 security screeners from these airports who have at least 2 months of Threat Image Projection (TIP) experience. The goal of this evaluation will be to determine the reliability of the XISST and its validity as a predictor of screener TIP performance.
