TEST AND EVALUATION PLAN OF COMPUTER-BASED TRAINING FOR THE CTX 5000 EXPLOSIVES DETECTION SYSTEM

This test and evaluation plan evaluates the effectiveness of computer-based training (CBT) as an element of a Screener Proficiency Evaluation and Reporting System (SPEARS) for checked baggage screening with the CTX 5000. The CTX 5000 combines computed tomography imaging and automated detection of explosives. Alarm resolution with this complex system requires that screeners learn to skillfully discriminate system false alarms from system-identified true threats. Testing is designed to determine the effectiveness of the CBT to meet the critical operational and technical issues described in this plan. The testing will be conducted at airports where the CTX 5000 system is currently located.
