Disclosed herein is a system for determining a subject's stress condition. The system includes a stress test unit configured for: receiving features defining the subject and physiological signals sensed from the subject when performing a relaxation and a stressful test task; extracting normalization parameters from the physiological signals; and identifying stress-responsive physiological features. The system also includes a storage unit configured for: storing a plurality of stress models; and storing the subject's features, normalization parameters, and the stress-responsive physiological features. The system also includes a stress detection unit configured for: selecting a stress model from the plurality of stress models based on the subject's features and the stress responsive physiological features; estimating a specific stress condition based on the stress model, stored subject's features, normalization parameters, and physiological signals that apply to the selected stress model; and providing a stress value representative of the subject's stress condition.
