A reflex timing device having a first switch. Engagement of the first switch causes a microcontroller to activate a second visual indicator at a random time. The micorcontroller measures the time between activation of the second visual indicator and engagement of a second switch. This measured time is compared by the microcontroller with a required benchmark reflex time, which may optionally be selected from several benchmark reflex times. A signal indicating success is provided if a subject being tested does not disengage said first switch until said second visual indicator has been activated and if the subject also engages said second switch within the required benchmark reflex time. Optionally, a signal indicated failure may be provided if these conditions have not been met.
