An athletic performance measurement system determines the reaction time, performance time and response time for an athlete to perform an event. A timing processor is in communication with two spaced-apart switches and when the athlete activates the first switch, it sets in motion a system for randomly activating a transducer that alerts the athlete to start the test. The athlete manipulates the first switch in response to detecting the activated transducer while the device measures the time it takes for this activity, thereby defining the athlete's reaction time. Then, the athlete manipulates the spaced apart second switch while the system monitors the time it takes to perform this task, thereby defining the athlete's performance time. The total response time is then calculated by adding the reaction time to the performance time. A testing protocol for performing a plurality of timed tests and averaging the scores is also disclosed.
