The King-Devick Concussion Screening Test is an objective, rapid sideline assessment tool designed to identify potential concussions in athletes. It can be administered efficiently by parents, coaches, athletic trainers, or healthcare professionals within minutes. Peer-reviewed research indicates that the King-Devick Test offers a reliable and valid method for detecting concussion symptoms during acute evaluations.

This tool is particularly relevant across various sports such as football, hockey, soccer, and basketball, as well as during other contact or collision activities both on and off the field.

The test requires athletes to read aloud a sequence of single-digit numbers from left to right on three different test cards. The assessment effectively detects impairments in eye movement, attention, language, and concentration—areas commonly affected by concussion.
