What is the King-Devick Test?

What It Is

King-Devick Test is a validated, accurate and objective remove-from-play sideline concussion screening test. With results in less than two minutes, trained parents, coaches, athletic trainers, and medical professionals can quickly assess if an athlete requires additional medical attention. Find out more about concussions here.

How It Works

At the beginning of the season, establish a pre-injury baseline score on your iPad or Android tablet for your athlete. After a hard hit or suspected concussion, use the King-Devick Test app to screen your athlete right from the sidelines or at home.  According to our validated protocol, a worse post-injury test indicates that a concussion may have occurred and that your athlete should be immediately removed from play and evaluated by a licensed professional. Find out more here.

Where to Buy

The King-Devick Test is available for purchase for personal in-home use by parents for individual athletes or for larger athletic programs at the local club, high school and collegiate levels and beyond.
