The King-Devick is a simple test that can be administered on the sidelines in less than two minutes, explains Troy Buchanan Principal Dr. Jerry Raines “It’s a very fast, two minute, sideline examination. We’re making database decisions instead of subjective decisions. In the past it was ‘What’s today? What did you have first hour?’ Those are more subjective. We always subscribe to ‘When in doubt, sit ‘em out,’ but this allows us to have data behind that decision. Ultimately it’s for the safety of our kids.”
