OKLAHOMA CITY -- Concern over concussions is putting football and other sports in the spotlight a lot lately.
Some schools are on the offensive when it comes to keeping athletes safe.
Casady School in Oklahoma City is one of the ones being proactive.
It now requires upper division student athletes to take an online cognitive test at the start of the school year.
Headmaster Chris Bright said they are doing what they can to protect their students.
Bright explains, "It's a baseline test for cognitive function. We test memory, decision making, speed and we do that for every sport, not just football."
If a student suffers a concussion during a game or practice, that student will need to retake that cognitive test.
Medical professionals will use those tests to help determine when the athlete is healthy and able to play again.
Edmond and Yukon school districts are also requiring their athletes to take these tests.
