The NFL used the Wonderlic test for 50 years to measure QB's intelligence in the NFL Draft process. The Wonderlic tested general intelligence and many felt it was not a good tool for predicting success in the NFL. A new test was developed out of Nashville called the S2 Test to determine how a player might succeed in the NFL (mostly QB's). How does it work?
The S2 Cognition test evaluates athletes in four categories with subcategories in the first three and then provides an overall score in the form of a percentile where the athlete falls among his or her peers.
