I'll just add some 1st hand experience I have with the Wonderlic Exam for those who might think is has no real value or is not an excellent evaluation tool.
I've been a School Director for well over 30 years. I've used the Wonderlic Exam as a part of my Entrance Requirements for all of that time and more going back to 1988. It is one of the best exams available for evaluating basic education level skills that any Post Secondary School can use... I think it is the absolute best. It is also extremely easy to administer and it only takes a max of about 30 minutes to take. That's the basic time limit but most people don't need that much time to complete it.
Someone said earlier that it is easy to tell if someone isn't bright. Well I'm here to tell you that that isn't the case at all. I know this for sure only after watching this very test being given to countless people for decades. There are many people around you every day who seem bright/normal... in other words... someone who is obviously smart enough to go through life without any problems. What most people never realize is that many of the people around you who actually have very poor learning abilities or little to no education are people who are able to mask this weakness of theirs with amazing skill. Many many times... the people who absolutely bomb on a basic test like this one are the last people that you would ever expect to. It is absolutely amazing to me how well many of these people are able to basically completely hide this serious weakness from everyone when you are just speaking to them in person. Rather than seek out the help they might need, these people would rather just try and fake their way through things. I never would have believed just how many people there are out there like this until I used this test as an evaluation tool. And like I said... most of the time it's the last person you'd ever suspect.
Tools like this are extremely important in the school business because it is our job as educators to determine someone's ability to benefit from the a class or training program PRIOR to them being accepted into it. This same exact thing applies to real life jobs... and being a professional football player is a real serious job that absolutely has prerequisites for anyone who hopes to be successful doing it.
There are a tremendous number of examples of people who scored extremely poorly on this exam prior to entering the league who failed miserably once they got in. Of course there are a few exceptions to most things... this included. But to say that this test being administered to guys trying to get a job as a player in the NFL is not useful in a very big way is absolutely wrong.
Many years ago I actually posted a real Wonderlic Exam here on ROD for people to try for themselves so that they could see how they scored. I'm sure it's still here somewhere way back in the oldest pages of Ram/NFL talk if you'd like to check it out yourself.
