"Any time you have an opportunity to make a difference in this world and you don't, then you are wasting your time on Earth."

Roberto Clemente

A Message From Clarence Carlos, Founder of RC21X

I started RC21X as the result of a tragedy. A young man named Kyle Wilson, the son of my close friend, suddenly fell ill. After being rushed to the hospital, the illness went un-diagnosed because the medical staff—despite all obvious signs—could not produce a measurement for the changes in Kyle. Sending Kyle away based on what they could measure and missing what was really happening resulted in this young man passing away. 

Kyle's death could have been avoided. If the staff had access to objective measures of his performance, they could have kept him under observation to delve further into his condition. I attended Kyle’s funeral, and it changed my life. After seeing the raw emotion of his family and friends, I vowed to discover and make available to everyone measures of human performance that could be used universally.

In partnership with the Clemente Family and the University of Texas at Arlington we have developed THE standard for measuring and assessing human performance.
