Thanks to the hard work of our volunteer coordinators, 500 chapter competitions and 56 state competitions take place each year!
Many of our volunteer coordinators are Professional Engineers affiliated with the National Society of Professional Engineers (NSPE)—one of our founding sponsors—and many NSPE state and chapter societies support local MATHCOUNTS programming. Visit the National Society of Professional Engineers to learn more about engineering.
