Tony,

WELCOME TO THE AWS WELDING FORUM!!

Look at this link:    http://www.aws.org/cgi-bin/mwf/topic_show.pl?pid=192255;hl=Certified%20Welding%20Supervisor

It is titled "CWS exam- worthwhile?" 

If you use the 'Search' function at the center top of the page and enter 'Certified Welding Supervisor' you will find many other references where the CWS program is referenced.

Hope this helps.

Have a Great Day,  Brent
