The SSC is growing. 2 years ago, I'd never heard of it, recently, I was asked if I had ever read starting strength during a job interview at a local country club. The world of strength and conditioning is changing too. The CSCS used to be the top cert, now things like the Collegiate Strength and Conditioning Coaches Association's CSCC and the SSC are gaining momentum for good reason, they cater more toward scientifically proven training. I am unsatisfied with the NSCA, it does not cater to me, it caters toward people who need to be taught how to do a prone leg curl machine.
In my job searches, I have found only one college that listed the SSC as a preferred requirement but that is big news.
I am a strength coach and hold the CSCS and USAW but plan to drop the CSCS in the next cycle most likely in 2017 to stop having to give money to the NSCA. I get more educational information from the CSCCA website and here than I did when I PAID for the NSCA Journal of Strength and Conditioning. I am considering going to a SSC but need time to see if I plan to go into business for myself or if I land a university gig. If people ask now though, I tell them to look into starting strength whereas people 10 years ago in my shoes were telling people to check out the NSCA.
