Also, the private gyms around here pay more for a CSCS, then someone who is just a certified personal trainer, but that's not universal. The private gym I work actually pays you accordig to how many and what certifications you hold, but again, not universal. The more qualifications the better, imho (to an extent). Sometimes it's your arsenal of certs that edges out the next guy.
NSCA - CSCS
Hell, there are a good share of "S&C" gym owners in Orange County, CA who wear shirts that say Strength & Conditioning Coach and probably aren't even CPR certified, let alone CSCS. As long as it doesn't say Certified or NSCA on there, they can conduct business if they're owners.
NSCA - CSCS
MBA = Masters of Business Administration. I still don't understand why someone would need an MBA to work as a college strength coach.
I took the CSCS exam several years ago. I had a bachelor's degree in nutrition at the time. I studied the big NSCA textbook and got one exercise technique DVD and did well on the test. For a strength and conditioning job at a big school, a Master's degree will help. What will help even more is having internship experience and working with a program that is well connected in the S&C world. Many of those jobs are still more about who you know than what you know.
I did my Master's work at Appalachian State and I know their exercise science master's program has a track with a S&C focus. They also have good GA opportunities with the S&C staff, state-of-the-art stregth, speed, and body composition testing, and seem to have a decent track record of getting people connected for jobs after graduation.
