@navymomwannabe - I was under the impression that attending NASS did, in fact, increase your WCS. I could very easily be mistaken as I don't remember getting that information from a concrete source. However, even if attending NASS does not increase your WCS, your squad leader, a midshipman two years your senior, will fill out an assessment on you at the end of the seminar. Granted, this could hurt you, but NASS definitely should not be written off as something that won't buff up your application. I never went to Boys State, but, if I had to guess, I'd say that NASS would be a better time investment.
