That's the National Conference for College Women Student Leaders, and it's pronounced "Nick-whistle."

I learned about the conference at an AAUW meeting. I suspect that many may not know about it. Now you do, and I hope you will consider attending.
If you work your way thru the website you'll see that there is financial aid available. I think that your local AAUW branch--maybe in your hometown, if not in your college town--might be willing to defray expenses. If you need more info about AAUW locally, PM me.
