LEED Campus vs LEED Schools vs LEED NC

I'm confused and could use a bit of help. We are in the pre-design phase of a new student center on a higher ed campus that I don't believe has any other LEED certified buildings on it. I am attempting to prepare for our first eco-charette but would like to go in with a rating system to recommend. The problem is, I can't seem to figure out which system would be best. Each of them seem like they could work. My current assumptions are as follows: - they will likely want to certify other projects in the future - the student center will likely contain 60% Can anyone help? I've gone through the "which rating system" worksheet but it doesn't cover LEED Campus. Thank you!
