What is Your Team's Application Process?

[Lij2015]

Our team this year had a problem that its never had before, too many people on it.
Our build space is a small shop that can probably only fit 15 or so people working (Which isn't really a problem as our mechanical team wasn't bigger than that this year) in it at a time and we only have two smaller sized classrooms for the other type work. So we are debating some sort of application or evaluation process for new members and cutting old ones (this isn't my question, I know exactly who I'd cut)

This year we almost grazed 40 students and probably about 10-12 of those students were super apathetic and didn't care to actually do anything. Since we have a pretty open policy on who can be there it kind of just happened and this caused some administrative nightmares.

What selection or evaluation process does your team have for selecting the students on it? Also if any of those processes involve an application I'd love to see a few examples!
