Even if you decide to possibly break any rules or laws (which I don't recommend, but yeah, I'm a Dad too)- look at the college/university's website and go their Police Dept page. See if they have links to self defense training. A very popular program at a lot of insitutions now is RAD. I forget what the acronym stands for, but it's a self defense program where once the participant completes a 12 hr course- they are members for life and can return as often as they like for training or refresher courses.
Either way, shoot them an e-mail and ask about defense courses and programs. Learning defense not only teaches basic skills but it also builds confidence, situational awareness, agility, strength, ... and helps ward off those dreaded 'Freshman 15'.
