College kids all want to be police officers. They don't seem to have a problem with being an intern because that is part of the price they pay to get through school. Being a CSO seems to be below them which does not bode well for how they will treat a CSO in the future when they are a patrol officer. We had a candidate for CSO who came from a court security position and some day wanted to become a patrol officer. He paid so little attention to being a CSO that he was not offered a permenant position.
There are plenty of mature people out there looking for a change and hoping to get into a position where they can help others. The problem is that these people need a real wage. Going with a "college student" is a way to keep the wages down.

I work for a college and the best way to get students involved is to talk to the head of the law enforcement program at the colleges in your area. They may be able to help you with getting students who are interested. Good Luck.

i'm going to be applying for a cso job on monday, i stumbled across this researching the job.. i was worried that being the age of 19 and not having much experience that i wouldn't even get considered, but this made it seem very promising as your post is exactly why i want to do it.
