Do yourself a favor and finish school first. If you start applying now and end up getting hired, they aren't gonna wait for you to finish school, and it's just too hard to juggle both full-time school/full-time job. Therefore, you may have to drop out, thus killing your chances of moving up the ladder since you won't have a degree. Go to school, look at internships, graduate, then either go to academy or start applying. That's what I'm doing, and I get the feeling from other officers on here that it's the best way to go. By the way, where in Western PA do you live and where are you going to school? Good luck.
