It's NOT an easy place to get in to, but you might wanna try Mass. General Hospital. There's plenty of old threads here about it.... do some research here. It's a GREAT stepping stone. Like I said, its quite competitive, but give it a shot.
I have been reading all these posts and while I have never worked at MassArt I know at least two officers who have and they both said the same thing...it's horrendous. They actually got to a poiint a couple of months ago where they only had one officer working there...what does that tell you.
If you are getting on as a reserve somewhere, focus your LE interest in that job and work a civilian full time job until something better comes up. MassArt has actually become a job where when you say you've worked there people look at you a little different wondering whether you are a good cop caught in the net there or did you fit in there, if you know what I mean.
Don't take the dive into an empty swimming pool and also don't ask the administration of the department the questions your wondering, ask the officers who have worked there.
