No, they used to have a test for DMH/DPH police officers. This was a separate test from the regular civil service police examination. WHen I worked for them a while ago I was told that I would have to take the next test if they offered one to keep my job, all i had to was pass. The test never happened, I believe the last one they had was over 14 years ago. Different civil service and you cannot lateral to a municipality.
