Firstly, let me admit that the title may have not made sense. I've been searching online for various Criminal Justice jobs and came across the county applications for a correctional officer. None of the requirements mention taking the Civil Service Exam, but some made it seem as if they had their own exams to be taken during the application process. I've also signed up for the Middlesex Sheriff's C/O entrance exam & have started filling out various applications for other counties (along with taking the Civil Service C/O I exam this year). So, my question: Why are county C/O's not hired via the Civil Service exam? What's the difference between a County C/O and a regular C/O? Or am I just crazy and misunderstood the whole process?
