Hi. My sister works for CPS. Granted, we’re in New York, but maybe I can help nonetheless. She has a BA in Sociology (but I don’t think a Sociology background was part of the requirements in any way) and no related work background. She took a civil service exam in the subject of health and social work and scored very well. I’m pretty sure that has a lot to do with why she was hired. She wasn’t trained for the job until after she was hired. She’s been going through a months-long training sequence in which she went to a training workshop put on by the CPS every other week and shadowed current CPS workers on the off-weeks. She loves her job. Good luck!
