I don't know what type of civil service exam you're taking and why. Generally one gets an MSW degree http://www.bls.gov/oco/ocos060.htm and then there are all sorts of jobs available in the field.

If it's specific training for a specific job, they'd probably be able to tell you what the job entails more than a "generic" CPS title? If it's third party training, I'd check and make sure it's accredited and there are jobs, etc.

I'd look at specific jobs in your area and do what they say to get the job rather than third party stuff?
