This DSST covers much of the same material you'll encounter on the Criminal Justice DSST. For that reason, it makes sense to take the two exams as close together as you can manage. I’d even suggest taking them on the same day. Once you’ve learned the content for one, there’s a good chance you’ll be ready to pass the other as well. As with the Criminal Justice DSST, those with a law enforcement background will have an advantage, but anyone can pass with some dedicated study. This exam places a strong emphasis on court cases and constitutional amendments, so pay particular attention to those areas while preparing.
