I have a diploma in automotive collision repair and know how to estimate damage.
Should I get my pre-licensing First?? I live in NC also

Usually, you get hired by a company first, who then sponsors you to get your adjusters' license. At some companies, it may be possible to start as an assistant and work your way up, but I think most adjusters have some sort of 4 year degree.

But don't let that discourage you- get out there and apply!
