Depending on your state, employers may have access to your RAP sheet, and these records may contain errors.
You should get a copy of your own RAP sheet and review it for errors. If you are certain you only have arrests or convictions from one state, you can get your RAP sheet from that state. If you have ever been arrested in more than one state, you should get your FBI RAP sheet, as well as your RAP sheet from each state in which you have had any arrest or conviction.
Your RAP sheet should be accurate because mistakes on your criminal record can keep you from getting a job, keeping a job, and getting promoted. You also want to get your RAP sheet so that you can accurately answer questions on a job application and discuss your record with an employer.
