An associate or bachelor's degree is typically required to pursue employment as a diagnostic medical sonographer. Students also have the option to graduate with a degree in a related field, pursue a certificate program in diagnostic medical sonography and then receive on-the-job training.nly a few states require sonographers to be licensed.

This message will only be visible when you check your mail using POP. Despite what the message says, it is safe to delete it.
