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.
