Various responsibilities are to be accomplished in order to become a certified ultrasound tech. Complete training can be acquired from accredited training institutions offering sonography programs. There are three options to be considered as applicant for the certification exam. The applicant must finish one of the programs; one-year programs, two-year associate degree programs or the four-year bachelor degree programs. After acquiring any of the available degrees for ultrasound courses, the student graduates and is now ready to take certification examination to get a license.

Before securing a certification from the American Registry of Diagnostic Medical Sonographer, there are certain requirements for the applicant. It is required for the applicant to finish an associate degree or bachelor’s degree program to be able to take an examination and become a registered diagnostic medical sonographer (RDMS). The certification doesn’t end here.

Before a registered technician is able to register with ARMDS, it is a requirement to pass the examination in the sub specialty like obstetric and gynaecologic sonography, abdominal sonography, ophthalmologic sonography, vascular sonography or neurosonography. Aside from the sub specialty examination; it is also required to pass the general physical principles as well as the examination in instrumentation.

Upon passing all the required examination, the technician gets the license. However, all ultrasound sonographers are required by the ARMDS to have a continuing education so that he stays in touch with the new developments in the field of sonography.

In every examination the ultrasound technician may take, it is needed for him to review and practice answering questions related to the examination. Here is a sample of an examination the sonographer will encounter in the series of tests he will be taking for the certifications.
