It typically takes about 2 years to become a sonographer. This includes completing a formal education program in sonography, which can be a certificate, associate’s degree, or bachelor’s degree program. The specific length of time it takes to complete a sonography program will depend on the type of program you choose and whether you attend school full-time or part-time. In addition to completing a formal education program, most states also require sonographers to be licensed or certified, which usually involves passing a written exam.
