The acronym for “certified electron microscopy technologist” is CEMT, and these letters designate the bearer as having passed the written and practical exams necessary to become “certified”! The acronym was approved by the MSA Council to more firmly provide a professional identification of certification in the area of transmission electron microscopy (TEM) of biological tissue. A CEMT may use these initials after his or her name for as long as the certification remains valid (for example, Jane Doe, AA, BS, CEMT).
