ASCP BOC History

The American Society for Clinical Pathology Board of Certification (ASCP BOC) was founded in 1928 and will celebrate its 100th anniversary in 2028.

The following timeline highlights the evolution of the ASCP BOC and the influence of laboratory professionals who have shaped our certification processes from the 1920s to the present day.

1922 American Society of Clinical Pathologists (ASCP) is formed. 

1926 ASCP Committee on Registration of Technicians creates rules and regulations for governance of a registry.   

First report from the Committee on Registration of Technicians was presented by Dr. Kano Ikeda at the New Willard Hotel, Washington, DC, on May 23. 

1928 ASCP Board of Registry (BOR) is officially established to conduct a registration bureau called the “Registration Bureau for Technicians.”

The first chair is Phillip Hillkowitz, MD (1928-1940).

1930 First ASCP BOR certificate is issued to Paul H. Adams of Fort Wayne, IN.   

1931 ASCP BOR institutes the use of initials “MT” (Medical Technologist) and “LT” (Laboratory Technician) after the registrant’s name.   

Medical Technologist (MT) certification was established. 

1933 All registry applicants are required to take a written and practical examination.  Exams are 50% oral/practical, 25% written, and 25% personal/psychological. The examination fee is $10.  Of the 66 applicants who take the first nation-wide examination, 56 pass. 

1934 First separate meeting of Registry of Technicians is held in Cleveland, OH. 

1935 Becomes apparent that uniformity of grading cannot be accomplished by several scattered examiners.  First official examiner, Dr. A. W. Freshman, is appointed.   

The ASCP BOR decides to give the title Medical Technologist (MT) automatically to those certified Laboratory Technicians with college degrees. 

1936  Laboratory Technician (LT) title is discontinued, and all subsequent registrants are designated Medical Technologists.   

American Medical Association publishes the first AMA list of “Accredited Schools for Clinical Laboratory Technicians.” 

1938 ASCP BOR is 10 years old and has certified 4,465 technologists.
