Pathologists' Assistant

Pathologists' Assistant Overview


To work as a pathologists’ assistant (PA), you must complete an intensive training program to become one of these highly trained health professionals. You will work under the instructions and supervision of a licensed pathologist who is board-certified or board-eligible to provide anatomic pathology services.

As a pathologists’ assistant, you’ll not be allowed to make a final diagnosis in a case but you will be qualified to perform surgical procedures and autopsy functions that a pathologist performs.




The pathologists’ assistant may provide the following services under the supervision and direction of a pathologist:

  • Gross description, preparation and dissection of surgical specimens of human tissue

  • Preparations necessary for human post-mortem examinations

  • Instruction in anatomy and physiology

  • Education in gross pathology

  • Anatomical photography

  • Gross dissection skills of surgical specimens

  • Standard autopsy techniques

  • Clinical training of pathologists’ assistant students, residents and fellows in pathology and any other personnel who will be working in the pathology lab

  • Participate in ongoing research

  • Obtain samples used for bio-specimen banking

  • May be required to perform other assigned duties, including administrative, supervisory, budgetary and teaching duties

Because of the wide variety of tasks performed by pathologists’ assistants, these allied health professionals make a significant contribution to the effectiveness and cost efficiency of a pathology practice or a laboratory.

Working Conditions


A pathologists’ assistant is expected to perform a wide variety of clinical procedures. The majority of pathologists’ assistants work in academic settings, such as a medical school or university, or a community hospital. Others areas of potential employment include:

  • Private pathology laboratories

  • Morgues

  • Forensic pathology laboratories

  • Governmental health care system laboratories

  • Reference and research laboratories

  • Medical teaching facilities

  • Some pathologists’ assistants may work for themselves as self-employed business owners.

Second Year - Fall (9 hrs)

  • Path Assistant Practicum III - 7 hours
  • Pathology Review II - 2 hours

 --- 2 Year Total - 74 hours


3. Earn the Required Certification


National Certification for Pathologists’ Assistants was achieved in 2004 through the efforts of the American Association of Pathologists’ Assistants (AAPA) and the American Society for Clinical Pathology (ASCP). In order to earn a PA or ASCP designation, graduation from a pathologists’ assistant program that is accredited by the NAACLS is now required. The graduate must then successfully complete the examination for ASCP board certification.


4. Maintain Certification Through Continuing Education


As a certified pathologists’ assistant, you will be required to demonstrate sufficient continuing medical education to maintain your certification. You must complete continuing education and re-certify every 3 years. ASCP requires 45 Continuing Education credits for every three-year period of certification. Those must include at least one credit in safety and twenty credits in anatomic pathology. An ASCP renewal form must be sent to ASCP two months before the end of your 3 year period.
