Pathologists' Assistant field

We accepted our first students in the fall of 2020. We will publish student certification, graduation and placement rate outcomes once we have them.

If you graduate from our program, you will be eligible to take the Canadian Certification Council of Pathologists’ Assistants (CCCPA) certification exam.

We are currently working toward full accreditation by the National Accreditation Agency for Clinical Laboratory Sciences (NAACLS). We have achieved the “serious applicant status” with NAACLS and you will be eligible to take the American Society of Clinical Pathology Pathologists’ Assistant (PA (ASCP)) certification exam upon graduation.

What is a Pathologists' Assistant?  

As a Pathologists’ Assistant (PA), you would be an important member of the healthcare team who provides high-quality patient care.  

You are a highly trained professional who provides anatomic pathology services under the supervision of a certified pathologist.  

You are involved in providing various services in anatomic pathology, typically including:  

  • preparing and examining surgical pathology specimens  
  • performing postmortem examinations  
  • being involved in laboratory operations (regulatory, quality improvement, management activities, education, and research).  

Your gross examinations allow the pathologist to render their diagnosis.  

You will often work in a hospital, Forensic Services office, or other laboratory in a private or university setting.
