grad_Photo4.jpgThis M.S. track focuses on the education of pathologists' assistants.  Pathologists' assistants provide service in anatomic pathology under the direction and supervision
of a qualified anatomic pathologist, with responsibilities including gross surgical pathology, frozen section preparation, and autopsy pathology.  This program is not research-based, and no thesis is required.  The program is designed to serve individuals holding baccalaureate degrees in various science-related fields (clinical laboratory science, cytotechnology, biology, chemistry, etc.) who have an interest in pathology, particularly the anatomic aspect of pathology.

Pathologists' Assistant Career Responsibilities

The Pathologists' Assistant is qualified by academic and practical training to provide the following services and others under the direction and supervision of a pathologist:
Preparation, gross description, and dissection of human tissue surgical specimens including the following: obtaining clinical history, describing gross anatomic features, dissecting surgical specimens, preparing tissues for histologic processing, and photographing all pertinent gross specimens and microscopic slides

Preparation of human postmortem examinations including the following: conferring with the attending pathologists to identify any special techniques and procedures to be utilized in the completion of the postmortem examination, performing postmortem examinations, selecting, preparing and submitting appropriate gross tissue sections, performing special procedures such as coronary artery perfusion, central nervous system perfusion, enucleation, inner ear bone dissection, spinal cord removal, etc., and organizing information pertinent to the preparation of the preliminary summarization of the clinical history.

Freezing tissue removed at surgery in preparation for intra-operative examination by a pathologist.

Performing such administrative, budgetary, supervisory, teaching, and other duties as may be assigned.

Curriculum for the Pathologists' Assistant M.S. Track:

The 22-month curriculum for the Pathologists' Assistant track is standardized, beginning with a full year of basic science courses and featuring a second year that highlights anatomic pathology techniques courses and practical experience.


 Year 1 Fall: Basic Histology D502
Human Physiology F503
 Year 1 Spring: Gross Anatomy D501
Infectious Microbes and Host Interactions J510
Techniques in Specimen Processing C690
 Year 1 Summer Gross Surgical and Pediatric Pathology Techniques C691
Autopsy and Forensic Pathology Techniques C692
 Year 2 Fall General and Clinical Pathology C693
Practicum for Pathologists' Assistants C695
 Year 2 Spring Systemic Pathology C694
Practicum for Pathologists' Assistants C695
 Year 2 Summer Practicum for Pathologists' Assistants C695

C695 Practicum for Pathologists’ Assistants includes 9-10 months of clinical rotations, starting in mid-August and ending at the end of June. These rotations include gross surgical pathology at the Indiana University Health Pathology Laboratory, autopsy pathology at the Indiana University Health Pathology Laboratory, frozen section management at Indiana University Hospital, gross surgicals and frozens at Eskenazi Health Hospital, surgicals/autopsies/frozens at Roudebush Veteran’s Medical Center Hospital, and forensic autopsies at the Office of the Marion County Coroner. All of these sites are located in downtown Indianapolis; all are within easy walking distance of the IU School of Medicine classroom facilities except the Marion County Coroner’s Office, which is approximately 2-3 miles away.

Although completion of this M.S. track does not require a research experience, interested students may opt to include a research experience.  Students pursuing the thesis option may substitute 2 credits of C859 Research in Pathology  for each of two elective 1-credit practicum experiences from the C695 Practicum for Pathologist Assistants.  At least two additional credits of C859 will be required.  Thesis-option students will continue their research after completion of all Pathologists' Assistant program requirements.  Research will continue until a project, with a thesis equivalent in all respects to other M.S. in Pathology projects/theses, is complete.  Thesis option students will also enroll in C808 Graduate Student Seminar for 1 credit. 

 Part-time Study: Part-time study is not recommended but may be approved for completing the first year curriculum for selected individuals.  However, full-time study is required for all students during the second year of the program. 

Pathologists' Assistant Accreditation, Certification, Etc. grad_Photo6.jpg

 Pathologists' assistant is a recognized specialty accredited by the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS), which has established the didactic and clinical experiences necessary for effective education of pathologists' assistants.  The Indiana University School of Medicine Program is fully accredited by NAACLS. 

 Upon completion of an accredited pathologists' assistant program, graduates are eligible to sit for the pathologists' assistant certification examination offered by the American Society for Clinical Pathology (ASCP) (  Passing the certification examination is not a requirement for M.S. degree completion, but the credential is required by most employers in the United States.

 The American Association of Pathologists' Assistants (AAPA) is the professional organization for pathologists' assistants in the United States.  The AAPA is the only national organization that unites pathologists' assistants and provides guidelines for their appropriate practice.  Visit the AAPA website at read more about the responsibilities and career opportunities of pathologists' assistants

 Demand for certified pathologists' assistants is high, and the employer demand exceeds the supply of pathologists' assistants produced at present.  Pathologists' Assistants may work in academic medical centers, community hospitals, private laboratories, coroners' and medical examiners' offices, and other locations in which their services are needed.
