INTRODUCTION
The Pathologists' Assistant Interview Exam is a comprehensive, multi-station assessment
used by hospital systems, academic medical centers, and private pathology laboratories to
evaluate candidates for Pathologists' Assistant (PA) positions. This exam serves as the final
benchmark before hiring, assessing both technical competency in surgical and autopsy
pathology and the non-cognitive qualities essential for success in the anatomic pathology
laboratory. The interview exam is specifically for certified or certification-eligible
Pathologists' Assistants who have completed an NAACLS-accredited master's program and
are seeking employment in hospital-based or independent pathology practices. Passing this
multi-faceted assessment is critical for securing a position and demonstrating readiness for
independent grossing and autopsy responsibilities.
The exam format consists of 200 scored scenarios delivered across multiple interview
stations, including technical grossing questions, autopsy scenarios, ethical dilemmas,
teamwork simulations, and situational judgment exercises. The exam covers key domains
including surgical pathology grossing (30%), autopsy pathology (20%), laboratory operations
and safety (15%), communication and professionalism (15%), ethics and legal considerations
(10%), and quality assurance (10%). Candidates must demonstrate both depth of technical
knowledge and the communication skills required to interact with pathologists, surgeons,
laboratory staff, and families during autopsy discussions.
This comprehensive question bank contains 200 advanced, scenario-based practice
questions that mirror the actual interview exam's content domains and cognitive complexity.
Each question is accompanied by a well-explained rationale that not only identifies the
correct answer but also provides the underlying pathology principle or professional
competency and explains why each distractor is incorrect. The correct answers are
distributed across all four options to prevent pattern recognition. By working through these
questions, you will strengthen your technical knowledge, master the application of
pathology principles to real-world scenarios, and significantly increase your chances of
passing the Pathologists' Assistant Interview Exam on your first attempt.
CORE DOMAINS TESTED
The Pathologists' Assistant Interview Exam is organized around the major content areas
specified in the ASCP PA(ASCP) Examination Content Guideline and NAACLS accreditation
,2
standards. Each domain reflects the critical knowledge and skills required for independent
practice as a Pathologists' Assistant.
1. Surgical Pathology Grossing (30%): Covers specimen orientation, dissection
techniques, margin assessment, lymph node harvest, tumor staging, section
selection, and documentation for a wide range of surgical specimens including
breast, colon, prostate, lung, and skin.
2. Autopsy Pathology (20%): Covers external examination, evisceration techniques,
organ dissection, microscopic section selection, cause of death determination, fetal
and perinatal autopsy, and autopsy documentation including preliminary and final
reports.
3. Laboratory Operations and Safety (15%): Covers formalin safety, PPE, frozen section
techniques, tissue processing, quality control, equipment maintenance, and
laboratory workflow optimization.
4. Communication and Professionalism (15%): Covers communication with
pathologists, surgeons, laboratory staff, and families; conflict resolution; teamwork;
and professional conduct in high-stress environments.
5. Ethics and Legal Considerations (10%): Covers informed consent, confidentiality,
chain of custody, research ethics, and the PA's role in legal and regulatory
compliance.
6. Quality Assurance and Process Improvement (10%): Covers specimen tracking,
turnaround time optimization, error prevention, root cause analysis, and
participation in laboratory quality improvement initiatives.

QUESTIONS 1-200
Q1: During an interview, you are asked: "How would you gross a
colon resection for adenocarcinoma?" Which of the following
represents the correct first step in your approach?
A) Open the specimen longitudinally along the mesenteric border
immediately
B) Review the institutional SOP and CAP staging protocol, then
confirm patient identifiers and clinical history
C) Measure the specimen and section the tumor immediately
D) Ink the entire serosal surface before opening the specimen
Rationale: The correct answer is B. The first step in grossing any
specimen is to review institutional SOPs and CAP staging protocols,
confirm patient identifiers, and review clinical history including
imaging and prior biopsies. This ensures safe and organized grossing
practices. Option A is incorrect because opening should follow review
of protocols. Option C is incorrect because measurement follows
specimen identification and orientation. Option D is incorrect because
inking follows orientation and opening.
Q2: A surgeon requests a frozen section on a breast lumpectomy
specimen for margin assessment. What is the most appropriate
action?
A) Perform the frozen section independently and report results to the
surgeon
B) Assist the pathologist by grossing the specimen, identifying
margins, and preparing tissue for frozen section
, 4
C) Refuse the request because frozen sections cannot be performed
on breast tissue
D) Send the specimen for permanent processing without frozen
section
Rationale: The correct answer is B. The PA's role is to assist the
pathologist by grossing the specimen, identifying margins, and
preparing tissue for frozen section. The pathologist interprets the
frozen section and communicates results. Option A is incorrect
because PAs do not independently diagnose. Option C is incorrect
because frozen sections are commonly performed on breast tissue.
Option D is incorrect because frozen section is specifically requested
for immediate intraoperative decision-making.
Q3: During an autopsy, you discover a suspicious finding that was not
documented in the medical record. What should you do?
A) Ignore the finding because it was not documented
B) Document the finding thoroughly, photograph it if appropriate,
and notify the pathologist
C) Remove the finding and discard it
D) Wait until the final report to mention the finding
Rationale: The correct answer is B. Any unexpected finding should be
thoroughly documented, photographed if appropriate, and
communicated to the pathologist. Option A is incorrect because all
findings must be documented. Option C is incorrect because
discarding findings is inappropriate and unethical. Option D is
incorrect because the pathologist should be notified promptly.
