1. What is the primary purpose of ethical conduct in private
investigations?
A. To increase the investigator’s fees
B. To help ensure investigations are lawful, fair, and professionally
responsible
C. To guarantee that every client obtains the desired result
D. To eliminate the need for documentation
Correct Answer: B. To help ensure investigations are lawful,
fair, and professionally responsible
,Rationale: Ethical conduct establishes professional standards
that guide an investigator’s decisions and actions. It helps protect
clients, subjects, witnesses, and the investigator while supporting
lawful and responsible investigative practices.
2. A private investigator should generally accept an assignment
only when the investigator can:
A. Guarantee the client’s preferred outcome
B. Complete the assignment without keeping records
C. Perform the work competently and within applicable legal and
professional boundaries
D. Avoid communicating with the client
Correct Answer: C. Perform the work competently and within
applicable legal and professional boundaries
Rationale: Professional responsibility requires an investigator to
understand the assignment, possess or obtain the necessary
competence, and operate within applicable legal and ethical
limits. An investigator should not accept work that cannot be
responsibly performed.
3. A client asks an investigator to obtain information through
deception that would violate the law. What is the most ethical
response?
A. Perform the request because the client is paying
B. Perform it but avoid documenting the activity
C. Refuse the unlawful portion of the assignment
D. Ask another investigator to perform it secretly
,Correct Answer: C. Refuse the unlawful portion of the
assignment
Rationale: A client’s authorization does not make unlawful
conduct permissible. An investigator has an independent
professional responsibility to comply with applicable law and
should decline requests that require illegal conduct.
4. Which principle is most important when handling confidential
client information?
A. Share it with anyone who asks politely
B. Disclose it only when authorized or when disclosure is
otherwise legally required or permitted
C. Post it online after the case closes
D. Discuss it with unrelated clients
Correct Answer: B. Disclose it only when authorized or when
disclosure is otherwise legally required or permitted
Rationale: Confidentiality is a fundamental professional
obligation. Investigative information should be protected and
disclosed only when the client authorizes disclosure or another
legitimate legal basis permits or requires it.
5. An investigator discovers that a potential assignment involves a
close personal relationship with the subject. What should the
investigator do first?
A. Hide the relationship from the client
B. Evaluate the conflict of interest and disclose it as appropriate
, C. Immediately destroy all case information
D. Increase the investigation fee
Correct Answer: B. Evaluate the conflict of interest and
disclose it as appropriate
Rationale: A personal relationship may compromise—or appear
to compromise—objectivity. Professional conduct requires
investigators to recognize potential conflicts and take appropriate
steps, including disclosure or declining the assignment when
necessary.
6. Why should an investigator avoid making promises about the
outcome of an investigation?
A. Investigators cannot control all facts or circumstances
B. Clients dislike accurate information
C. Promises are required to be written in advertisements
D. Investigators are expected to guarantee results
Correct Answer: A. Investigators cannot control all facts or
circumstances
Rationale: Investigative results depend on evidence,
circumstances, witnesses, records, and other factors outside the
investigator’s control. Ethical investigators describe the services
they can provide rather than guaranteeing a particular result.
7. A professional investigator discovers evidence that contradicts
the client’s theory. What is the appropriate course of action?
A. Conceal the evidence
B. Alter the evidence
