Analyst Exam 2026/2027: Exam
Review, Practice Test, and Success
Guide
Question 1:
A behavior analyst is deciding whether to recommend a restrictive intervention that
may quickly suppress a client’s behavior. Which consideration best reflects the
primary purpose of ethical practice?
A. Protecting the organization from criticism
B. Demonstrating the analyst’s technical authority
C. Furthering the welfare of the client
D. Selecting the least expensive intervention
Correct Answer: C. Furthering the welfare of the client
Rationale: Ethical practice primarily exists to protect and advance the client’s welfare.
Organizational reputation, professional authority, and cost may be relevant
considerations, but they must not override the client’s well-being. An ethical analyst
examines effectiveness, risks, social validity, client preferences, and possible harm
before selecting an intervention rather than prioritizing convenience or institutional
interests.
Question 2:
Which set of questions provides the broadest ethical framework for evaluating a
behavior analyst’s professional conduct?
A. Is it legal, affordable, and supported by management?
B. What is right, what is worth doing, and what defines a good behavior analyst?
C. Is it observable, measurable, and easy to implement?
D. What does the client want, what does the payer approve, and what does the
supervisor prefer?
Correct Answer: B. What is right, what is worth doing, and what defines a good
behavior analyst?
Rationale: The material identifies three fundamental ethical questions: what is the
right thing to do, what is worth doing, and what it means to be a good behavior
analyst. The other choices include potentially useful practical considerations, but they
do not provide a complete ethical framework. Ethical analysis extends beyond legality,
measurement, funding, or administrative approval.

Question 3:
A procedure was widely accepted in behavior-support programs 25 years ago but is
now viewed as unnecessarily restrictive. What is the most appropriate ethical
conclusion?
A. Previously accepted procedures remain ethical indefinitely.
B. Historical acceptance matters more than current professional standards.
C. Ethical judgments may change as cultural values and professional knowledge
develop.
D. The procedure is ethical whenever a client’s family requests it.
Correct Answer: C. Ethical judgments may change as cultural values and
professional knowledge develop.
Rationale: Ethical practice must account for differences across time and cultures. A
procedure’s historical acceptance does not guarantee that it remains appropriate today.
Current evidence, professional standards, client rights, social values, and less
restrictive alternatives should guide decisions. A family request also does not make an
outdated or harmful procedure ethically acceptable.
Question 4:
A behavior analyst was raised in a household that used harsh discipline. When a child
engages in aggression, the analyst immediately recommends overcorrection despite
having stronger training in differential reinforcement. What should guide the decision?
A. The analyst’s childhood experiences
B. The family’s preferred disciplinary traditions
C. The analyst’s professional training and scientific evidence
D. The intervention that produces the fastest visible punishment
Correct Answer: C. The analyst’s professional training and scientific evidence
Rationale: Professional training should override personal history when clinical
decisions are made. Personal experiences may create biases toward harsh or familiar
responses that are not clinically justified. The analyst should rely on behavior-analytic
evidence, competence, assessment results, risks, and client needs. Speed or family
tradition alone cannot establish that an intervention is effective or ethical.
Question 5:
A practitioner realizes that personal religious and cultural beliefs are interfering with
objective treatment planning. What is the most appropriate initial response?
,2026/2027
A. Continue treatment without acknowledging the conflict
B. Consult supervisors, experienced colleagues, and relevant research
C. Persuade the client to adopt the practitioner’s beliefs
D. Transfer the case immediately without attempting consultation
Correct Answer: B. Consult supervisors, experienced colleagues, and relevant
research
Rationale: When personal history may impair judgment, the practitioner should first
seek supervision, consultation, and scientific guidance. These supports may help the
analyst recognize bias and restore competent decision-making. Imposing personal
beliefs is inappropriate, while ignoring the concern risks client harm. Withdrawal
becomes appropriate when the analyst cannot obtain assistance or prevent the conflict
from affecting services.
Question 6:
After consultation, a behavior analyst remains unable to separate personal beliefs
from treatment decisions. What is the most ethical action?
A. Continue because ending services would always constitute abandonment
B. Ask the client to accept the analyst’s personal values
C. Excuse oneself from the case while arranging an appropriate transition
D. Allow an untrained staff member to make treatment decisions
Correct Answer: C. Excuse oneself from the case while arranging an appropriate
transition
Rationale: If personal history continues to compromise professional judgment despite
consultation, the analyst should withdraw responsibly. This requires protecting
continuity of care, discussing service needs, and facilitating transfer to a qualified
provider. Continuing impaired practice may harm the client. Abrupt withdrawal or
delegation to an unqualified person would also violate the obligation to protect client
welfare.
Question 7:
A behavior analyst works in both a public school and a private home program. Why
must the analyst evaluate the context of practice before implementing the same
procedure in both settings?
A. Context determines whether data collection is necessary.
B. Context may affect legal, organizational, and ethical requirements.
C. Home-based services are exempt from ethical standards.
D. School policies always override professional ethical obligations.
Correct Answer: B. Context may affect legal, organizational, and ethical
requirements.
, 2026/2027
Rationale: The context of practice includes the setting and nature of the professional
role. Different environments may have distinct laws, policies, consent requirements,
staffing conditions, and restrictions. Ethical responsibilities remain applicable in all
settings, but implementation may need adjustment. Organizational policy does not
automatically override professional ethics, and data-based decision-making remains
necessary regardless of location.
Question 8:
Which action may be legal in some jurisdictions but remains unethical under the
professional principles described in the content?
A. Stealing a client’s property
B. Physically abusing a client
C. Accepting a valuable family heirloom as payment
D. Falsifying the qualifications offered to a client
Correct Answer: C. Accepting a valuable family heirloom as payment
Rationale: Accepting a valued heirloom may not necessarily violate criminal law, but
it creates boundary, exploitation, barter, and conflict-of-interest concerns. Stealing,
physical abuse, and misrepresentation are both illegal and unethical. Ethical conduct
requires analysts to consider professional boundaries and client vulnerability even
when an action is not expressly prohibited by criminal law.
Question 9:
Which conduct is most clearly both illegal and unethical?
A. Discussing a difficult case with an authorized consultant
B. Charging an agreed-upon professional fee
C. Declining a case outside one’s competence
D. Misrepresenting services and taking payment for work never provided
Correct Answer: D. Misrepresenting services and taking payment for work
never provided
Rationale: Misrepresenting services and accepting payment for services not delivered
involve fraud and violate professional integrity. Authorized consultation, appropriate
fees, and declining work outside one’s competence can all be ethical. Ethical analysts
accurately describe their skills, services, charges, and outcomes and must not deceive
clients, payers, employers, or other affected parties.
