5 of the Hardest Questions on Our New ASWB Practice Exam 4

Some ASWB questions are hard because they test a precise definition. Others are hard because two or three answers sound reasonable. To help you prepare, we looked at results from Agents of Change Practice Exam 4, one of our four full-length, 122-question practice exams built for the new ASWB exam, and pulled five of the questions test-takers missed most often.

These results come from 92 test records through October 28, 2026. We didn’t simply pick the five lowest scores. We reviewed the lowest-performing questions and chose five that are clearly written and teach an important skill, so you can learn from them with confidence.

Try each question on your own first. Then scroll down for the answer, the rationale, why the question is tricky, and a strategy you can use on similar questions.

1) Try the Questions First

Question 1

A social worker provides counseling to a couple. During a session, one partner reveals an extramarital affair but asks that the social worker not tell the other. What is the MOST appropriate response?

A) Honor the request due to confidentiality
B) Discuss why not sharing with the partner may be harmful to the relationship
C) Discuss limits of confidentiality in conjoint therapy

Question 2

A researcher is interested in studying the relationship between physical activity and mental health in adults. The researcher recruits participants for the study by posting fliers at local fitness centers and asking sports coaches to recruit participants. Which of the following types of bias is most likely to be present in this study?

A) Self-selection bias
B) Investigator bias
C) Construct bias
D) Response bias

Question 3

A social worker has been hired to work within a corporate organization to support employee well-being. In this role, the social worker will develop mental health programs, provide counseling services, and assist in resolving workplace conflicts. This scenario exemplifies a social worker operating in a “host setting.” What does the term “host setting” primarily refer to in the context of social work?

A) A setting where there is a focus on multi-disciplinary collaboration for client care
B) A setting where social work functions are integrated into a broader system not primarily focused on social services
C) A private practice environment where social workers offer services to clients on an individual basis
D) An organizational environment where social workers primarily engage in policy development and advocacy rather than direct service provision

Question 4

You are a social worker working with a client who has been struggling with anger management issues. They tell you that they have been using sublimation as a coping mechanism, expressing their aggressive impulses through activities such as kickboxing and weightlifting. How do you respond?

A) Encourage them to continue using sublimation as a way to manage their anger
B) Explain that engaging in aggressive physical activities may cause an increase in their anger response
C) Suggest that they try to express their anger directly through assertive communication or other methods
D) Explore CBT as an alternative modality to help the client work on impulse control

Question 5

In single-subject design research commonly used in social work, the term “baseline” refers to a specific aspect of the study. What does “baseline” mean in the context of a single-subject design?

A) The initial phase where the intervention or treatment is first applied to the subject
B) The statistical method used to analyze the data collected during the study
C) The control group used for comparison against the subject receiving the intervention
D) The period during which the subject’s behavior or condition is observed without any intervention

2) Answers and Rationales

Question 1: Couples therapy and confidentiality

Correct answer: C) Discuss limits of confidentiality in conjoint therapy

Only 49% answered correctly (45 of 92 test records).

Rationale: When working with a couple, the social worker has obligations to both partners. Before deciding what to do with this information, the social worker should talk with the partner about the limits of confidentiality in couples work, including the policy on secrets that should have been explained during informed consent. That policy guides the next steps.

Why the other answers are tempting: About a third of test-takers chose B (discuss why not sharing may be harmful). It’s a reasonable conversation to have later, but it skips the foundation: what was agreed about confidentiality and secrets when treatment began. A (honor the request) could conflict with the social worker’s obligations to both partners. Practices handle secrets differently. Some use a “no secrets” policy, and others allow limited individual confidences. There’s no blanket rule that a therapist must always reveal an affair.

Strategy takeaway: In couples and family therapy questions, think about the agreements made at the start of treatment. The NASW Code of Ethics says social workers providing couples, family, or group services should seek agreement among the parties about confidentiality and inform participants of the limits.

Question 2: Research bias

Correct answer: A) Self-selection bias

Only 54% answered correctly (50 of 92 test records).

Rationale: Self-selection bias happens when people choose whether to participate, and the people who volunteer differ in important ways from the population being studied. Recruiting through fitness centers and sports coaches means participants are likely to be more physically active and health-focused than adults in general, which can distort findings about physical activity and mental health.

Why the other answers are tempting: The most popular wrong answer, D (response bias), drew 23% of responses. Response bias affects how participants answer questions, such as giving socially desirable answers, not who ends up in the study. B (investigator bias) involves the researcher’s expectations influencing results, and C (construct bias) involves a measure not capturing the concept consistently across groups. This scenario is about recruitment, so self-selection bias fits best. The scenario also involves convenience sampling, which is closely related.

Strategy takeaway: When a research question describes how participants were recruited, ask who is likely to be included or left out. If volunteers choose themselves, think self-selection bias.

Question 3: Host settings

Correct answer: B) A setting where social work functions are integrated into a broader system not primarily focused on social services

Only 58% answered correctly (53 of 92 test records).

Rationale: A host setting is an organization whose main purpose is something other than social work, but that employs social workers to support its mission. Examples include corporations with employee assistance programs, schools, hospitals, prisons, and the military.

Why the other answers are tempting: The most popular wrong answer, A (multidisciplinary collaboration), drew 18% of responses, and D (policy development and advocacy) drew 17%. Host settings often involve collaboration, but that’s a feature of many settings, not the definition. What makes a setting a “host” is that its primary mission is something other than social work.

Strategy takeaway: In host settings, social workers often need to explain their role, collaborate across disciplines, and balance the organization’s policies with social work values. Expect scenario questions that test those tensions.

Question 4: Defense mechanisms: sublimation

Correct answer: A) Encourage them to continue using sublimation as a way to manage their anger

Only 60% answered correctly (55 of 92 test records).

Rationale: Sublimation is a mature defense mechanism that channels unacceptable or aggressive impulses into socially acceptable activities. The client has found a healthy, constructive outlet and identified it themselves. Reinforcing that strength supports the client’s self-awareness and progress.

Why the other answers are tempting: The most popular wrong answer, D (explore CBT as an alternative), drew 24% of responses. CBT can help with anger, but suggesting an alternative implies the client’s coping strategy is a problem, when it’s actually a healthy, adaptive one. B and C also redirect the client away from a strategy that’s working. Exercise doesn’t treat anger problems on its own, and the social worker can keep exploring what drives the anger, but the best response to what the client shared is to recognize and reinforce it.

Strategy takeaway: Know which defense mechanisms are considered mature, such as sublimation, humor, and altruism. When a client describes a healthy coping strategy, the best response is often to recognize and reinforce it.

Question 5: Single-subject design

Correct answer: D) The period during which the subject’s behavior or condition is observed without any intervention

Only 63% answered correctly (58 of 92 test records).

Rationale: In a single-subject design, the baseline (the “A” phase) is the period when the behavior or condition is measured repeatedly before the intervention begins. The intervention phase (the “B” phase) follows. Comparing the two shows whether the target behavior changed after the intervention started.

Why the other answers are tempting: The most popular wrong answer, A (the initial phase where the intervention is first applied), drew 23% of responses. It confuses the baseline with the start of the intervention phase. C (a control group) is a feature of group designs, not single-subject designs, where the client serves as their own comparison. A baseline involves repeated measurements over time before anything changes.

Strategy takeaway: Picture an A–B graph: A = baseline, B = intervention. Stable, repeated baseline measurements make it easier to tell whether the intervention made a difference.

3) How to Handle Questions Like These on the New ASWB Exam

The new ASWB exam, which launched on August 3, 2026, puts more emphasis on applying knowledge and reasoning. That means more questions where more than one answer sounds good. These habits help:

1. Read the last sentence first so you know exactly what’s being asked.
2. Match definitions precisely. On concept questions, the right answer fits the definition, not just “good practice.”
3. Watch for absolute words like “all,” “always,” and “never,” in the stem and in the answers.
4. Assess before acting when you don’t have enough information, unless there’s an immediate safety concern.
5. Review every rationale, including questions you got right, to make sure your reasoning matches.
