When cognitive limitations are suspected, the social worker's first responsibility is to assess — not to act on assumptions. A neuropsychological evaluation is the tool that makes assessment possible.
A neuropsychological evaluation is a comprehensive, structured assessment of how the brain is functioning. It is administered by a neuropsychologist — a psychologist with specialized training in brain-behavior relationships — and typically takes several hours to complete. Unlike a brief cognitive screening, which flags whether a problem may exist, a neuropsychological evaluation is designed to characterize the problem in detail: what is affected, how severely, and what it means for the person's ability to function in daily life.
The evaluation covers multiple domains of cognitive functioning through a combination of standardized tests, structured tasks, and clinical interview. Commonly assessed areas include:
Memory — both the ability to learn new information (encoding) and to retrieve it later (recall). Tasks might involve repeating a word list or story immediately and again after a delay.
Attention and concentration — the ability to focus, sustain attention over time, and resist distraction. Tasks might include repeating number sequences forward and backward or tracking patterns.
Executive functioning — higher-order skills including planning, problem-solving, cognitive flexibility, and impulse control. These are critical for managing finances, following through on multi-step tasks, and making sound decisions. A client with executive functioning deficits may appear to understand something in the moment but struggle to apply it independently.
Language — the ability to understand and express information, name objects, follow directions, and read or write at a functional level.
Visuospatial ability — the capacity to perceive and interpret visual information and spatial relationships. Tasks might involve copying a complex figure or assembling visual patterns.
Processing speed — how quickly a person can take in and respond to information, which affects performance across nearly every other domain.
Intellectual functioning — an estimate of overall cognitive ability, which provides context for interpreting the rest of the results.
The evaluation also typically includes measures of mood and psychological functioning, since depression and anxiety can significantly affect cognitive performance and need to be accounted for in the interpretation.
The results don't just identify whether a problem exists — they describe its functional impact. A person can score adequately on a memory test and still lack the capacity to manage finances, recognize when someone is taking advantage of them, or make decisions that serve their own interests. The evaluation answers a specific functional question: what can this person do independently, and where do they need support?
That answer shapes everything that follows. Depending on the findings, appropriate next steps might include arranging a representative payee, involving Adult Protective Services, pursuing a guardianship evaluation, modifying a treatment plan, or connecting the client with community supports. None of those interventions should precede the evaluation — because without it, the social worker is acting on suspicion rather than evidence.
Neuropsychological evaluation questions test whether you recognize that assessment precedes intervention. This is one of the most consistently tested principles on the ASWB exam — and one of the most common sources of wrong answers.
When a question describes a client with suspected cognitive limitations, the answer choices will typically offer a mix of assessment and intervention options. The interventions may all be reasonable — arranging a representative payee, contacting Adult Protective Services, initiating a guardianship proceeding, educating the client about financial management. The trap is choosing one of those actions before the cognitive limitations have been formally established.
The ASWB rewards the social worker who pauses before acting. Suspicion is not confirmation. Observation is not diagnosis. Until the nature and extent of the cognitive limitations are understood, the social worker doesn't have the information needed to determine what intervention, if any, is appropriate — or what level of restriction on the client's autonomy is justified.
This matters especially in questions involving vulnerable adults, because the wrong answer often looks protective. Contacting APS or arranging a representative payee can feel like the responsible choice. But those actions carry real consequences for a client's autonomy and legal standing. The exam expects you to treat protective intervention as something that requires an evidentiary basis — and a neuropsychological evaluation is how you get one.
Watch also for questions where a cognitive screening has already been completed and results are abnormal. In that context, a neuropsychological referral may itself be the assessment step. The principle is the same: move toward greater clarity before acting, and match the level of intervention to what is actually known.
