Neuropsychological testing is performed by a clinical neuropsychologist, a licensed psychologist with specialized training in how the brain affects thinking, behavior, and emotions. In some cases, a trained technician called a psychometrist administers the actual tests under the neuropsychologist’s supervision. Understanding who’s involved in the process, and how their roles differ from other professionals who assess brain function, can help you know what to expect.
What a Clinical Neuropsychologist Is
A clinical neuropsychologist holds a doctoral degree in psychology (either a PhD or PsyD) from an accredited program and is licensed to practice independently. But the degree alone isn’t enough. Neuropsychologists complete additional years of supervised training focused specifically on brain-behavior relationships, learning to connect patterns in test performance to specific cognitive strengths and weaknesses.
The most rigorous credential in the field is board certification through the American Board of Clinical Neuropsychology (ABCN), which is part of the American Board of Professional Psychology. This certification process evaluates both scientific knowledge and clinical skill. Earning it requires documented training across eight core knowledge areas, which typically span graduate coursework, supervised clinical hours, and postdoctoral fellowship work. Not every practicing neuropsychologist is board-certified, but the credential signals a high level of demonstrated competence.
The Role of the Psychometrist
If you go in for neuropsychological testing, you may spend most of your time with a psychometrist rather than the neuropsychologist directly. A psychometrist is a trained technician whose primary job is administering and scoring the battery of tests. They function as an extension of the neuropsychologist, following standardized procedures so the results are reliable and consistent.
The average testing session runs about five hours per patient, and the psychometrist handles that hands-on work: giving instructions, timing tasks, recording responses, and noting behavioral observations like frustration or fatigue. After the session, they score each test using norm tables, verify accuracy, and compile the results into a file. The neuropsychologist then reviews everything, interprets the patterns, integrates other medical information, and writes the final report with diagnostic conclusions and recommendations. So while the psychometrist does much of the visible work during testing day, the clinical judgment comes from the neuropsychologist.
How Neuropsychologists Differ From Neurologists
These two specialists both deal with brain function, but they approach it from opposite directions. A neurologist is a medical doctor who focuses on the physical structures and systems of the nervous system. They diagnose and treat conditions using tools like MRIs, medications, and physical exams. Their concern is largely what’s happening in the brain physically: a lesion, inflammation, nerve damage, blood flow problems.
A neuropsychologist focuses on the cognitive and behavioral side. Rather than imaging the brain, they measure how it performs: how well you remember a story after a delay, how quickly you process visual information, whether you can shift between mental tasks efficiently. They don’t prescribe medication. Instead, their evaluation maps out specific patterns of cognitive strength and weakness that point toward a diagnosis and guide treatment planning. In many cases, a neurologist and neuropsychologist work as complements. The neurologist identifies or suspects a condition, and the neuropsychologist quantifies its cognitive impact.
How School Psychologists Compare
Parents searching for answers about a child’s learning difficulties often encounter two paths: a psychoeducational evaluation through the school and a neuropsychological evaluation from a private specialist. These are not the same thing.
A psychoeducational evaluation, typically performed by a school psychologist, assesses a child’s intelligence and academic achievement to identify learning difficulties in the classroom. It answers “what is happening” and guides accommodations like extra time on tests or modified assignments. These evaluations are narrower in scope and generally take less time to administer.
A neuropsychological evaluation goes deeper. It formally assesses specific domains of cognitive functioning, including attention, memory, executive functioning, language, and visuospatial reasoning. This allows the neuropsychologist to explain “why” the difficulties are occurring by identifying the underlying brain-based processes involved. For children with complex profiles involving attention disorders, language-based learning disabilities, or social-emotional difficulties layered on top of academic struggles, the broader scope of neuropsychological testing often provides the level of detail needed for accurate diagnosis and targeted intervention.
Pediatric Neuropsychologists
Children aren’t just small adults when it comes to brain function. Their brains are still developing, and the way cognitive problems show up in a seven-year-old looks very different from how they present in a 60-year-old. Pediatric neuropsychologists complete their doctoral training in clinical psychology, clinical neuropsychology, pediatric psychology, or school psychology, followed by fellowship training specifically focused on children.
These specialists evaluate a wide range of developmental and medical conditions. In academic medical centers, pediatric neuropsychologists often work with children who have brain-related effects from cancer treatment, sickle cell disease, traumatic brain injuries, epilepsy, and genetic conditions. The cognitive difficulties they assess commonly involve attention, executive functioning (the brain’s ability to plan, organize, and self-regulate), memory, visuospatial reasoning, and psychosocial adjustment. Their recommendations typically address not just clinical treatment but also school accommodations, helping bridge the gap between a medical diagnosis and what a child needs in the classroom.
Geriatric Neuropsychologists
On the other end of the age spectrum, neuropsychologists play a critical role in evaluating cognitive decline in older adults. Neuropsychological testing is considered the most sensitive method for detecting early or mild dementia, often picking up subtle changes before they’re obvious in daily life or visible on brain imaging. This early detection matters because some causes of cognitive impairment in older adults are reversible, including medication side effects, depression, thyroid problems, and vitamin deficiencies.
When testing does confirm a dementia diagnosis, the neuropsychologist’s role extends beyond the test results. They help frame the diagnosis for the patient and family, provide information about what to expect, and recommend psychological and psychosocial interventions. While there’s no cure for Alzheimer’s disease or vascular dementia, treatments in the psychological domain can significantly reduce suffering and improve quality of life for both patients and caregivers.
Where Testing Takes Place
Neuropsychological testing happens across a variety of settings. Academic medical centers and hospital-affiliated clinics are common, particularly for complex medical cases. Many neuropsychologists also work in private practice, where they see patients referred for everything from ADHD evaluations to post-concussion assessments. Some are embedded in VA hospitals, rehabilitation centers, or specialty clinics.
There’s also a forensic side to the field. Neuropsychologists conduct evaluations for legal cases involving civil disputes, criminal proceedings, and disability claims. At some centers, this includes assessments related to the NFL concussion settlement program. In forensic work, the neuropsychologist may be asked to provide depositions or testify at trial about a person’s cognitive functioning.
Who Refers You for Testing
You typically don’t schedule neuropsychological testing on your own, though some private practices do accept self-referrals. More commonly, a referral comes from your primary care provider, a neurologist, a geriatrician, or another specialist who wants a more detailed picture of your cognitive functioning than a brief office screening can provide. Psychiatrists, rehabilitation physicians, and sometimes attorneys handling injury or disability cases also refer patients for evaluation. If you think you could benefit from testing but haven’t been referred, asking your primary care doctor is the most straightforward starting point.
