Psychological Testing vs. Psychiatric Evaluation: Which One Do You Need?
Short answer
A psychiatric evaluation is a medical assessment by a psychiatrist or psychiatric nurse practitioner, usually through interviews and history, and it can lead to a diagnosis and a treatment plan that may include medicine. Psychological testing uses standardized tests, scored and interpreted by a licensed psychologist, to measure things like attention, memory, learning or personality. Testing can sharpen a diagnosis but does not lead to a prescription. Some people need one, some need both.
In crisis or thinking about suicide? Call or text 988 now (in New York City it reaches NYC 988). If you are in immediate danger, call 911.
This guide is not enough if
- You or someone else is in danger now: call or text 988, or call 911.
- Your child needs a school evaluation for special education (that request goes to your school district).
- You want a legal or forensic evaluation for court, custody or disability claims.
- You have a question about a medicine you already take: ask your prescriber.
Two evaluations that answer different questions
Someone has suggested you or your child "get evaluated," and now you are seeing two terms: psychiatric evaluation and psychological testing. They sound alike, and both can end with a diagnosis. But they are done by different professionals, use different tools and answer different questions.
A simple way to think about it: a psychiatric evaluation asks what is going on and what might help, including whether medicine makes sense. Psychological testing measures specific abilities or traits in a standardized way, so a clinician can compare results with what is typical and see strengths and weak spots more clearly.

What a psychiatric evaluation is and who does it
The American Psychiatric Association says a psychiatrist is a medical doctor (MD or DO) (opens in a new tab) who specializes in mental health. Because they are physicians, psychiatrists can order or perform medical laboratory and psychological tests, and they can prescribe. The same page says psychiatric mental health nurse practitioners are trained in diagnosis and treatment, including medication management.
The evaluation itself is mostly conversation: your current concerns and how long they have lasted, your medical and mental health history, family and social history, and the medicines you take. Diagnoses are based on criteria in the DSM. For children, AACAP says a comprehensive psychiatric evaluation usually takes a few hours over one or more visits. At Mind Body Seven, the initial evaluation typically takes two sessions for adults and two to three for children.
What you usually leave with: the clinician's impressions, a possible or working diagnosis, and recommendations, which may include therapy, medicine, more testing or follow-up. The practice's psychiatric evaluation page describes its approach.
What psychological testing is and who does it
The American Psychological Association's assessment guidelines (opens in a new tab) define a psychological test as a measurement tool that collects a structured sample of behavior and then scores and interprets it in a standardized way. The same guidelines describe assessment as a wider process that combines test results with clinical judgment, interviews, observation and reports from others.
In New York, Education Law Article 153 (opens in a new tab) defines the practice of psychology to include psychological and neuropsychological testing, and the diagnosis and treatment of mental, emotional, cognitive and learning problems. Only a person licensed or otherwise authorized under that article may use the title "psychologist." The law lets trained testing technicians give and score some standardized tests under a psychologist's supervision, but not interpret them. It also bars psychologists from prescribing drugs.
The guidelines add that psychologists typically deliver results in a written report, often with a spoken explanation. For ADHD, NIMH says a provider usually gathers history, uses standardized rating scales or checklists, and may give psychological tests of skills such as working memory and planning. Mind Body Seven's ADHD evaluations are done by licensed clinical psychologists in three steps; what happens during an ADHD test walks through them.
| Question | Psychiatric evaluation | Psychological testing |
|---|---|---|
| Who does it | A psychiatrist (MD or DO) or psychiatric nurse practitioner | A licensed psychologist; trained technicians may give and score some tests under supervision |
| Main tools | Interview, history, medical review, questionnaires, lab tests if needed | Standardized tests and rating scales, plus interview and history |
| Main question | What may be going on, and what treatment might help | How specific abilities, skills or traits compare with what is typical |
| Can it lead to a prescription | Yes, if medicine is appropriate | No; New York law bars psychologists from prescribing |
| Typical result | Impressions, a possible diagnosis and a treatment plan | Interpreted results and recommendations, often in a report |
Where neuropsychological testing fits
Neuropsychological testing is a type of psychological testing that New York law names directly. It looks closely at thinking skills. NIMH describes tests of cognitive skills such as working memory, executive functioning (planning and decision-making), visual and spatial abilities and reasoning, and says they can help identify strengths and challenges and identify or rule out possible learning disabilities.
The practice's FAQs describe a full neuropsychological evaluation as broader than a focused ADHD evaluation, covering several areas of thinking and learning. This article on neuropsychological vs. ADHD testing compares the two.
When you might need both
Many people start with one and add the other. These situations often call for both:
- Medicine is on the table, but a learning or attention problem also needs to be measured.
- A diagnosis is still unclear after a psychiatric evaluation, and the clinician wants standardized data.
- A school, college or employer asks for testing results to support accommodations.
- Symptoms overlap, such as attention problems that could relate to anxiety, sleep, mood or a learning difference.
- Treatment has not helped as expected, and the team wants to check the original picture.
Questions to ask before you book
A short call before you schedule can save you from booking the wrong kind of appointment. These questions work for either type of visit:
- What question will this evaluation answer for me or my child, and what will it not answer?
- Who will do it, and what is their license? You can look up any New York license yourself; how to check a New York mental health license shows how.
- How many appointments does it usually take, and is any part done by video?
- Will I get a written report, a feedback visit or both, and how long after the last appointment?
- If medicine might be part of the plan, who would prescribe it and how would the prescriber and tester share information?
- What records should I bring, such as earlier testing, report cards or a medicine list?
- How does billing work? For insurance, ask your plan about coverage for testing and for evaluation separately.
When neither is the right next step
If you are in crisis, an evaluation appointment is not the right first step. Call or text 988, or call 911, and see the crisis and hotline resources page.
If your symptoms may be physical, such as a new headache, a head injury or a sudden change in memory, see your primary care doctor first. If your child needs special education services, the school district evaluates at no cost; where to start a child's mental health evaluation explains that route. If you simply want to start therapy and do not have a diagnostic question, a therapy intake may be enough.

Frequently asked questions
Can a psychiatrist do psychological testing?
The American Psychiatric Association says psychiatrists, as physicians, can order or perform a full range of medical laboratory and psychological tests. Some psychiatrists use questionnaires and rating scales during an evaluation and refer to a psychologist when a full set of standardized tests is needed. New York's psychology law does not restrict people licensed to practice medicine.
Can a psychologist prescribe medication in New York?
No. New York Education Law section 7606 prohibits anyone licensed under the psychology article from prescribing or administering drugs as part of their practice. Psychologists can diagnose and provide therapy and testing. If medicine might help, they can refer you to or work with a psychiatrist, psychiatric nurse practitioner or primary care doctor who can prescribe.
Does psychological testing give you a diagnosis?
Test scores alone do not. The American Psychological Association describes assessment as combining test results with clinical judgment, interviews and other information. A licensed psychologist can then make a diagnosis, because New York law includes diagnosis in the practice of psychology. Sometimes testing shows that a different explanation fits better than the one you came in with.
Is an online quiz the same as psychological testing?
No. An online quiz is not given, scored and interpreted by a licensed professional who knows your history. Even the American Psychiatric Association's own symptom measures carry a note that they should support clinical decisions and not be the sole basis for a diagnosis. A quiz may help you put words to what you notice, which you can bring to an evaluation.
