When someone reaches out for mental health support, one of the first steps is to get evaluated, but not all evaluations are the same. The two people most often confuse are a psychiatric evaluation, done by a psychiatrist or a psychiatric mental health nurse practitioner (PMHNP), and a full psychological evaluation, done by a psychologist. Both aim to understand your mental health, but they differ in who performs them, what they include, how long they take, and what they are for.
The short answer: a psychiatric evaluation is a clinical assessment by a prescriber, designed to reach a diagnosis and start treatment, usually in a single 60-minute visit. A psychological evaluation is standardized testing by a psychologist, designed to measure how you think, learn, and function, usually over several sessions, with a written report at the end.
| Psychiatric evaluation | Full psychological evaluation | |
|---|---|---|
| Who performs it | Psychiatrist (MD/DO) or psychiatric nurse practitioner (PMHNP) | Licensed psychologist (PhD or PsyD) |
| Main purpose | Diagnose and begin treatment | Measure cognitive, emotional, and behavioral functioning; document for school, legal, or diagnostic purposes |
| What it includes | Clinical interview, mental status exam, review of medications and medical history, labs when needed | Standardized tests (IQ, memory, attention, executive function, personality, emotional functioning), behavioral observation, collateral input |
| How long | About 60 minutes, sometimes a second visit | Several hours across multiple sessions, plus scoring and report writing |
| What you get | A working diagnosis and a treatment plan; prescriptions if appropriate | A detailed written report with scores, diagnostic impressions, and recommendations |
| Can they prescribe? | Yes | No (psychologists do not prescribe in Virginia) |
| Best for | Depression, anxiety, ADHD, bipolar disorder, PTSD, and most conditions where treatment is the goal | Learning disabilities, autism evaluations, IEP/504 documentation, court-ordered assessments, unclear or complex presentations |
A psychiatric evaluation is typically the first step with a psychiatrist or a PMHNP. It is comprehensive but focused: the goal is to understand your current mental health and guide treatment.
What it includes
How long it takes: at South Chesapeake Psychiatry, the initial evaluation is 60 minutes; some situations, such as a possible bipolar or ADHD diagnosis, take a second visit.
The goal: a personalized treatment plan that addresses your immediate needs and sets you on a path toward feeling better.
A psychological evaluation is a much more in-depth process, conducted by a licensed psychologist (PhD or PsyD). It is used when there is a need for diagnostic clarification, formal documentation, or educational accommodations.
What it includes
How long it takes: several hours across multiple sessions, plus time for scoring and report writing.
The goal: a deep, data-driven understanding of psychological functioning, often used for ADHD or learning disability diagnoses, autism spectrum evaluations, court-ordered assessments, school IEP or 504 plans, and complex or unclear presentations.
For most people, the psychiatric evaluation comes first. If your goal is treatment, especially treatment that may involve medication, start with a prescriber; a PMHNP or psychiatrist can diagnose and begin treating depression, anxiety, ADHD, bipolar disorder, PTSD, and most other conditions in that first hour, and will tell you if testing is needed.
Go straight to a psychologist for a full evaluation when a school, court, employer, or disability program requires formal documentation, when a learning disability or autism is the primary question, or when previous treatment has not worked and the diagnosis itself is in doubt. The two are not either/or: a psychiatric provider frequently refers for testing, and a psychologist's report often comes back to the prescriber to guide medication.
Yes. ADHD is a clinical diagnosis made from history, symptoms across settings, and, when possible, rating scales completed by a parent, teacher, or partner. A psychiatric evaluation can diagnose and treat ADHD in children, teens, and adults without formal testing. Psychological testing becomes useful when a school requires it for accommodations, when a learning disability may be present alongside ADHD, or when the picture is complicated by other conditions. Our ADHD page describes how we evaluate it.
A psychiatric evaluation at South Chesapeake Psychiatry is $300, self-pay, for the 60-minute initial visit, with a superbill available for out-of-network reimbursement. A full psychological evaluation is billed by the psychologist's office, varies widely with the number of tests involved, and is sometimes partly covered by insurance when it is medically necessary; ask the testing practice for an estimate and a benefits check before scheduling.
Both types of assessment are valuable, and they serve different purposes. If you are looking for treatment, a psychiatric evaluation is usually the place to start. If you or your child needs formal testing for school, legal, or diagnostic clarification, a full psychological evaluation may be the right tool, and we can refer you.
