The five parts of an evaluation
It starts with a call to (888) 870-7405. We ask what prompted the call and what you want the evaluation to answer, and a referral is welcome but not required. From there, testing has five parts over about two weeks.
Week 1Parts 1 to 3 happen over about a week
- 01CollateralCalls as neededMay include a call or calls between the psychologist and the referring provider, family members or both, with your permission, to understand the history and the question behind the evaluation.
- 02Initial evaluation1 hourAn hour long conversation about concerns, history and goals. Bring any past evaluations, school records, IEP or 504 plans.
- 03Testing4 to 6 hoursStandardized tasks and questionnaires, one on one with the examiner, in person in Culver City. Breaks are built in.
Week 2Usually within a week after testing
- 04Feedback session1 hourAn hour long session to go over the results, with recommendations for school, work, exams and care.
- 05Written reportYours to keepThe findings and recommendations in writing, shared with a school, doctor or testing organization only with your permission.
For a child or teen, parents take part in the initial evaluation and the feedback session. Results are scored and compared with others of the same age before the feedback session.
How to prepare
No studying is needed. The goal is to see how you think on a typical day.
- Sleep well the night before and eat a normal breakfast
- Take your usual medication unless you were told otherwise when booking
- Bring glasses or hearing aids if you use them
- Bring a snack, water and any medication taken during the day
- Bring past reports, school plans or report cards if you have them
- For a child or teen, explain that it is not a test you can fail, just puzzles and questions
On testing day
- Not pass or failMany tasks get harder until everyone misses some items. Not knowing an answer is expected.
- BreaksBreaks are built in, and you can ask for one at any time. Testing can be split across sessions.
- ComfortTell the examiner if you are tired, hungry or unwell; results are most accurate when you feel your usual self.
After testing
The written report explains the results, any diagnosis and specific recommendations for home, school, work and care. It belongs to you, or to the parents of a child or teen, and is shared with a school, college, test sponsor or doctor only with written permission. When it helps, results connect directly to therapy and family sessions at Blackburn, and psychiatric care can be arranged.
Testing day questions
What is a neuropsychological evaluation?
It is a set of standardized tests and interviews that shows how a person thinks, learns, pays attention, remembers and manages emotions. It answers a specific question, such as whether ADHD, a learning disability or autism is present, and ends with a written report and a feedback session.
How long does a neuropsychological evaluation take?
Usually about two weeks from the first appointment to feedback and the written report. Collateral calls, a one hour initial evaluation and 4 to 6 hours of testing happen over about a week. The one hour feedback session and the written report usually follow within a week after that.
How long is the testing day?
The testing itself takes 4 to 6 hours, one on one with the examiner, with breaks built in. Bring a snack and water. Our team confirms the schedule with you when you book.
Who is involved besides the person being tested?
With your permission, the psychologist may have a call or calls with the referring provider, such as a doctor or therapist, and with family members, to understand the history and the question. This is called collateral, and it happens in the first week. For a child or teen, parents or guardians also take part.
Do I need to study or prepare?
No studying is needed, and studying would not help. The best preparation is a good night of sleep, a normal breakfast, your usual medication unless you are told otherwise, and glasses or hearing aids if you use them.
Can you fail a neuropsych test?
No. There is no pass or fail. Many tasks are designed to get harder until everyone misses some items, so it is normal not to know every answer. Just do your best.
Should my child or teen take their ADHD medication on testing day?
Ask when you book. The answer depends on the question the evaluation is meant to answer, and you will be told what to do before testing day. Do not stop any medication on your own.
What should we bring?
Glasses or hearing aids, any medication taken during the day, a snack and water, a list of current medications, and past reports, school plans or report cards if you have them.
Are breaks allowed?
Yes. Breaks are built in, and you can ask for one at any time. Testing can be split across more than one session when that works better.
Where does testing happen?
Testing sessions take place in person in Culver City.
Who receives the report?
The report goes to you, or to the parents of a child or teen. It is shared with a school, college, test sponsor or doctor only with written permission.
What happens at the feedback session?
A clinician goes over the results in plain language, explains any diagnosis, walks through the recommendations and answers questions. For a child or teen, parents attend, and the student may join for part of it.
Do I need a referral?
No. Referrals from doctors, therapists and schools are welcome but not required. Anyone can call (888) 870-7405 to book.
