What you get from an ADHD evaluation
A thorough assessment can help you:
Confirm (or rule out) ADHD with evidence-based testing
Understand your unique strengths and challenges
Receive a detailed written diagnostic report
Support accommodations for school, college, standardized testing, or work (e.g., 504 Plan documentation, disability services paperwork)
ADHD can be missed — especially when you’ve been “getting by”
Many people learn to mask ADHD by overworking, compensating, or pushing through until stress, workload, or life transitions make it harder to keep up. Adults (and especially women) are often diagnosed later after years of coping
If any of this sounds familiar, you’re not alone:
You work twice as hard to get “normal” results
You feel chronically behind, overwhelmed, or mentally exhausted
You’ve been told you’re smart—but your performance doesn’t match your effort
You worry others think you’re careless, lazy, or not trying
An accurate diagnosis matters because it gives you language, data, and a plan—so you can stop guessing and start advocating.
ADHD Testing Services We Offer
-
Understanding whether your child has ADHD can change the trajectory of their education and mental health. We evaluate children beginning at age 6.
You’ll receive a clear diagnosis (when appropriate) and a report that can support school planning and accommodations such as a 504 Plan.
-
If focus, attention, motivation, or organization issues are affecting school performance or social functioning, a comprehensive evaluation can provide clarity.
Our reports can support high school accommodations and documentation for standardized testing accommodations when needed
-
If you suspect ADHD was missed earlier—or you’ve always had to “work harder than everyone else”—a thorough adult ADHD assessment can help you understand your executive functioning profile and build strategies that actually fit your brain.
We provide a detailed report to support accommodations for college, graduate school, or workplace needs.
What is ADHD?
ADHD (Attention-Deficit/Hyperactivity Disorder) is a common neurodevelopmental condition that affects attention, executive function, and self-control. A professional ADHD assessment is essential to receive an accurate diagnosis in Los Angeles and access testing accommodations for school, work, and standardized exams
ADHD is a neurological diagnosis, which means that something different is happening in your brain. That difference is not a bad thing, but it can feel like a bad thing when you aren’t sure what is happening to you. Did you know that about 8% of children and 2.5% of adults have ADHD? It’s typically identified in school-aged children, but sometimes teachers, parents, and mentors miss it.
The good news? It is diagnosable and you can get treatment. You just need the right testing in order to get a real ADHD diagnosis. We’ve become mavens at providing the best ADHD assessments so that you can finally get focused. Many students who receive an ADHD diagnosis later pursue testing accommodations for exams like the SAT or ACT.
In your ADHD assessment, we test your neurological functioning and collect meaningful data about your educational history. Why? Because we want to write a report that helps you advocate for yourself at your school and/or work. Our reports include all the necessary information for you to advocate for your needs when you submit them to your work or school’s Disabilities Office. You can’t get testing accommodations unless you have one of these reports.
What’s included in our ADHD evaluations?
Our ADHD assessments are designed to measure the skills that ADHD most commonly impacts and to differentiate ADHD from other conditions that can look similar.
Your evaluation may include:
Comprehensive clinical interview + developmental/educational history
Standardized measures of attention, focus, and executive functioning
Data-informed differential diagnosis (e.g., ADHD vs anxiety, depression, trauma-related symptoms, or learning disorders)
A written report structured for advocacy with schools and workplaces
Why formal testing (not just screening) matters?
Some providers offer an “informal” ADHD diagnosis based on an interview alone. However, accommodations for school, standardized testing, and many workplaces typically require objective testing data and a formal written report.
We focus on producing the kind of documentation that is:
Clear
Evidence-based
Easy to use for accommodations and next steps
ADHD (Attention-Deficit/Hyperactivity Disorder) is a common neurodevelopmental condition that affects focus, attention, and self-control. Many people live with undiagnosed ADHD, which can impact school, work, relationships, and daily life. A professional ADHD assessment can help you:
Understand your unique challenges and strengths
Access academic or workplace accommodations
Develop effective strategies for success, including customized executive functioning hacks to keep you on track
Organizing your most important life tasks in manageable ways
Learning realistic skills you can use to help you stay motivated and on track (body doubling, anyone?)
Skills for assessing what is working and what tends to sabotage your focus efforts
Creating conversations to get your partner, parents, and important people on board with what you might need to function well
Improve your overall mental health, because your self-esteem has likely taken a hit from the feedback you’ve gotten over the years that you aren’t great at focusing
