Diagnostic Assessments for
Attention-Deficit/Hyperactivity Disorder (ADHD)

What is Attention-Deficit/Hyperactivity Disorder (ADHD)?

ADHD is one of the most common neurodevelopmental disorders, with an estimated 1 in 10 school-aged children affected. Common characteristics of ADHD include:

  • Difficulty completing a task before starting another
  • Trouble concentrating
  • Forgetfulness
  • Fidgeting or restlessness

ADHD presents in a few variations:

  • Inattentive type
  • Hyperactive/Impulsive type
  • Combined type

Kids and teens with ADHD can struggle with daily life skills (organizing, planning, working memory, attention), which can negatively impact their academics and family life. Their symptoms may also affect their friendships and social success. Without proper diagnosis, kids and teens with ADHD have a greater risk of developing anxiety, depression, or substance abuse.

ADHD does not look the same for everyone.  Our psychologists are experts in diagnosing ADHD of all types. An evaluation is a key first step to understanding and managing your child or teen’s symptoms.

What are the symptoms of ADHD?

The tricky part about ADHD is the symptoms that makeup ADHD can be extreme examples of what we all experience as humans.  Inattentive type symptoms might include:
► Forgetfulness
► Difficulty listening
► Challenges with organization  

Hyperactivity / Impulsive or Combined type symptoms might also include:
► Impulse control problems like frequent interrupting
► Frequent, rarely-stopping physical motion and activity

Insomnia, depression, and anxiety are all more likely to co-occur for individuals with ADHD as a result of these symptoms.

How is ADHD diagnosed and treated?

What’s important to know is that we have real ways to diagnose ADHD and treatments that can work, including cognitive behaviorial therapy and medication options.  

With our assessment service, we provide Therapy Lab's targeted, science-backed approach in order to offer your family diagnostic clarity, recommendations for next steps, and documentation necessary to move forward.

Attention-deficit/hyperactivity disorder often goes undiagnosed, especially in early childhood. Symptoms can be hard to distinguish from typical behavior for kids under the age of four.
What are the benefits of testing for ADHD?

Understanding attention-deficit/hyperactivity disorder (ADHD) and how the symptoms uniquely affect your child can provide clarity about how to secure proper accommodations and how to tap into their own personal strengths to overcome their specific ADHD-related challenges.

ADHD affects an estimated 1 in 10 school-aged children.
Understand your child better

Why does your child do ____ ? Why is ____ extra challenging for them? ADHD and its accompanying unique symptoms may be the answer.

Long-term effects

Undiagnosed and untreated ADHD has been linked to later risk for anxiety and mood disorders, as well as behavioral, social, academic, and vocational problems.

Determine appropriate treatment or support

Evidence-based interventions for mental health and behavioral issues differ somewhat based on diagnosis. For example, a child with ADHD may need more individualized Cognitive Behavioral Therapy (CBT) for treatment of co-occurring anxiety than a typical child. People with ADHD may benefit from a variety of treatments including behavior therapy, social skills group, adaptive skills training, executive function coaching, medication, etc.

Access accommodations at school

Having a medical diagnosis indicates to school personnel that a professional has diagnosed your child. This may mean your child is more likely to get accommodations through an Individualized Education Plan (IEP) or at your child’s private school


ADHD evaluation has a few costs along with the benefits, and it’s good to know about these upfront. Costs to consider include the financial expense, time and energy, and possible emotional burden for you as a parent or caregiver. Fortunately, the evaluation should not be too much work for you; you’ll need to complete some questionnaires online and answer questions during an interview with your evaluator. And for children, the assessment will seem like puzzles and computer games.

What should I expect for my child’s evaluation?

Our diagnostic assessments for ADHD consist of three to four appointments including an in-person visit to our office in downtown Los Angeles, a telehealth interview, a real-world observation, and a feedback session. We aim to schedule one appointment per week, which means you should receive results about a month after your child’s first appointment.

The order of appointments is flexible, allowing your child to begin the testing process even if your family can’t get to our office in L.A. for a few weeks.

Cognitive Testing

Our Comprehensive Evaluation for ADHD evaluation includes in-person cognitive testing, that provides detailed information about your child’s learning abilities, and a computer-based measure of ADHD symptoms (e.g., impulsivity, inattention).

These assessment techniques provide an in-depth understanding of your child’s cognitive and executive functioning (planning, organizing, initiating, and regulating goal-directed behavior) and whether their pattern of abilities is consistent with ADHD.

Assessments may include:
► Differential Ability Scales™, 2nd edition (DAS™–II) Cognitive Assessment
► Behavior Rating Inventory of Executive Function (BRIEF) - Parent and Teacher Forms
► Adaptive Behavior Assessment System, 3rd Edition (ABAS-3)
► Behavior Assessment System for Children, 3rd edition (BASC-3)

Our Comprehensive Assessment includes:
► Cognitive testing (measure of learning abilities)
► Computer testing of attention
► Caregiver interview
► Child or teen interview
► Measure of ADHD-specific symptoms
► Measure of daily living skills
► Measure of emotional issues to screen for co-occurring problems like anxiety, depression, etc.
► Daycare or school observation and teacher interviews

Interview & Questionnaires

We will gather information from you, your child, and their teachers via interview and questionnaires to learn more about their early development, current behaviors, interests, executive functioning, sensory issues (difficulties with touch, taste, smell, sight, sound, movement, and balance), anxiety or mood symptoms, sleep issues, and more.

Our Comprehensive Assessment includes a brief behavioral observation of your child at their daycare or school in the LA area. Daycare or school observation allows us to see your child in a more natural setting than formal testing.

Together with your child’s daycare or school, we will schedule an appropriate time to visit, during which we can observe a variety of activities to assess your child’s participation in structured and unstructured activities. We advise that you and your child’s teacher should refrain from communicating to your child and their peers that the observation is taking place to maintain privacy and to allow for an unbiased sample of your child’s behavior.

If daycare or school observation is not possible, we may ask for other observation opportunities.


Your last appointment of the assessment process is the feedback session, during which we review results, including any diagnoses that are warranted, and discuss next steps.  

Through teacher interviews and questionnaires and our daycare or school observation, we will have gained insight into whether support or formal accommodations may be appropriate for your child in their learning environment. We can offer guidance on initiating the Individualized Education Program (IEP) or 504 Plan process should you decide to pursue these services. Further, the detailed results provided in our reports and the recommendations we provide can aid in the school’s assessment and plan development.

If we think you should consider medication management for your child, we will refer your family to appropriate medical providers who can help.

Detailed Report

A few weeks after your feedback session, we will provide a detailed report that includes assessment results, diagnoses, and recommendations. The recommendations we provide can help guide you if your child receives a diagnosis. If your child meets the criteria for ADHD, the report will include a medical diagnosis of ADHD and specify what type of ADHD your child has (e.g., combined presentation, predominantly inattentive presentation, or predominantly hyperactive-impulsive presentation).

Parents may share the report with other medical or behavioral health professionals, such as psychologists or psychotherapists, occupational therapists, speech therapists, and physical therapists. Families have used the report and accompanying medical diagnosis to qualify for treatment and to obtain special education services.


Therapy Lab Kids provides ADHD assessments for kids and teenagers, starting at $3,000. We offer a range of assessments, from basic to comprehensive, that are tailored to meet your child's individual needs. For more information on pricing, contact us.

Frequently Asked Questions

What happens if my child doesn't receive an ADHD diagnosis?

Regardless of whether your child or teen is given a diagnosis of ADHD, we are here to offer support and guidance. Should there be mental health concerns (e.g., anxiety, depression), we are likely to assess and diagnose these through our Comprehensive Assessment for ADHD. If we believe Autism Spectrum Disorder might be a more appropriate (or additional) diagnosis for your child, we can test for it for an additional fee. And if we think further neuropsychological testing is needed (e.g., for a suspected learning or intellectual disability), we can provide referrals for supplemental testing and collaborate with other providers.

Should you seek treatment related to other mental health concerns for your child or teen, we offer evidence-based therapy in person and via telehealth. Even if your child or teen does not meet full criteria for ADHD, they may still benefit from our ADHD plan to improve their executive functioning abilities. You can learn more about our therapy plans here.

Why should I choose ADHD-specific evaluation vs. neuropsychological or psycho-educational testing?

There are a number of benefits of choosing ADHD-specific evaluation over other types of testing:
► More cost-effective
► Fewer appointments or hours of testing
► Greater focus on ADHD-specific symptoms
► Resources and recommendations specific to ADHD

Our evaluators have extensive experience working with neurodiverse people of all ages and presentations. We have expertise in identifying ADHD and co-occurring conditions, such as anxiety, depression, trauma, and Autism Spectrum Disorder (ASD). Because there is significant symptom overlap in ADHD and other disorders, this expertise is critical for accurate diagnosis and subsequent treatment recommendations.

Additionally, neurodiversity among girls, women, and people of color has frequently been overlooked or misdiagnosed. We feel confident in our ability to identify ADHD symptoms in these populations, enabling proper diagnosis and appropriate subsequent intervention.

There is no lab test or medical diagnostic that can identify ADHD. Instead, the American Academy of Pediatrics recommends that an ADHD evaluation include information-gathering from caregivers and standardized questionnaires measuring ADHD symptoms. Our evaluations follow this recommendation and provide a picture of strengths and weaknesses associated with ADHD and their real-world implications.

What should I do if I have early concerns about ADHD for my very young child?

► Ask your pediatrician if they have concerns. Do they notice any early signs or “red flags”?

► Talk to your child’s teachers. They spend many hours a day with kids and may notice inattentiveness, impulsivity or social, communication, or behavioral differences that are noteworthy.

► Observe your child and compare them with peers (at the park, birthday parties, daycare). Is your child keeping up socially and academically? Do you notice any unusual behaviors?

► Trust your gut. Caregiver intuition is real, and you know your child best. We know that early treatment works best, so if you have any questions, it’s worth getting an expert opinion as soon as you can.
