ADHD Evaluations for Adults
Get answers from a team with decades of diagnostic and educational expertise. Diagnostic Learning Services provides comprehensive Learning Disability and ADHD evaluations for adults. Our trusted documentation is accepted by employers, certification boards, and 550+ colleges and universities nationwide.
For more than two decades, our trusted approach has helped thousands nationwide find clarity, understanding, and a path forward.
Why Our Approach Works
At Diagnostic Learning Services, we never evaluate a single skill in isolation. Our adult psychoeducational assessments connect the dots between reading, writing, math, attention, memory, executive functioning, and processing to ensure accurate diagnoses and practical next steps.
Whether your goal is college accommodations, standardized testing documentation, workplace support, or simply understanding lifelong challenges, our goal is to give you clear answers and a plan that leads to lasting success.
Comprehensive Psychoeducational Evaluations for Adults
Our adult evaluations identify the underlying causes of learning, attention, or processing difficulties that can affect performance in professional or daily life settings.
Whether you’ve struggled for years—or you’re noticing challenges at work—our assessments are designed to determine whether difficulties stem from:
• A specific learning disability (dyslexia, dysgraphia, dyscalculia)
• ADHD and executive functioning challenges
• Processing, memory, or attention differences that affect learning and productivity
Each evaluation provides more than a diagnosis. You gain insight, self-understanding, and evidence-based recommendations you can use immediately.
Results may support documentation needs for:
• Standardized testing accommodations (GRE, LSAT, MCAT, NCLEX, and more)
• Workplace accommodations under ADA guidelines
What Our Assessments Measure
Our comprehensive evaluation examines key areas of learning and cognition, including:
Learning Disabilities
Identifying dyslexia (reading), dysgraphia (writing), and dyscalculia (math) to clarify academic and functional needs.
Attention and Focus
Evaluating for adult ADHD and attention-related difficulties that affect performance.
Visual and Auditory Processing
Understanding how the brain interprets information through sight and sound.
Problem-Solving & Processing Speed
Measuring reasoning, cognitive flexibility, and how efficiently information is understood.
Memory
Assessing short-term and long-term memory essential for retention and comprehension.
Academic Skills
Measuring reading, writing, and math skills to identify patterns that may indicate a learning disability.
What to Expect on the Day of Testing
During your evaluation, you’ll meet one-on-one with an assessment specialist and complete structured, interactive tasks that measure attention, processing, memory, executive function, and reasoning—building a complete picture of how you learn.
Every evaluation is personalized to your goals—whether you are:
• requesting college accommodations,
• preparing for professional or graduate exams, or
• seeking clarity about lifelong learning challenges and productivity difficulties.
After the Evaluation: Creating a “Road Map” for Success
Our goal is not only to provide diagnostic clarity, but to equip you with the knowledge and strategies to move forward.
Within 10 to 14 business days of your evaluation, you’ll meet with a Diagnostic Learning Services Director to review the results. During this meeting, the director explains findings and recommendations in clear, practical terms.
Your written report becomes a valuable tool you can use to:
• share documentation with professors or employers,
• support standardized testing accommodation requests, and
• build a personalized plan for ongoing success.
Let us help you become the expert in your own success—at work and beyond.
Tip:
Follow-up appointments are an excellent time to ask detailed questions and clarify recommendations.
Based on the assessment results we may recommend:
• Requesting workplace accommodations: tailored support such as extended time, reduced distractions, written instructions, or alternative communication methods.
• Exploring specialized interventions: targeted strategies for reading, writing, math, or executive functioning.
• Using assistive technology: voice-to-text, text-to-speech, organizational systems, and productivity tools.
• Accessing external resources and support networks: coaching, counseling, support groups, or academic success services.
What is ADHD
ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects attention, organization, self-control, and executive functioning. While ADHD often begins in childhood, many adults discover it later—after years of feeling disorganized, overwhelmed, or “always behind.”
ADHD is not caused by poor parenting or lack of effort. It is linked to brain-based differences and genetics. With the right strategies, supports, and accommodations, adults with ADHD often see major improvements in productivity, emotional regulation, and quality of life.
Did you know?
It’s never too late to thrive. A diagnosis brings clarity—not limitation.
There are 3 types of ADHD
While once labeled as ADD vs. ADHD, today ADHD is the recognized diagnosis and includes three presentation types:
Predominantly Inattentive Type
Misses details / careless mistakes
Difficulty sustaining attention
Seems not to listen
Doesn’t follow through on instructions
Disorganization
Avoids sustained mental effort
Loses things
Easily distracted
Forgetful in daily activities
Predominantly Hyperactive/Impulsive Type
Fidgets/squirms
Difficulty staying seated
Restless
Difficulty being quiet
“Driven by a motor”
Talks excessively
Blurts answers
Difficulty waiting
Interrupts or intrudes
Combined Type
Meets criteria for both inattentive and hyperactive/impulsive patterns.
Note:
Past evaluations often relied solely on symptom surveys, which could lead to misdiagnoses. Our approach uses a comprehensive process for accurate results.
ADHD Evaluation Options for Adults
Diagnostic Learning Services offers two evaluation options for adults seeking ADHD testing:
Comprehensive ADHD Evaluation (For Accommodations + Treatment)
This in-depth adult ADHD evaluation examines attention, executive functioning, impulsivity, hyperactivity, processing speed, and cognitive functioning. It also includes screening for underlying mental health factors such as anxiety or depression.
Duration: approximately 3.5–4 hours
Includes subjective + objective measures
Provides documentation for:
• ADHD treatment support
• College accommodations
• Standardized testing accommodations (GRE, LSAT, MCAT, licensing exams)
Note:
This is the best option if you need formal documentation for accommodations.
Focused ADHD Evaluation (For Treatment Only)
This evaluation specifically assesses attention and focus-related processing skills using subjective and objective measures.
Duration: approximately 1.5–2 hours
Mostly online with face-to-face interaction
Includes symptom inventories that may be sent to family or close contacts
Provides documentation for ADHD treatment, but does not meet accommodation requirements.
Note:
This option is for diagnosis and treatment purposes only.
The Qb Check
As part of both adult ADHD evaluation options, we may use the Qb Check—an FDA-approved computer-based assessment that measures attention, impulsivity, and activity levels in real time.
By combining Qb Check results with symptom surveys, behavioral observations, and additional assessment tools, we provide a more objective and accurate understanding of how ADHD may be affecting you.
Why We Look at the Whole Picture
Adults often experience overlapping symptoms across learning disabilities, attention challenges, and processing differences. Our comprehensive approach evaluates reading, writing, math, attention, memory, and processing to ensure the most accurate diagnosis and support plan.
FAQs
Find answers to common questions about our diagnostic services and processes.
What is a 'psycho-educational evaluation'?
A psycho-educational evaluation is a comprehensive assessment designed to provide a clear, detailed picture of how someone learns, processes, and retains information. It involves tests that measure cognitive abilities (like memory, problem-solving, and reasoning skills), academic achievement (reading, math, and writing performance), or attention difficulties.
These assessments are crucial to help identify learning disabilities, ADHD, or other learning-related challenges while providing clear documentation and a detailed roadmap of an individual’s strengths and areas of need. This information helps parents, educators, or employers understand why someone may be struggling and what types of supports, accommodations, or interventions will be most effective. Without a comprehensive evaluation, it can be difficult to accurately pinpoint the root of these challenges or how to provide meaningful, effective support moving forward.
Will schools or colleges accept your evaluations for accommodations?
Yes, absolutely. Our comprehensive reports are meticulously designed to meet the rigorous standards and specific documentation requirements set forth by all educational institutions and testing authorities.
Diagnostic Learning is committed to staying up-to-date on the latest evolving guidelines, laws, and best practices across the educational and testing landscapes. The documentation you receive from us will be current, compliant, and universally accepted, giving you peace of mind and reducing the stress of the accommodations process.
How soon can we schedule testing, and when will we get results?
Once you’re ready to move forward, appointments are typically scheduled within 10–14 days of your call with us, depending on availability.
After testing is completed, our team needs approximately 10–14 days to review the results and prepare a detailed evaluation report. You’ll then meet with a director for a comprehensive follow-up meeting, who will walk you through the results in clear, easy-to-understand terms and provide a personalized roadmap of recommendations and next steps.
Do you test adults, too—or just kids?
Yes! Learning differences don’t only affect children. Many adults discover later in life that they’ve been compensating for learning or attention challenges for years without answers. We test individuals of all ages, including college students and working professionals who may need documentation for academic, workplace, or professional exam accommodations.
