ADHD Assessment
Comprehensive ADHD testing for children & adults
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental conditions. It affects children and adults alike, often showing up differently across the lifespan, and it frequently goes undiagnosed for years. If you or your child has been struggling with focus, organization, impulsivity, restlessness, or inconsistent performance, a comprehensive ADHD evaluation can provide the answers and direction you need.
At Mountain Peak Psychology, we offer thorough, individualized ADHD assessments grounded in the most current research and clinical best practices. We serve clients in Golden, Wheat Ridge, Denver, Steamboat Springs, and throughout Colorado.
01 — Understanding
What Is ADHD?
ADHD is a neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and/or impulsivity that interfere with functioning across multiple areas of life. There are three presentations of ADHD:
Predominantly Inattentive (previously referred to as ADD): Difficulty sustaining attention, following through on tasks, and staying organized, without significant hyperactivity.
Predominantly Hyperactive-Impulsive: Excessive physical activity, restlessness, difficulty waiting, and acting without thinking.
Combined Presentation: Significant symptoms in both areas.
ADHD is not a matter of laziness, low intelligence, or poor parenting. It is a brain-based condition with a strong genetic component, and it responds well to the right combination of support, accommodations, and, when appropriate, treatment.
02 — Who It's For
Who Might Benefit from ADHD Testing?
You might consider an ADHD evaluation if you or your child:
Has difficulty sustaining attention during tasks, conversations, or schoolwork.
Frequently loses items, misses deadlines, or forgets appointments.
Feels mentally restless or has trouble sitting still for extended periods.
Acts impulsively - speaking out of turn, making decisions without thinking, or interrupting others.
Struggles with starting tasks, especially those that feel tedious or overwhelming.
Has inconsistent performance, such as performing well sometimes but seeming to "fall apart" at others.
They have been told they're not reaching their potential despite apparent effort.
An adult who was never evaluated as a child but has always struggled with attention or organization.
Needs documentation of ADHD for academic accommodations (college, graduate school, MCAT, GRE, LSAT, etc.) or workplace accommodations.
03 — The process
What Does an ADHD Evaluation Involve?
Our ADHD assessments are comprehensive and multi-method, meaning we don't rely on any single test or questionnaire. A thorough evaluation typically includes:
Clinical Interview: An in-depth clinical interview is conducted, covering developmental history, academic and work history, current symptoms, relationships, and daily functioning. For children, a parent interview is included. This conversation provides critical context that no standardized test can capture on its own.
Cognitive Testing: Standardized tests measure core cognitive abilities to better understand executive functioning and processing.
Continuous Performance Testing: A computerized attention task (such as the CPT-3) may be administered to provide an objective measure of attention, impulsivity, and response consistency over time.
Rating Scales & Questionnaires: Validated behavior rating scales are completed by the client (and, for children, by parents and teachers). These tools capture how ADHD symptoms manifest across different environments and provide normative comparison data.
Co-Occurring Conditions: ADHD rarely exists in isolation. Our evaluation screens for, and rules out, conditions that can mimic or co-occur with ADHD, including anxiety, depression, and sleep-related concerns.
04 — The Benefits
What Are the Benefits of Getting Evaluated?
Clarity and validation — finally understanding why things have felt harder than they should.
Accurate diagnosis — distinguishing ADHD from anxiety, depression, learning disorders, and other conditions that can look similar.
Personalized recommendations — specific strategies, accommodations, and treatment options tailored to your presentation.
Academic accommodations — extended time, separate testing rooms, and other supports at school or on standardized exams.
Workplace accommodations — documentation for reasonable adjustments under the ADA.
A roadmap for treatment — whether that includes therapy, medication evaluation, coaching, or a combination.
05 — Across the Lifespan
ADHD in Adults
Many adults reach their 20s, 30s, or beyond before realizing they have ADHD. This is especially common in individuals who were high-achieving students, as their intelligence compensated for ADHD symptoms until demands outpaced their ability to cope. Adult ADHD often looks different from childhood ADHD: less hyperactivity, more internal restlessness, chronic underachievement, relationship struggles, or difficulty managing responsibilities.
An adult ADHD evaluation at Mountain Peak Psychology is just as thorough as our evaluations for children and adolescents, and the resulting report is appropriate for use with employers, healthcare providers, or higher education institutions.
