Psychological Testing & ADHD Assessments
ADHD and Psychological Testing for Children, Teens, and Adults
Understanding how you or your child thinks, learns, and functions can make a meaningful difference at school, work, in sports, and in everyday life. At Achieve Performance Psychology, we provide comprehensive ADHD assessments and psychological testing for children (ages 7+), adolescents, and adults.
Led by Dr. Katie Peterson, a licensed psychologist, our assessment services are designed to provide clarity, identify strengths and challenges, and offer practical recommendations for moving forward. We take an individualized approach to testing, helping each person and family better understand their needs and next steps.
Who We Serve
-
Athletes face unique demands both in competition and in everyday life. When challenges with attention, learning, emotional regulation, or mental health begin to interfere with school, sport, or daily functioning, psychological testing can help provide answers. Our comprehensive assessments help athletes and families better understand these challenges and identify appropriate next steps.
ADHD: An ADHD diagnosis can explain difficulties with focus during practice, following complex game plans, or managing emotions under pressure. Our testing helps athletes and their families understand these challenges and provides a clear path to developing effective coping strategies.
Learning Disabilities: A learning disability may affect an athlete's ability to absorb coaching instructions, study complex playbooks, or keep up with academic demands. A diagnosis can lead to crucial academic and athletic accommodations, allowing you to excel on and off the field.
Differential Diagnoses and Diagnostic Clarification: Performance on the field or court isn't just physical—it's deeply connected to mental health. Because some mental health conditions share common symptoms (e.g., inattention, poor focus, or irritability can be seen in ADHD, anxiety, depression, and trauma), a simple observation may not be enough. A psychological assessment using standardized tests can provide diagnostic clarification by helping to distinguish subtle differences and identify the primary causes of an athlete's challenges. This clarification is not just for a label, but a roadmap to effective treatment.
Our comprehensive assessments and recommendations are tailored to the unique demands of athletes, helping you transform potential challenges into personal strengths.

Difficulties with attention, organization, memory, or completing tasks can affect both your professional and personal life. For some adults, these challenges have been present for years without a clear explanation. Psychological testing can help identify ADHD, learning disabilities, and other factors that may be contributing to these difficulties. At Achieve Performance Psychology, we provide comprehensive assessments to help adults better, understand how they think, learn, and function.
ADHD: For many adults, ADHD can show up as difficulty staying organized, meeting deadlines, maintaining focus, or following through on tasks. Some have experienced these challenges since childhood without ever receiving a diagnosis. A comprehensive ADHD assessment can help clarify whether ADHD or other factors are contributing to these difficulties and provide recommendations for support at work and in everyday life.
Learning Disabilities: Some adults have spent years struggling with reading, writing, processing information, or learning new material without understanding why. Psychological testing can help identify learning disabilities, such as dyslexia, and provide a clearer picture of an individual's strengths and challenges. Results can also guide recommendations for workplace accommodations and strategies to support everyday functioning.
Differential Diagnoses and Diagnostic Clarification: Difficulties with attention, concentration, organization, or memory are not always caused by ADHD. Anxiety, depression, and other psychological concerns can sometimes present with similar symptoms. A comprehensive psychological assessment can help distinguish between these conditions and provide greater clarity about what may be contributing to an individual's challenges.
Our assessments include individualized recommendations to help adults better understand their needs and identify appropriate next steps for treatment and support.

When your child is struggling with attention, learning, organization, or behavior, it can be difficult to know what is contributing to those challenges. Psychological testing can help provide answers. At Achieve Performance Psychology, we offer comprehensive ADHD assessments, learning disability evaluations, and psychological testing for children and adolescents to help families better understand their child's needs and identify appropriate next steps.
ADHD: A diagnosis of ADHD can explain why a student might struggle to stay organized, have difficulty completing homework, or be easily distracted in class. Our evaluations can help identify these challenges and provide recommendations that families may use when discussing appropriate school supports and accommodations, like extended time on tests, preferential seating, and other adjustments that create a supportive learning environment.
Learning Disabilities: A learning disability can make reading, writing, or math feel incredibly difficult, despite a student's best efforts. We can identify specific learning disabilities such as dyslexia, dysgraphia, or dyscalculia. Our evaluations can help identify specific learning disabilities and provide recommendations to guide conversations with schools about appropriate academic supports, including potential eligibility for an IEP or 504 Plan.
Differential Diagnoses and Diagnostic Clarification: Sustained academic performance isn't just about effort and intelligence—it's deeply connected to mental clarity, executive function, and resilience. Because some academic or mental health challenges share common symptoms (e.g., difficulty focusing, poor concentration, chronic procrastination, or irritability can be seen in ADHD, generalized anxiety, burnout, and depression), simple observation is sometimes insufficient. A comprehensive psychological assessment using standardized, objective tests can provide diagnostic clarification by helping to distinguish subtle differences and identify the primary root causes of a student’s struggles. This clarification is not just for a label, but a roadmap to effective treatment and academic success.
Testing gives students and parents the clarity and confidence to advocate for their needs. It transforms school from a source of frustration into a place where your child can truly thrive and feel understood.

Then, we have two to three in-person testing sessions held over three-hour testing blocks. These sessions are scheduled over multiple days to minimize fatigue.
Finally, two to three weeks after testing, we have a feedback session to discuss your results, any diagnoses, and our recommendations for maximizing the potential in your unique mind. You receive a final report shortly after our meeting.

The total fee for the psychological assessment is $2,500.
$1000 is due at the initial intake session.
The remaining $1500 is due at the feedback session.
This total fee encompasses all fees associated with the assessment including the intake and feedback sessions, testing materials, scoring and interpretation of the assessment battery, the final report, and the report writing time. Payment is required as outlined above.
