There Is Not One Specific Test

Accurate diagnosis requires more than a quick screener or one isolated score. Diagnostic Learning Services uses a comprehensive, professional evaluation process to understand how attention, learning, and processing challenges interact—so clients receive answers they can trust and recommendations they can actually use.

Diagnostic Learning looks at the whole picture We consider history, symptoms, observations, rating scales, cognitive and academic data, processing patterns, and objective measures when appropriate so families and adults receive answers and recommendations that are clear, useful, and individualized.

Areas we evaluate

  • ADHD
  • Dyslexia
  • Dyscalculia
  • Dysgraphia
  • Visual and Auditory Processing

Why that matters

Many concerns can overlap. Attention challenges can look like learning disabilities, and processing weaknesses can affect reading, writing, math, and performance at school or work. Looking at the whole person helps us make more accurate conclusions and clearer next-step guidance.

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.

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.

The Qb Check
