Struggling With Attention, Focus, or Motivation?

​

A Comprehensive ADHD Evaluation Can Bring Clarity.

​

If attention challenges are affecting school, work, relationships, or daily functioning, a high-quality ADHD evaluation can help you finally understand what’s happening — and what to do next.

​

At Leonard Educational Evaluations, our multi-specialist team provides gold-standard ADHD testing that identifies:

  • Whether ADHD is present

  • Subtype and severity

  • Co-existing conditions

  • Why focus, planning, memory, or organization may be breaking down

  • What supports, accommodations, and strategies will help​

What an ADHD Evaluation Includes

​

1. Comprehensive Intake & Record Review

We gather background information, teacher/employer feedback, and school or medical records to tailor testing to your concerns.

​

2. Targeted Cognitive & Behavioral Testing

Including:

  • Attention & vigilance

  • Working memory

  • Processing speed

  • Executive functioning (planning, organization, inhibition, flexibility)

  • Impulse control

  • Emotional regulation

  • Academic performance patterns​

​

3. Rating Scales 

Validated ADHD and executive functioning scales compare everyday performance to age expectations.

​

4. Differential Diagnostic Review

We clarify whether symptoms are due to:

  • ADHD

  • Anxiety

  • Depression

  • Learning disabilities

  • Executive functioning disorder

  • Environmental factors

​​

5. Personalized Report & Feedback Session

You receive:

  • A clear diagnosis (if appropriate)

  • Easy-to-understand interpretation

  • Detailed interventions, accommodations, and treatment recommendations

  • Documentation for schools, colleges, and employers

We provide documentation for IEPs, 504 Plans, ADA accommodations, and college testing accommodations (SAT, ACT, GRE, LSAT, MCAT, etc.).

Why ADHD Is Often Missed or Misdiagnosed

ADHD presents differently at each developmental stage, and many bright children or high-functioning adults compensate until demands exceed their coping capacity.

Our evaluation goes beyond symptoms to assess:

  • Cognitive processes

  • Learning patterns

  • Behavioral functioning

  • Environmental and emotional factors

  • Executive functioning strengths and weaknesses

This ensures the diagnosis — or non-diagnosis — is accurate, defensible, and meaningful.

Results You Can Expect

  • Clear diagnostic answers

  • Actionable strategies for home, school, or work

  • Recommendations teachers and professors can implement immediately

  • Appropriate referrals (therapy, psychiatry, coaching)

  • Confidence in understanding how your/your child’s brain works
