What ADHD Assessments Can Evaluate

Whether you’re seeking answers for yourself, your child, or a teen, our ADHD assessments at McDowall provide a thorough, evidence-based assessment, without the long wait-lists. We offer ADHD assessments in-person at our Toronto, Brampton, and Mississauga clinics or virtually from the privacy of your own home.

Why ADHD Assessment Outcomes Matter

An ADHD assessment not only confirms whether ADHD is present, but also provides valuable insights into personal strengths, challenges, and any related conditions.

The outcomes guide tailored treatment plans, helping individuals access the right support, strategies, and resources to improve daily functioning and long-term well-being.

Fees & Insurance

How much does an ADHD assessment cost?

The cost depends on the depth of testing and the age of the client.

Comprehensive ADHD Assessments

  • Includes in-depth testing, a detailed written report, and personalized recommendations.
  • Suitable for children, teens, and adults with more complex needs.

Focused Adult ADHD Assessment

  • A shorter, targeted option for certain adults with straightforward needs (for example, confirming ADHD without exploring broader learning or mental health concerns).
  • Involves fewer tests and shorter appointments, making it faster and more affordable.
  • Ask us during your consultation if this approach might be right for you.

Insurance Coverage

While OHIP does not cover psychological services, many extended health plans reimburse part of the cost. We provide detailed receipts to make the insurance process as smooth as possible.
FAQ's

Frequently Asked Questions

How long does the process take?

Most ADHD assessments are completed in two sessions, with results typically ready within 2–3 weeks.

You’ll gain a clear understanding of whether your symptoms meet diagnostic criteria for ADHD, along with personalized recommendations for treatment, accommodations, and coping strategies.

Yes. Many adults seek assessment later in life after recognizing long-standing attention or organization difficulties. Adult ADHD assessments explore how symptoms impact work, relationships, and daily functioning.

Most extended health insurance plans cover psychological assessments, though coverage amounts vary. We recommend checking your benefits before booking.

You’ll receive a feedback session to review your results, discuss recommendations, and plan next steps, which may include therapy, coaching, or medical consultation.

To help us get the most accurate and complete understanding of your attention and functioning, please bring:

Any previous assessment reports (psychological, psychoeducational, or medical)

School report cards, transcripts, or workplace evaluations

Completed questionnaires (if sent before your appointment)

A list of current medications and any relevant medical notes

Your glasses or hearing aids, if used regularly

If you’re a parent bringing a child, please also bring:

Teacher feedback forms or school reports describing classroom behaviour

Copies of IEPs or support plans, if applicable

Before your appointment, try to get a good night’s rest, eat a balanced meal, and avoid caffeine or energy drinks, as these can affect concentration during testing.

This depends on the purpose of your assessment.

If the goal is to understand your natural attention and functioning, you may be asked not to take your medication that day.

If the goal is to evaluate how well your medication is working, you may be advised to take it as usual.

Your psychologist will provide specific instructions before your appointment to ensure accurate and meaningful results.
