Assessment Details

The autism assessment (i.e., autism recognition and discovery) process is straightforward and transparent when you do it here. See below for details on how things will go if you proceed.

Last updated: Jan 24, 2026

Our assessment process is explained in-depth once you sign up, but here’s an overview:

  1. Sign up and send the payment (any time!)

  2. You fill out the tests and written questions online (ASAP, ideally within ~4 to 6 weeks or less)

  3. We book and then complete your interview (often within ~3 to 8 weeks of test completion, see get started for current times)

  4. I write your final report

  5. We chat to debrief your results and then I send you your final report and various resources (ASAP)

This service is for adults who are in Alberta, Nova Scotia, and New Brunswick at the time of the assessment. Our assessments specialize in identifying autism and ADHD, and we address any arising differential diagnostic information to assure comprehensive understanding of underlying issues, with the aim to provide clear insights for appropriate support.

1. Choose your assessment option and then sign up

All autism assessments here use the same foundational tests and a detailed clinical interview, differing only in report detail and some additional services in extended options. You can opt to add a thorough ADHD assessment as an additional service.

The features from the assessment “price cards” are detailed below:

Once you’ve decided between the assessment options, begin by submitting the Get Started form (when available) and submitting the payment for the assessment. Once both have been received, we will email you the tests and a receipt of payment.

2. Testing

You will be filling the tests out online, and it’s recommended that you complete the tests within 6 weeks or less, to avoid outdated data and to keep the process advancing. The entire assessment is completed in a manner that maintains confidentiality. You will also be sent an extensive list of written questions to fill out. These questions are to gather background information and to give you space to share in writing to give more details and really take your time to say things how you’d like to. Some people prefer writing to speaking, so these questions allow for that. Most of these questions require perhaps 1 to 5 sentences each, and there are approximately 60 questions.

3. Clinical Interview

After your tests are completed, we will schedule your online semi-structured clinical interview, usually within two to four weeks. During the interview, there are no expectations for your behaviour; as best as you’re able to, feel free to be yourself. There is no need to mask, maintain eye contact, engage in small talk, suppress any stims, and so on.

We spend approximately 120 to 150 minutes doing a clinical interview based on the DSM-5-TR, ADOS-2, and MIGDAS-2:

  • Online call (must be video)

  • I’ll ask any follow-ups on relevant history and family background

  • You can take approximately 10 minutes to share about what lead you to believe that you are autistic, and what is most salient about your experiences related to autism

  • I’ll ask many in-depth questions about your experiences related to the DSM-5-TR criteria for autism

    • Of course, you don’t have to answer any questions you’re not comfortable with

  • At the end, we consider possible alternate explanations for your experiences (i.e., a differential diagnosis)

4. Assessment Report

I review all collected information and prepare your assessment report, including any relevant diagnoses and accommodation letters if necessary. How promptly you receive your report will depend on the assessment option you chose.

5. Feedback/Debrief Call

We chat on a regular phone call as a debrief session (~45 to 75 minutes, as needed) to review the results of your assessment, your report, discuss findings and rationale, answer questions, and process your initial reactions to the results.

Important Notes

We only assess adults (18+) who are in Canada: in Alberta, Nova Scotia, and New Brunswick. By contacting us for this service, you are implicitly confirming that you will be in one of those places during the assessment. See the policies page for more details.

Keep in mind that this is a single clinician assessment and is best suited for cases that can be assessed by one person and diagnosed with a high degree of certainty (which is almost all people who contact me). Cases that are extremely complex are often better served in-person by a team of multiple healthcare professionals of varying backgrounds—see the FAQ for more details.

Important Note: Our assessments are intended solely for clinical and diagnostic purposes and are not intended for legal disputes. See the policy page for more information.

In-person assessments may be preferable to online assessments when assessing autism. This service (NDpsych) is generally intended for people who cannot attend an in-person assessment, for all kinds of reasons (e.g., due to sensory sensitivities, no assessment services in your area, anxiety, etc.).

  • If you are unable to communicate with us via email yourself as well as fill out the tests and attend the video interview independently, this form of online assessment is probably not appropriate—and an in-person assessment with more support is likely a superior option. See my FAQ page for more information on this.
