ADHD and Autism Diagnostic Assessments
In an effort to increase access in the neurodivergent community Prism Therapy Collective provides Diagnostic Assessments. Prism supports self-identification and recognizes that there is often still a desire to have a mental health clinician confirm what you already suspect about yourself and your experience.
The assessment process will vary based on an individual's needs and desired use of the diagnosis. Whether this is for self understanding, therapeutic use or access to accommodation or medication support, we are happy to work with you to determine the best fit.
Diagnostic evaluations are currently available to Massachusetts residents ages 13 and up, virtually or in person in Acton, MA, and most clients are seen within two to three weeks of reaching out, faster than many waitlists for this kind of assessment.
Please note that different institutions (school, healthcare, work) may have varying requirements for diagnosis. We recommend that you look at what is required if you are seeking accommodations with a specific program. We are happy to help sort this out with you. This diagnostic process is not a psychological evaluation.
Confidentiality is our priority and your private medical information will not be provided to any entity without your express written permission. Prism remains actively informed of the conversations impacting those with Autism, ADHD and the broader neurodivergent community.
How Can a Diagnostic Assessment Help?
-
For many people, the most meaningful outcome of an assessment is a deeper understanding of themselves. A diagnosis can provide language for lifelong experiences, reduce self-doubt, guide therapy or coaching, and help you identify strategies that align with how your brain works.
-
A formal assessment may support requests for a 504 Plan by documenting how a disability substantially limits one or more major life activities.
Approval is determined by your child's school, and additional documentation may be requested.
-
Many colleges and universities require documentation to approve disability accommodations, such as extended testing time, reduced-distraction testing environments, note-taking support, or housing accommodations.
Requirements vary by institution, and while our formal diagnostic assessment meets the documentation standards many schools request, each college makes its own determination regarding eligibility and approval.
-
A formal diagnostic assessment can support requests for reasonable workplace accommodations under the Americans with Disabilities Act (ADA).
Examples may include flexible scheduling, written instructions, noise-reducing supports, remote work, or other accommodations based on your individual needs. Approval is determined by your employer and depends on your job duties and workplace policies.
-
Some medical providers require a formal diagnostic evaluation before prescribing medication for conditions such as ADHD.
Because prescribing practices vary, we recommend checking with your current healthcare provider. If needed, we're happy to provide referrals to neurodiversity-affirming prescribers.
Why choose to work with M?
M is an independently licensed clinical social worker with over a decade of experience supporting neurodivergent individuals. They have extensive training in ADHD and autism assessment, diagnostic evaluation, and neurodiversity-affirming best practices.
They recognize that many people, particularly women, LGBTQIA+ individuals, and those who have learned to mask their traits, have gone undiagnosed or misdiagnosed for years due to outdated, deficit-based understandings of ADHD and autism.
Using evidence-based assessment tools, a trauma-informed diagnostic interview, and a collaborative, affirming approach, M works to understand the whole person, not just a checklist of symptoms. Their goal is to provide clarity, validation, and practical recommendations that help individuals better understand themselves and access the support they need.
M understands that seeking a diagnosis can be both validating and emotional. They strive to create an assessment experience where clients feel heard, respected, and understood—whether the assessment confirms what they've long suspected or provides a different perspective.
If you need documentation for school, work, or other accommodations, the Formal Assessment is the right fit — it’s the only option that includes a full evaluation report and an accommodation request letter. If you’re looking for personal clarity and self-understanding without formal documentation, the Informal Assessment offers a shorter, more affordable path. Check out the information below for more details.
If you're unsure which option best meets your needs, we're happy to help you decide.
