A diagnostic assessment is a detailed evaluation aimed at:
- Determining whether a diagnosis (such as a developmental or neurological condition) is present,
- Clarifying the child’s unique strengths and challenges, and
- Identifying what supports, interventions or services are needed.
A screening asks, “Is there enough concern to look deeper?”.
A diagnostic assessment asks: “Is there a diagnosis, how significant is it, and what supports are needed?”
If there are ongoing concerns with speech and language, social skills, behaviour, learning new skills, or motor skills, a diagnostic assessment helps:
- Confirm or rule out a diagnosis (like autism)
- Clarify the child’s developmental, cognitive, communicative, and social skills,
- Identify their level of support or need, and,
- Guide therapy and service planning, educational programming, referrals, and eligibility for supports and funding.
Book a diagnostic assessment to help you understand your child’s development and how to help them.
