How We Assess Your Child
Assessments help our clinical team understand what your child does well and where they need more support. We usually assess at the start of therapy, after a few sessions of building a relationship with your child and observing how they play, communicate and learn.
We always let parents know when the assessment will happen. The number of sessions depends on what we learn from the intake interview, our observations and how your child is doing on the day.
Reassessment Is an Ongoing Process
Assessment doesn’t stop after the first plan. We reassess your child regularly, usually every six months, and some assessments once a year. This shows progress and helps us update goals as your child grows.

Our clinical team chooses the right tool for your child’s age, abilities and needs.

ABLLS-R Assessment

ABA Assessment FAQs
What can I expect during an assessment?
Our clinical team looks at your child’s strengths, challenges and needs. This includes talking with you, observing your child and using standard tools such as VB-MAPP and ABLLS-R. We then share what we found and recommend next steps.
How long does an assessment take?
It depends on your child. The number of sessions depends on the intake interview, our observations and how your child is doing.
How often will my child be reassessed?
Usually every six months. Some assessments are done once a year.
Does an ABA assessment give my child a diagnosis?
No. ABA assessments look at skills and learning needs. They are not a diagnosis. Your doctor or a psychologist can help with a diagnosis of autism spectrum disorder (ASD).
Is the assessment covered by funding?
ABA Compass is an Ontario Autism Program (OAP) listed provider, and we also accept private funding. Many insurance plans cover ABA therapy, but coverage depends on your provider and plan, so please check with them.
