Key Points:
That first meeting with a BCBA is a big step. While you know your child best, it can feel like a lot to sum up your daily life on the spot. And when you're trying to explain what your child needs, a forgotten detail can feel like a big deal.
Here's the thing: what to tell a BCBA before ABA starts doesn't have to be long or perfect. The most helpful details are usually the simple ones, such as what your child loves, when the day flows smoothly, when things get tough, and what you're already noticing at home.
This first conversation is just about painting a fuller picture of your child's daily life. It's not a test or a diagnostic evaluation. A little prep can help the meeting feel calmer, clearer, and actually useful.

An ABA evaluation usually draws from more than one source. The BCBA will interview caregivers, review records, and watch your child directly. Your daily observations give context that tests and forms cannot capture. You see what time of day works best, which transitions go smoothly, and what situations usually fall apart.
Caregiver input helps early. Parent-mediated interventions focus on everyday routines, communication, engagement, daily living skills, and challenging behavior.
Routines give the BCBA a picture of when your child is most settled, when the day gets hard, and where support may be needed first. You do not need to prepare a formal report. A clear description of how the day usually goes is enough.
Think about the parts of the day that feel predictable and calm. Maybe mornings run well because your child likes the same breakfast and the same order of getting dressed. Maybe bath time works because they enjoy water. Maybe they settle down easily at bedtime when the lights dim and the same song plays.
Share what works. Those child routines in ABA show strengths, not just problems. The BCBA can build on what already feels comfortable for your child.
Difficult moments often happen around the same situations. Talk about what tends to fall apart.
These details help the BCBA understand where your child may need extra support.
The conversation should go beyond problem behavior. The BCBA also needs to know how your child asks for help, shows interest, and spends time when they are happy.
Describe how your child lets you know what they want or need:
This ABA assessment information helps the BCBA understand where functional communication may need support first.
Talk about what your child loves:
Those interests are not just fun facts. They become tools the BCBA can use to build skills and create moments of success.
When caregivers describe patterns in plain language, the BCBA can start connecting what happens before the behavior, what the behavior looks like, and what follows it.
Think about what was going on right before things got difficult:
Those triggers do not always cause a problem, but noticing behavior patterns at home helps.
Describe what you see:
You do not need to know why the behavior happens. The BCBA will use your examples, along with observations and other assessment tools, to figure that out.
If your child shows aggression, self-injury, elopement, climbing, ingesting or mouthing inedible items, or property destruction, mention it early. Safety details help the team plan appropriately from the start.

Behavior is rarely just about the moment. Things like sleep, hunger, medication, or illness often shape a child's day in ways that are easy to overlook. Sharing these simple details helps create a much clearer picture.
Share your child's sleep schedule and whether they wake often at night. A 2024 clinical review reported that clinically significant sleep problems affect over 80% of children with autism, so sleep details are worth mentioning even if they do not seem related at first.
Talk about food refusal or very limited foods. A 2025 study review reported a 55% prevalence of gastrointestinal symptoms in children with autism, which supports asking caregivers about constipation, stomach pain, or feeding problems during intake.
Mention any recent illness, medication changes, allergies, seizure history if relevant, or toileting patterns that have changed.
Describe your child's school or daycare schedule. Talk about transportation issues if getting there is hard. Mention grandparents or extended family who help. If rules are different across homes, that is useful to know. If other therapies or providers are already involved, share that too.
At ChildBuilders, we highlight family collaboration, caregiver coaching, and coordination with other professionals so the team works together instead of in separate directions.
Helpful paperwork can save time, but missing paperwork should not stop you from starting the conversation. Bring what you have. Leave the rest.
Standard ABA assessment uses several sources, not just one form or one test. The caregiver interview for ABA is one part of a bigger picture.
If you want a simple way to get ready before starting ABA therapy, follow these steps.

Yes. More than one caregiver can share information with the BCBA, and that can help when a child's behavior looks different across people, times, or settings. ABA assessment often uses interviews, record reviews, and direct observations from multiple sources, so the clinician gets a fuller picture.
Not knowing why the behavior happens is common. A BCBA does not expect caregivers to solve the pattern before intake. The first meeting is used to gather examples, look at what happens before and after the behavior, and connect those details with observation and other assessment tools.
Yes. Sleep or stomach issues are worth mentioning even if the link is unclear. Sleep problems are common in children with autism, and gastrointestinal symptoms are also frequently reported, so those details may help the BCBA ask better follow-up questions and build a more realistic starting plan.
A stronger first BCBA conversation often starts with simple home details: routines, communication, triggers, strengths, and health changes that shape the day. When caregivers share that everyday picture early, the team has a better starting point.
