You’ve made the decision to pursue ABA therapy for your child. Maybe you’re newly diagnosed and want to start early intervention. Maybe you’ve been searching for more effective support and a professional recommended ABA. Whatever brought you here, your next step is typically a comprehensive assessment by a Board Certified Behavior Analyst (BCBA). If you’ve never been through this process before, it’s natural to feel uncertain about what happens during an ABA assessment. Let’s walk through what you can expect.
Before the Assessment: Preparation
Once you schedule your assessment, the ABA provider will send you preliminary paperwork. This typically includes:
- Background and medical history forms
- Developmental history (when your child met milestones, diagnosis information)
- Current behaviors and skills you’re concerned about
- Medications and medical conditions
- Information about your family and home environment
The BCBA reviews this information before meeting you to prepare relevant assessment tools and discussion topics. Come prepared with specific examples of your child’s strengths and areas of concern. The more detailed information you provide, the more focused and helpful the assessment will be.
The Assessment Day: What Happens
Duration: A comprehensive assessment typically takes 2-4 hours, depending on your child’s age, complexity of needs, and whether it’s conducted in one session or multiple appointments.
Location: Assessments can occur in the clinic, your home, or a school setting—wherever provides the most accurate picture of your child’s functioning. Many BCBAs prefer in-home or school assessments because they capture your child’s behavior in natural environments.
The Assessment Components
1. Interview and History Review
The BCBA will conduct a detailed interview with you (and sometimes teachers or other caregivers). They’ll ask about:
- Your child’s developmental history and current functioning
- Specific behaviors that concern you and when they occur
- Your family’s strengths and priorities for treatment
- What you’ve already tried and whether it worked
- Your child’s learning style, preferences, and motivators
- Medical and sensory issues relevant to treatment planning
This conversation isn’t just fact-gathering; it’s about understanding your child holistically and learning what matters most to your family. The best assessment happens when the BCBA truly listens and collaborates with you.
2. Observation of Current Behavior
The BCBA will observe your child in structured and unstructured contexts. They’ll watch how your child interacts with you, responds to requests, engages in play, and handles transitions or demands. If your child exhibits challenging behaviors, the BCBA will try to observe these in action to understand the triggers and patterns.
3. Skills and Developmental Testing
The BCBA may administer standardized tests to assess your child’s developmental level across different domains:
- Communication: Language comprehension, speech production, pragmatic language
- Social/Emotional: Social understanding, emotional regulation, peer interaction
- Adaptive Living Skills: Self-care, community skills, daily functioning
- Academic/Pre-Academic: Readiness skills, early academic abilities
- Motor Skills: Gross and fine motor development
These assessments give concrete information about where your child stands compared to same-age peers and help identify specific skill deficits to target in treatment.
4. Functional Behavior Assessment (FBA)
If your child engages in challenging or problem behaviors, the BCBA will conduct or review an FBA. This special assessment focuses on understanding the function of the behavior—why it’s happening. They’ll analyze:
- What typically happens before the behavior (antecedents)
- The exact nature of the behavior
- What consequences follow and what your child seems to get out of it
- Patterns: when, where, and with whom the behavior occurs most frequently
Understanding behavioral function is crucial because it tells us how to teach replacement skills and modify the environment to reduce motivation for problem behavior.
After the Assessment: Results and Treatment Planning
Within 1-2 weeks, the BCBA typically prepares a comprehensive written assessment report that includes:
- Summary of your child’s strengths and current functioning
- Areas of concern and specific skill deficits
- Clear, measurable goals for treatment
- Recommended treatment approach and frequency
- Specific interventions tailored to your child’s needs
- Your role as a parent in supporting progress
- Expected timeline and potential outcomes
You’ll have a meeting (or call) with the BCBA to review the assessment results, ask questions, and develop your child’s individualized treatment plan. This is collaborative—your input shapes the priorities and approach.
What Makes a Good Assessment?
The best assessments are thorough, collaborative, and grounded in understanding your child as a whole person, not just a collection of deficits. The BCBA should:
- Take time to truly understand your child and family
- Ask clarifying questions when you describe concerns
- Observe your child directly, not just rely on parent reports
- Explain their findings in understandable language
- Collaborate with you on what matters most for treatment
- Give you a clear understanding of what ABA would entail and what progress looks like
Providers like Magical Moments ABA are known for conducting thorough, family-centered assessments that truly capture each child’s unique needs.
Questions to Ask During Assessment
Don’t hesitate to ask:
- What are my child’s primary skill areas to target?
- How many hours per week of ABA does my child need?
- What does treatment typically look like week-to-week?
- How often will my child be reassessed?
- How will you measure progress and communicate it to me?
- What’s my role in reinforcing skills at home?
- What’s the expected cost and how do we handle insurance?
- When can we start treatment if we decide to move forward?
Moving Forward
An ABA assessment is the beginning of your child’s treatment journey. It provides a clear picture of where your child is now and where you want to go. Many families find it enormously relieving to have concrete information about their child’s needs and a clear plan for intervention.
