What Is ABA Therapy?

Applied Behavior Analysis (ABA) is a scientifically validated approach to understanding and changing behavior.

ABA is highly individualized, meaning every child's program is tailored to their unique strengths and needs. It is often covered by insurance and Medicaid, making it accessible for many families.

The First Session: Setting the Stage

Where Does the First Session Happen?

The first session may take place in your home, at a clinic, in a school, or in a community setting. The location depends on the provider and what works best for your child. Many families start with an in-home session because it's a familiar environment, which can help your child feel comfortable.

Who Will Be Present?

Typically, a Board Certified Behavior Analyst (BCBA) will lead the first session. Sometimes a registered behavior technician (RBT) may also be present. You are encouraged to stay and participate. Your presence helps the BCBA understand your child's routines, communication style, and preferences. Siblings may also be present if it's helpful, but the BCBA will guide you on what's best.

What to Bring

Bring any relevant documents, such as previous evaluations, IEPs, or medical records. Also bring your child's favorite toys, snacks, or comfort items. These can be used during the session to build rapport and conduct preference assessments. Dress your child in comfortable clothing, and be ready to share your observations and goals.

The Initial Assessment: A Closer Look

The heart of the first session is the initial assessment, often called a functional behavior assessment (FBA) or skills assessment. The BCBA will gather information to create a baseline and develop a personalized treatment plan.

Observation and Interaction

The BCBA will observe your child in natural activities, such as playing, eating, or transitioning between tasks. They may interact with your child to see how they respond to different prompts, requests, or reinforcements. This observation helps identify strengths, areas for growth, and potential triggers for challenging behavior.

Parent Interview

You are the expert on your child. The BCBA will ask about your child's history, daily routines, communication abilities, social skills, and any behaviors that concern you. They'll also ask about your goals for therapy. Be honest and detailed; this information is crucial for creating an effective plan.

Preference Assessment

The BCBA will identify what motivates your child. This might involve offering different toys, activities, or snacks and seeing which ones your child chooses. Understanding preferences helps the BCBA design a reinforcement system that encourages learning.

Goal Setting and Treatment Planning

By the end of the first session, the BCBA will begin outlining potential goals. These goals are specific, measurable, and meaningful for your child's development.

Short-Term and Long-Term Goals

Short-term goals might include following a simple instruction, making eye contact, or requesting a preferred item. Long-term goals could focus on communication, social skills, independent living skills, or reducing specific challenging behaviors. The BCBA will explain how each goal will be taught and measured.

How Goals Are Measured

Data collection is a core part of ABA. The BCBA will explain the types of data they collect, such as frequency, duration, or percentage of correct responses. This data is used to track progress and adjust the plan as needed. You'll see how even small steps are celebrated.

Data Collection and Progress Monitoring

Data collection begins during the first session. The BCBA may use a clipboard, tablet, or app to record observations. This is not intrusive; it's a systematic way to ensure therapy is effective. Over time, you'll receive regular updates on your child's progress, often through graphs or written reports.

Parent Involvement and Training

Your role is essential. The BCBA will explain how you can reinforce skills at home and in the community. Many providers offer parent training sessions to teach strategies for managing behaviors and promoting learning. The first session is a great time to ask about the frequency and format of parent training.

Insurance and Costs

ABA therapy is commonly covered by private insurance and Medicaid. During the first session, the BCBA or a billing specialist will discuss your coverage, copays, and any authorizations needed. Start with ABA is a free service that can help you find a BCBA-led provider who accepts your insurance, including Medicaid. We do not charge families; we simply match you with vetted providers in your area.

What Happens After the First Session?

After the assessment, the BCBA will write a comprehensive treatment plan. This plan is shared with you and, if needed, with your insurance company. Regular therapy sessions will begin, typically several times per week. The BCBA will continue to supervise the program, and you'll have ongoing communication about progress and adjustments.
