How Long Does ABA Therapy Take to Work?

ABA therapy can prove highly beneficial for children who are diagnosed with Autism. Families can expect to see improvements within the first few months, with life-changing progress obtained within a couple of years of consistent therapy. Lasting independence is often achieved after several years of regular therapy, reinforced in a classroom-like environment and at home. 

How Long Does ABA Therapy Take to Work?

Several factors influence the timeline your child will require for initial and lasting results from ABA therapy. 

Age

The most important factor is age. The sooner a child begins ABA therapy, the more substantial the results and timeline will be. If a child can start before age five, their neuroplasticity will help them achieve faster improvements. 

Intensity

The second factor is the program’s intensity. If a child is able to participate in a high-intensity program at our treatment center, anywhere between 25 and 40 hours per week, it can provide faster results. Even if a child can only participate in a low-intensity program, it can lead to lasting improvements, but the timeline is often extended. 

Consistency

How consistently ABA therapy strategies are applied will directly influence the timeline. If, for example, you can replicate the strategies your child learns at school or in therapy at home, it can expedite the timeline. 

Involvement

As a parent, you play an essential role in the timeline for treatment. Active reinforcement of the skills your child is taught, by parents and caregivers alike, is imperative. The more these skills can be reinforced at home, the faster a child can learn the necessary behaviors and make progress.  

Needs

Each child with Autism will have unique challenges and strengths. For some, simple skills can be acquired in a matter of weeks, but more complex skills like social behaviors might take months. Reducing challenging behaviors can take years. 

ABA Timeline

During your child’s ABA therapy sessions, you will see different changes. 

We have different focus areas that we teach throughout the ABA timeline:

  • 1-3 months: Foundational skills and program development
  • 3-6 months: Functional skills and behavior management plans
  • 6-12 months: Complex behaviors and skill generalization
  • 1 year +: Complex skills and preparation for educational transition

For each of these focus areas, you can expect to see different changes in your child:

  • 1-3 months: Increased eye contact, shifts in behavior, the ability to follow simple instructions
  • 3-6 months: Improvements in skill maintenance, targeted communication, and reduction in challenging behaviors
  • 6-12 months: Advancements in language skills, social skills, and increased independence
  • 1 year +: Advanced communication skills, social skills, emotional regulation, and long-term independence

As your child continues to participate in ABA therapy and receive reinforcements at home and at school, these improvements will grow. 

So, how long does ABA therapy take to work? The timeline for results for a child with Autism will vary based on learning style, needs, consistency, and parental involvement. The goals of ABA therapy are to help create social skills and the foundation for independence and improved behavior/daily routines. The more these skills are integrated into the home and school, the faster the timeline will be. When you reach out to our team, we can help you gauge the timeline for your child based on their needs and other factors.

FAQ

What Influences the Timeline for ABA Therapy?

There are many things that can influence the timeline for ABA therapy, and how long your child might need it. The most important thing is the age at which your child starts. The earlier a child begins ABA therapy, the more substantial the results can be. Consistency is also important; when a child accesses the same strategies at school and at home, it can help reinforce key concepts. 

When Will I See Changes in My Child with ABA Therapy?

Progress in ABA therapy is not linear; it occurs in phases. For example, after your child has participated in ABA therapy for a few months, you might see changes in foundational skills such as following simple instructions, increased eye contact, and improved rapport. After one year, the focus on complex behaviors might lead to changes in language and social skills, as well as increased independence. After several years, you might notice changes in emotional regulation and community skills, too. 

How is Progress Monitored with ABA Therapy?

Our institution relies on formal assessments, given every few months. With help from certified behavior specialists, we can work with you to determine how well a treatment plan is working and, from there, what changes might need to be made to create better self-care routines or social skills.

Does the Setting for ABA Therapy Influence the Timeline?

Yes, in general, the skills a child develops are best when they are developed in a school-like community, surrounded by qualified professionals who lay the foundation, a foundation that parents can build on at home. However, some of the most important factors to influence the timeline for your child are the intensity of the therapy (how many hours per week), the family/caregiver involvement, and consistency. 

What Are the Advantages of Clinic-Based ABA Settings?

At our Chicago-based clinic, children with Autism can acquire foundational skills faster in a structured environment with fewer distractions. They also have the opportunity to enhance socialization and build peer skills in supervised settings. At home, these key skills can be enhanced and the ABA timeline advanced through natural integration into daily routines like mealtimes and bedtimes.
