The Importance of Early Intervention

Services for Children with Autism

In the last ten years, great strides in research and understanding of Autism Spectrum Disorder (ASD) have improved accessibility to diagnosis and early intervention services, including ABA therapy, for children with Autism Spectrum Disorder (ASD).


Before this, many children with ASD were not given an accurate diagnosis or appropriate supports.


Very little, if any, early intervention therapy was readily available for families in need.

Today we know that the earlier we intervene the better. Early intervention can make a distinct difference in the outcomes for children who are on the autism spectrum.

Research spanning 30 years has shown the benefits of early intervention (Conroy, Dunlap, Clarke, & Alter, 2005). Early detection and intervention can provide a child appropriate replacement behaviors.

This article aims to emphasize the importance of early intervention services for individuals with ASD and how parents, caregivers, and therapists can effectively help.

This article will also describe potential indicators of ASD, when early intervention should begin, how to determine the appropriate concentration of weekly therapy hours, what is accomplished during early intervention ABA treatment, and how to find the right early intervention treatment program for your child.

What are the Signs of Autism?

A great reference for ASD information, including early warning signs, is the CDC website: While every case of autism presents in a unique way, some commonly seen signs include but are not limited to:

  • Limited eye contact
  • Limited social interactions with others (such as sharing items or pointing)
  • Limited responding to their own name
  • Limited social engagement with peers (do not approach peers with interest)
  • Limited language understanding (receptive or expressive language)
  • Delayed or absent vocal speech
  • Limited appropriate play skills (not playing with toys how they were intended)
  • Extreme emotional responding to changes or transition of activities
  • Engaging in repetitive vocal sounds or physical actions
  • Sudden regression or loss of previous skills (language or play skills)
  • The occurrence of problem behaviors (aggression, self-injury, property destruction)
Signs Of Autism

These symptoms can be seen and detected as early as 12 to 18 months of age and in some cases even earlier. Children should be monitored throughout development for warning signs.

High-risk groups such as children who have other siblings diagnosed with Autism should be monitored closely by physicians, parents, and caregivers.

How Early Should Intervention Begin?

Parents and caregivers are often very surprised to hear that treatment for Autism can begin at any age.

However, diagnosis by a developmental pediatrician or psychologist is often required and has been as early as 18 months old.

Not only should intervention begin as soon as possible, but new research on early intervention ABA has also determined that an average of 30+ hours per week is ideal.

How Concentrated Should Early Intervention Treatment Be?

Research on the effectiveness of ABA therapy indicates that a high amount of hours (30+ hours per week) at an early age (before age 5) is the most beneficial for clients.

However, there is much to consider when evaluating ABA programs. ABA treatment plans are categorized in two different ways, comprehensive and focused.

Comprehensive treatment plans address global delays across many different developmental domains and generally consist of 30+ hours per week of therapy.

Focused treatment plans address a few specific behavioral targets such as problem behavior reduction and are generally lower hours per week.

Please refer to the for more ABA guidelines.

The amount of hours needed per week to make meaningful progress is determined by the comprehensive assessment conducted at the intake with each client.

The recommended hours that each client receives is dictated by the assessment outcomes and by the supervising Board Certified Behavior Analyst or BCBA.

Each case will be supervised by a BCBA who will conduct the initial and ongoing assessments, program goals for each client, monitor progress on goals, overlap and supervise direct service technicians, implement a behavior reduction plan if needed, and consult with the family.

For more information about BCBAs and supervision requirements for ABA treatment, please visit

The recommended ABA therapy hours are prescribed by the supervising BCBA much like a medical doctor prescribes medication to treat an illness.

Coverage of ABA services through private or state insurance requires pre-authorization and it is essential that the entire treatment plan is implemented correctly and followed by all caregivers.

What is Accomplished in Early Intervention Treatment?

During ABA therapy, the treatment is individualized and targets a range of difficulties that children with ASD experience to help them participate meaningfully at home, school, and social settings.

Work is done on communication skills, daily living skills, imitation skills, play and social skills, cognitive skills, gross and fine motor skills, behavioral and safety skills.

When it comes to certain maladaptive behavior a child may have, the function of that behavior is identified and addressed.

This individualized treatment provides the most effective results.

Early Intervention Treatment

How Do I Find the Right Early
Intervention Treatment Program for My Child?

Every child with an ASD diagnosis will have access to specific state funded programs to address deficit skills. However, private health insurance also covers a multitude of services including ABA, speech, occupational therapy, and feeding therapy. Most ABA agencies will help you navigate what your particular plan covers and what is your patient responsibility.

When you look for an early intervention therapy or school program, look for the following elements:

Applied Behavior Analysis

ABA is an essential part of any program or school placement. Evaluating whether or not a program implements ABA correctly and consistently is key. All therapy models should be ABA-based and the staff should all have sufficient ABA training.


You will want to choose an early intervention program or developmental preschool that follows an evidence-based academic curriculum, is founded on assessments of the children in the program, and the data is made available to families.


A great program will have highly trained staff. Generally, you will want to have staff that are Registered Behavior Technicians (RBTs) working with your child. You will also want to evaluate the turnover rate that any agency has to ensure your child works with consistent and familiar staff without any disruptions. You will also want to ensure your child’s case is overseen by a BCBA and that you or your family has access to this BCBA through parent training.


You will want to ensure the ABA agency takes accurate and regular data throughout the entirety of your child’s services. Make sure you have a way to access that data on a regular/daily basis to ensure you are familiar with what your child is working on and how they did each day. Many agencies utilize an online patient portal that gives parents access to see their child’s program book and any billing corresponding to their child’s therapy.


When you are looking for the right early intervention program, ensure that the agency will coordinate care with your other service providers and with you and your family on a regular basis.

Behavior Intervention and Support

Make sure that your early intervention program is able to evaluate and addresses any problem behaviors your child might exhibit. This will include a functional analysis, development of an intervention plan and specific parent training regarding the implementation of the plan.

Parent training

You will want to ensure that the early intervention program has a built-in parent training model or requirement. This will ensure consistent implementation of behavior plans as well as ensuring the maintenance of learned skills.
