Can ABA Therapy Raise IQ? The Real Benefits for Children

Many families hope ABA will “fix” IQ. But IQ is just one measure of ability, and ABA’s true power lies in teaching skills that make everyday life easier and more joyful.

A family I worked with once feared their daughter’s low test scores defined her future. With school-based ABA, she learned to communicate her needs and play with peers. That progress was far more valuable than a score.

Let’s explore what research says and, more importantly, what this means for your child.

Understanding IQ and Its Limits

Before diving into ABA’s role, it’s important to understand what IQ really measures. IQ tests are designed to evaluate certain kinds of problem-solving, reasoning, and memory skills.

But they don’t capture the full range of intelligence or potential.

What IQ Tests Measure

• Verbal reasoning
• Working memory
• Problem-solving skills
• Processing speed

What IQ Tests Don’t Measure

• Creativity
• Emotional intelligence
• Social skills
• Adaptability in daily life

For children with autism, test scores can sometimes underestimate abilities because communication or attention challenges may interfere with performance. That’s why IQ should always be viewed as one piece of the puzzle—not the whole picture.

What Does ABA Therapy Do?

ABA is not about raising numbers on a test—it’s about helping children thrive in daily life. The therapy uses evidence-based strategies to teach communication, learning readiness, social, and independence skills.

Core Skills Taught in ABA

• Language and communication: Learning to express needs, wants, and ideas.
• Learning readiness: Improving attention, focus, and the ability to follow instructions.
• Daily living skills: Building independence with routines like dressing, eating, and hygiene.
• Social skills: Strengthening connections with peers and family members.

Why This Matters

These skills don’t just improve everyday life—they also create conditions that may help children perform better on structured assessments, including IQ tests.

Can ABA Improve IQ Scores?

Research suggests that children who participate in intensive, early ABA programs often make gains in learning and language development. In some studies, this has been linked to increases in IQ scores.

Why IQ Scores May Improve

• Better communication: Children can understand test questions and express answers more effectively.
• Improved focus: ABA helps kids develop attention skills needed for test-taking.
• Stronger problem-solving: By practicing reasoning in everyday contexts, children may apply these skills in assessments.

Important Note for Parents

ABA does not “teach to the test.” Instead, it supports underlying skills that give children the opportunity to demonstrate their true abilities—sometimes reflected in higher IQ results.

Why IQ Isn’t the Full Story

While it’s encouraging to see improvements in IQ scores, parents should remember that IQ is not the ultimate measure of success.

Many children with autism thrive with ABA therapy regardless of their test results.

Beyond the Numbers

• Daily life skills: Independence in dressing, eating, or managing routines
• Social growth: Building friendships and enjoying peer activities
• Confidence: Feeling capable and supported in learning environments

The Real Goal of ABA

The true purpose of ABA therapy isn’t about raising IQ—it’s about giving children tools to succeed in school, at home, and in the community.
