Early Skills Predict Long-Term Gains

This cluster shows how talking, pointing, and learning scores at age 2 shape life skills at age 19. Kids who start with stronger language and play need fewer supports later, while lots of early ABA hours boost talking and daily living skills for everyone. It tells BCBAs to measure toddlers’ words, IQ, and joint attention, then plan many early hours and lifelong help for those on the lowest paths.

Key Findings

What 97 articles tell us

  1. Early joint attention behaviors — like pointing, showing, and following another person's gaze — are among the strongest predictors of better outcomes in adolescence.
  2. Autism symptom severity is dynamic, especially in the first few years, and girls are more likely to improve than boys.
  3. For autistic children with lower cognitive ability, personal daily living skills predict the best adult outcomes.
  4. Almost a third of children who lose their toddler ASD diagnosis still need services in early elementary school for other conditions.
  5. Adaptive functioning follows distinct trajectories in autism, with key turning points around ages five to six and nine to ten — making these critical windows for intervention review.

Frequently Asked Questions

Common questions from BCBAs and RBTs

Joint attention behaviors like pointing and responding to another's gaze, early language, cognitive ability, and self-care skills are the strongest early predictors. Children who develop these skills earlier tend to do better in school, work, and daily life.

Yes. Research shows that severity is dynamic for many children, especially in social communication. Improvement is more common in girls and in children who receive consistent early support. But it is not guaranteed and should not be assumed.

Many still need services. Studies show that nearly a third of children who no longer meet ASD criteria in early elementary school have ADHD, speech disorders, or intellectual disability that requires ongoing support.

At minimum, reassess at major transitions — entering kindergarten, starting third grade, beginning middle school, and preparing for adulthood. Research shows key turning points at ages five to six and nine to ten where trajectories often shift.

For clients with lower cognitive ability, personal self-care skills matter most. For those with higher cognitive ability, community-based skills like using public spaces, managing money, and pre-job tasks are the strongest predictors of adult independence.
