ABA & Autism Glossary for Parents, Pediatricians, and ABA Professionals
Understanding autism, ABA therapy, early intervention, and child development terms can feel overwhelming for families and professionals alike. The ABA Works Glossary was created to help parents, caregivers, pediatricians, Behavior Technicians, and BCBAs better understand common autism and ABA-related terminology.
Our clinical team explains each term in parent-friendly language while also providing clinically accurate information grounded in evidence-based Applied Behavior Analysis (ABA). Whether you are learning about early signs of autism, exploring clinic-based ABA services, searching for autism resources, or considering a career in ABA, this glossary is designed to support you.
