What Is ABA Therapy? A Parent’s Guide for Bangladesh
Reviewed by the clinical team at Tender Twig (IBA-supervised) · Updated June 2026
ABA therapy (Applied Behavior Analysis) is a scientifically validated treatment that uses positive reinforcement to teach communication, social, learning, and daily-living skills while reducing behaviours that interfere with learning. It is the most widely researched intervention for autism and developmental delays, and it is delivered by trained therapists who set individual goals and track each child’s progress with data.
How does ABA therapy work?
ABA is built on a simple idea: behaviour that is followed by something rewarding is more likely to happen again. Therapists break larger skills — like asking for help, taking turns, or getting dressed — into small, teachable steps, then reinforce each step as the child masters it. They observe the “ABCs” of behaviour (the Antecedent that comes before, the Behaviour itself, and the Consequence that follows) to understand why a behaviour happens and how to support a more helpful one.
Crucially, ABA is data-driven. Progress is measured at every session, and the plan is adjusted based on what the data shows — not guesswork. Modern, ethical ABA is also child-led and play-based: it respects each child’s pace and personality rather than trying to “manage” them.
Who can ABA therapy help?
ABA is best known for supporting children with autism, but its principles also help children with ADHD, speech and developmental delays, and behavioural challenges. It can build functional communication, attention and learning readiness, social and play skills, emotional regulation, and independence in everyday routines.
When should ABA therapy start?
ABA can begin as soon as a developmental concern is noticed — often between ages 2 and 6, when the brain is most adaptable. Earlier intervention generally leads to stronger long-term outcomes, which is why early intervention programmes focus on this window. That said, ABA can still benefit older children and adolescents. If you’re unsure, a quick developmental screening is a gentle first step.
How many hours of ABA does a child need?
There is no single answer — it depends on the child’s needs and goals. Focused programmes may involve a few hours per week, while comprehensive early-intervention plans are more intensive. The right number of hours should always be set after an individual assessment and reviewed regularly as the child progresses.
ABA vs. speech and occupational therapy
These therapies overlap but focus on different things. ABA targets behaviour, learning, and life skills through reinforcement; speech therapy targets communication and language; occupational therapy builds motor, sensory, and self-care skills. Many children benefit from a combination, and a good assessment helps identify the right mix for your child.

Frequently asked questions
Is ABA therapy evidence-based?
Yes. ABA is endorsed as an evidence-based practice for autism by major bodies including the US Surgeon General and the American Psychological Association, supported by decades of peer-reviewed research showing gains in communication, social, and adaptive skills.
Is ABA therapy only for autism?
No. While ABA is best known for autism, its principles also help children with ADHD, developmental delays, and behavioural challenges build communication, attention, and daily-living skills.
How long does ABA therapy take to show results?
It varies by child, goals, and intensity. Many families notice early progress within the first few months, while broader developmental gains build over a longer, consistent course of therapy with regular review.

Yes. Tender Twig provides internationally certified (IBT) ABA therapy, supervised by an International Behavior Analyst (IBA), in Gulshan 1, Dhaka, with programmes from early intervention through school readiness and classroom support.
