If you've researched ABA, you've probably hit a wall of acronyms. Three you'll hear most are DTT, NET, and NDBI. Here's what each means in plain terms — and how a good program blends them around your individual child.
DTT — Discrete Trial Training. Structured, one-skill-at-a-time teaching. A skill is broken into small steps and practiced in clear, repeated "trials," usually at a table, with reinforcement for success. DTT shines for building specific foundational skills that benefit from focused repetition. Done well — and done kindly — it's clear and effective. Done rigidly, it can feel drill-like, which is why it should always be paired with the next two.
NET — Natural Environment Teaching. Teaching that happens during play and everyday routines, using your child's own interests and motivation. If your child loves trains, we teach language, turn-taking, and problem-solving through the trains. The big advantage: skills learned in real-life contexts are far more likely to transfer to real life — the playground, the kitchen, the classroom.
NDBI — Naturalistic Developmental Behavioral Intervention. A family of approaches (you may hear names like ESDM or PRT) that blend behavioral science with child-development principles. NDBIs are play-based, follow the child's lead, and focus on social communication and connection within natural interactions. They reflect where the field has moved: warm, relationship-centered, and developmentally grounded.
How we actually use them. No single method is "the answer." The best programs are individualized — pulling structure from DTT when a skill needs it, the natural motivation of NET, and the relationship-first spirit of NDBIs, all matched to your specific child and adjusted as they grow. What stays constant across all of it: your child's assent, their interests, and their dignity lead the way.
If you'd like to understand which approaches your child's BCBA is using and why, just ask — we're always happy to walk you through the plan.
