ABA therapy is not one teaching style — it uses three main methods. Discrete Trial Training (DTT) is structured, at-the-table teaching with short, repeated tries and immediate rewards. Natural Environment Teaching (NET) weaves learning into play, snacks, and daily routines so skills happen in the real world. Verbal Behavior (VB) is a method for teaching language by purpose — asking, naming, repeating, conversing. A strong ABA therapy program for children blends all three to match how your child learns best.
Parents sometimes call our intake line with a confused, exhausted question: “My friend’s son does ABA therapy, but they sit at a table and run drills. My neighbor’s daughter does ABA and the therapist just plays on the floor. Which one is the real ABA therapy?”
The honest answer is: both. And a third one neither has described.
Applied Behavior Analysis is a science, not a single procedure. Inside that science live many teaching methods — three of which form the core of how children receive ABA therapy services today. A skilled BCBA does not pick one and stick to it like a brand loyalty. They diagnose the child, identify the skill being taught, and choose the method that fits the child and the skill in front of them.
Discrete Trial Training was the earliest large-scale ABA therapy method, developed in the 1960s and famously expanded by Ivar Lovaas at UCLA. The mechanics are deliberately simple:
Trials are short, repeated, and massed — meaning the same target is presented many times in close succession.
DTT is the right choice when: - A child needs many, many repetitions to acquire a foundational skill (early matching, imitation, receptive ID) - We are teaching a brand-new skill from zero - We need to control variables tightly to see what is and isn’t working - The skill is best taught in a structured, distraction-reduced setting
Common parent worry: “It looks like drills. Is my child a robot?” A modern, well-run DTT program does not look robotic. Trials are paced to the child, intermixed with preferred-item breaks, and embedded with humor. DTT is a tool — not a personality.
Natural Environment Teaching, sometimes called Incidental Teaching, was popularized by Hart and Risley and refined by countless researchers since. NET takes the same behavioral principles as DTT — antecedent, response, consequence — and embeds them in the child’s natural routines and play.
A NET session might look like this:
Notice the difference. The motivation came from the child, not from the therapist’s choice of target. The reinforcer was the actual thing the child wanted, not a token. Generalization happens automatically because the teaching is happening in the place the skill will be used.
NET is the right choice when: - A child has acquired a skill in DTT and needs to use it in real life (generalization) - We are teaching language, social, or play skills that require natural motivation - The child is highly motivated by real-world reinforcers - We need skills to hold up across people, places, and items
Common parent worry: “It looks like they’re just playing.” They are playing. They are also teaching, taking data, and shaping behavior in ways most parents cannot see without training. NET demands more clinical skill than DTT, not less.
Verbal Behavior is an analysis of language — not a setting, but a framework. It comes from B.F. Skinner’s 1957 book Verbal Behavior and was operationalized for ABA therapy by Mark Sundberg, James Partington, Vincent Carbone, and others.
The key insight: language is not one big skill. It is many separate skills that look the same on the surface but are functionally different. A VB-informed ABA therapy program teaches each one explicitly:
A child can be fluent in tacts (naming everything they see) and have almost no mands (cannot request what they want). They look “verbal” — but they cannot get their needs met. A VB-informed BCBA spots this and prioritizes manding first, because manding gives the child power.
VB is the right framework when: - A child has language delays, scripted speech, or limited functional language - We see splinter skills — strong in one verbal operant, weak in another - The child is preverbal and we need a roadmap for building language - Parents want their child to actually communicate, not just talk
In our practice, a typical comprehensive ABA therapy program for a young child looks like this across a week:
The methods are not in competition. They are layered.
Last year we welcomed a four-year-old we’ll call A. into in-home ABA therapy. A. had been in another program for eight months that was nearly all DTT. He could match shapes, identify colors, and complete 100-trial blocks at the table. He could not ask for water.
Our assessment showed strong tacts and echoics, almost no mands, and zero spontaneous communication at the dinner table. We restructured the program: VB-aligned mand training first (water, snack, up, open, help — five high-value mands), NET sessions tied to snack and play, and DTT preserved only for the small set of skills that genuinely needed massed trials.
Six weeks in, A. requested water from his grandmother during a family dinner. She cried. His DTT data had been stagnant for months. Once we matched the method to the missing skill, he moved.
If you are not sure which methods your child’s ABA therapy program is using — or whether the mix is right — these are reasonable questions to ask:
A confident BCBA will not be defensive about these questions. They will be glad you asked them.
DTT (Discrete Trial Training) is structured, at-the-table teaching with massed trials and immediate reinforcement, useful for acquiring new skills from zero. NET (Natural Environment Teaching) embeds teaching in the child’s natural routines and play, with the child’s own interests driving the targets. Most strong ABA therapy programs use both, in sequence.
No. Verbal Behavior is a framework within ABA therapy for analyzing and teaching language. Some programs are described as “VB-based” because they prioritize the verbal operants (mand, tact, echoic, intraverbal), but they are still ABA therapy programs.
There is no universal “best” method. Most children benefit from a blend, with the proportion shifting as they progress. Early learners often need more DTT for foundational skills; older or more verbal learners often shift toward NET and VB.
This is determined by your BCBA based on assessment and skill targets — not by a one-size formula. Many comprehensive ABA therapy programs use a fraction of total hours for DTT, with the remainder split between NET and parent training.
Worth a conversation with the BCBA. An exclusively DTT program risks poor generalization. An exclusively NET program may miss skills that require massed-trial repetition to acquire. The right answer is usually and, not or.
