Discrete Trial Training (DTT) in ABA Therapy

Discrete trial training teaches a skill by breaking it into small steps and practicing one step at a time. Each short practice is a trial: a clear cue, your child's response, and a quick reward.

At Budding Futures, our Colorado BCBAs run DTT the modern way. It stays short, playful, and built around your child, not the stiff drilling many parents remember from older ABA.

What discrete trial training looks like in a Budding Futures session

One skill at a time. A target like imitation or labeling is split into small steps your child can win.
Cue, response, reward. Each trial uses the antecedent-behavior-consequence pattern, with positive reinforcement your child cares about.
Errorless teaching. We prompt the right answer first, then fade the help, so practice feels like success, not failure.
Short blocks, then play. Trials run for a few minutes and get woven with natural play, not stacked into long drilling.
Data on every trial. Your Registered Behavior Technician records each response, and your BCBA reviews the trend weekly.
Built from a real assessment. Targets come from VB-MAPP and ABLLS-R baselines, never a one-size template.

When our BCBAs use DTT, and when they don't

Best for brand-new skills. DTT shines when a child is first learning a discrete target that needs clear, repeated practice.
Always paired with natural teaching. A skill practiced in a trial gets moved into play and routines so it sticks in real life.
Child-led and assent-based. We follow your child's engagement and stop a block when they have had enough.
Never punishment. Modern DTT rewards effort and correct responses. There is no forced compliance.
Supervised by a named BCBA. Rachel Blackburn, BCBA, our Clinical Director, oversees plans, with supervision around 20% of direct hours.
We skip it when it doesn't fit. Some goals call for natural environment teaching or functional communication training instead.

How one discrete trial works

A trial has three parts, and it is over in seconds. First comes the cue, called the antecedent. Your therapist might hold up a cup and say, "What is it?"

Then comes your child's response, the behavior. If your child says or signs "cup," that is the response we want. If they need help, the therapist gives a prompt, like quietly mouthing the word, then fades that prompt on later trials.

Last comes the consequence, a quick reward your child enjoys. That might be a tickle, a favorite toy, or praise. The reward makes the skill more likely next time. After a short pause, the next trial begins.

Repeat a target a few times and a child starts to learn it. The skill is then practiced in different rooms and with different people so it does not stay stuck to the table. That last step, generalization, is where a lot of older ABA fell short and where our plans put real focus.

DTT vs natural environment teaching

Most good plans use both. Discrete trial training builds the skill. Natural environment teaching helps your child actually use it. Here is how they compare.

Is DTT just robotic drilling?

This is the worry we hear most, and it is fair. Early ABA from decades ago leaned on long tables of repetition and sometimes punishment. Videos from that era look cold, and no parent wants that for their child.

Good DTT today is different. The trials are short, the rewards are things your child actually likes, and we stop when your child is done. We watch for engagement, not just correct answers.

At Budding Futures you can sit in on any session. If a block does not sit right, you can pause it and talk with your BCBA. We also explain this honestly on our pros and cons of ABA and is ABA harmful pages.

How Budding Futures uses DTT at home in Colorado

We bring DTT into your home, not a clinic. A Registered Behavior Technician runs the trials during a regular session, and Rachel Blackburn, BCBA, our Clinical Director, builds and reviews the plan. Every RBT finishes 40 hours of training and a competency check before working with your child.

Because we are in your living room, the skills connect to your child's real world fast. A word practiced in a trial gets used at the snack table that same hour. Parent coaching is built in, so you can run a few trials yourself between visits.

Discrete trial training is well studied. In a 2020 review, the National Clearinghouse on Autism Evidence and Practice examined decades of research and named 28 evidence-based practices for autistic children. Discrete trial training is one of them, alongside naturalistic intervention and functional communication training.

Common questions

Questions parents ask about DTT

What is a discrete trial in ABA?
A discrete trial has three parts. The therapist gives a clear cue, your child responds, and your child gets a quick reward for the right response. If your child needs help, the therapist prompts the answer, then fades that help over time. Each trial is short, and the next one starts after a brief pause.
Is discrete trial training the same as ABA therapy?
No. DTT is one teaching method inside ABA, not all of it. We use DTT for some skills, but also use natural environment teaching and functional communication training. A BCBA picks the method that fits each goal.
Is DTT harmful or robotic?
Modern DTT should not look like the rigid drilling from older ABA. Today it rewards skills instead of forcing compliance, follows the child's engagement, and stops when the child is done. At Budding Futures parents can watch any session and pause anything that does not feel right. More on this honest question →
How is DTT different from natural environment teaching?
DTT is structured and teaches a new skill in short, clear practice blocks. Natural environment teaching is child-led and happens during play and daily routines. We blend the two so a skill learned in practice gets used in real life.
What skills does DTT teach best?
DTT works well for brand-new foundation skills that need clear repetition, like imitation, matching, labeling objects, following simple directions, and early requesting. Once a skill is steady, we move it into natural play so it generalizes.
Does Budding Futures use DTT in the home?
Yes. We deliver in-home ABA across Colorado, and DTT happens in short blocks broken up with play. An RBT runs the trials, a BCBA supervises and reviews the data, and parents learn the same steps to use between sessions.
