This comparison draws in part from “Conventional Versus Progressive DTT | Learning | 1 Hour” (Autism Partnership Foundation), and extends it with peer-reviewed research from our library of 27,900+ ABA research articles. The decision framework, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →One of the most consequential decisions a behavior analyst makes is not just what intervention to use, but how to approach the clinical question in the first place. For conventional versus progressive dtt | learning | 1 hour, the difference between an evidence-based, individualized approach and a traditional, protocol-driven one can significantly impact outcomes.
This guide lays out the key factors side by side to support your clinical decision-making.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Primary source of interventionist control | Conventional DTT: predetermined protocol (SD wording, prompt hierarchy, reinforcer, criteria) | Progressive DTT: in-the-moment assessment of learner behavior (attention, latency, error patterns, engagement) |
| Prompt fading approach | Conventional DTT: predetermined prompt hierarchy with fixed criteria for fading | Progressive DTT: dynamic prompt adjustment based on real-time evaluation of learner response capability |
| Reinforcement procedure | Conventional DTT: pre-specified reinforcer with fixed delivery parameters | Progressive DTT: reinforcer selection and density adjusted within session based on engagement and satiation indicators |
| Implementation fidelity assessment | Conventional DTT: straightforward fidelity checklist based on protocol adherence | Progressive DTT: fidelity requires assessing accuracy of in-the-moment decisions against established decision rules |
| Best-fit learner profile | Conventional DTT: consistent motivational state, low prompt dependence history, new skill acquisition phase | Progressive DTT: variable motivation, prompt dependence history, complex learning targets, in-session engagement problems |
| Training demands on interventionist | Conventional DTT: mechanical execution competency; lower clinical judgment requirements | Progressive DTT: requires both mechanical execution and trained clinical judgment for in-the-moment decision-making |
The ABA Clubhouse has 60+ on-demand CEUs including ethics, supervision, and clinical topics like this one. Plus a new live CEU every Wednesday.
Use this framework when approaching conventional versus progressive dtt | learning | 1 hour in your practice:
Does the data support a need for intervention? Is there a meaningful impact on the individual's quality of life, safety, or access to reinforcement?
YES → Proceed to assessment NO → Document reasoning, monitor
A functional assessment should guide intervention selection. Avoid defaulting to standard protocols without individual analysis. Consider environmental variables, setting events, and private events.
YES → Select evidence-based approach matched to function NO → Complete assessment first
Goals should be co-developed. Assent and informed consent are ethical requirements. The individual's preferences and values matter in selecting both goals and methods.
YES → Proceed with collaborative plan NO → Engage in shared decision-making
This course covers the clinical and ethical dimensions in detail with structured learning objectives and CEU credit.
