This comparison draws in part from “Creating and Sustaining a Supervised Fieldwork Experience: Perspectives from Supervisors, Graduates, and Students” by Jessica Osos, PhD, BCBA-D, LBA-MI&UT (BehaviorLive), 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 creating and sustaining a supervised fieldwork experience: perspectives from supervisors, graduates, and students, 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 |
|---|---|---|
| What is Measured | Hours-Based: Quantity of supervised time accumulated across task list categories | Competency-Based: Demonstrated performance on specific behavioral benchmarks within each task list area |
| Predictive Validity | Hours-Based: Hours accumulation has moderate correlation with competency development but leaves significant variance unexplained | Competency-Based: Direct performance measurement more accurately identifies candidates who are examination-ready in a clinically meaningful sense |
| Supervisor Workload | Hours-Based: Lower assessment burden; logging hours is simpler than competency evaluation across the full task list | Competency-Based: Higher assessment burden requiring structured observation tools, performance criteria, and regular evaluation contacts |
| Candidate Guidance | Hours-Based: Candidates know how many hours they need but may not know what competencies require development | Competency-Based: Candidates have explicit performance benchmarks that guide their own skill development efforts |
| Ethics Code Alignment | Hours-Based: Meets minimum BACB documentation requirements but may not fully satisfy Section 4.07 evaluation obligations | Competency-Based: More fully expresses Section 4.07 evaluation requirement and supports Section 4.02 adequacy standard |
| Client Protection | Hours-Based: Provides limited assurance that candidates are clinically ready to serve clients without intensive oversight | Competency-Based: Creates a direct link between candidate skill level and supervisory intensity, better protecting client welfare |
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 creating and sustaining a supervised fieldwork experience: perspectives from supervisors, graduates, and students 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.
