This comparison draws in part from “Supervision CSI: Investigate, Analyze, Solve” by Nicole Stewart, MSEd, BCBA, LBA-NY/NJ (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 →Most ABA supervisors were supervised using some version of the topic-based model: each week covers a different area of the task list, trainees ask questions about current cases, and the supervisor offers clinical guidance. This approach has intuitive appeal — it ensures broad content coverage and keeps supervision conversations grounded in real cases. But it has a significant limitation: it does not systematically assess whether trainees can actually perform the skills being discussed. A trainee can engage thoughtfully in a conversation about shaping procedures without being able to implement shaping correctly in a session.
Data-based supervision — the framework underlying the CSI model — treats each supervision contact as both a training opportunity and an assessment event. The supervisor collects observational data, reviews permanent products, and probes clinical reasoning before, during, and after supervision meetings. Training activities are selected based on identified gaps, not scheduled topics. Progress is measured against specific behavioral criteria.
The comparison below examines key dimensions where these two models diverge, with particular attention to the outcomes most relevant to BCBA supervisors: trainee skill acquisition, client outcomes, exam readiness, and regulatory compliance.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| How performance gaps are identified | Topic-based: Gaps surface reactively — through trainee self-report, client outcome problems, or supervisor observation during routine case review | Data-based (CSI): Gaps identified proactively through systematic multi-source assessment — observation data, permanent product review, and structured probes |
| Supervision agenda structure | Topic-based: Agenda follows a predetermined content schedule or is driven by trainee questions; topics rotate regardless of whether previous topics have been mastered | Data-based (CSI): Agenda is generated from data collected since last meeting; agenda items map to specific trainee behavior targets with explicit criteria for success |
| Feedback specificity | Topic-based: Feedback tends to be evaluative and impressionistic — 'your session notes need more detail' or 'good work with the prompting hierarchy' | Data-based (CSI): Feedback is anchored to specific observable data — frequency counts, fidelity percentages, task list item-level performance records |
| Training method selection | Topic-based: Training activities (discussion, review, case consultation) are often selected based on convenience or trainee preference rather than matched to the type of skill gap | Data-based (CSI): Training method matched to gap type — BST for skill acquisition deficits, modeling and rehearsal for fluency deficits, case conceptualization probes for analytic deficits |
| BACB compliance documentation | Topic-based: Documentation often records topics covered and hours completed; less likely to include specific trainee behavior data or measurable progress indicators | Data-based (CSI): Documentation includes observation data, competency tracking matrices, meeting notes with specific targets and criteria — fully defensible against BACB audit |
| Generalization of trainee skills | Topic-based: Skill generalization is assumed rather than assessed; trainees may perform well in discussion but inconsistently in the field | Data-based (CSI): Generalization is explicitly assessed through observation across multiple settings and clients; generality deficits are treated as a distinct training target |

Use this framework when approaching supervision csi: investigate, analyze, solve 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.
