This comparison draws in part from “Train, Sustain, Maintain: Strengthening Supervision and Consulting Services in Schools” by Danielle Buse, BCBA, LBA (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 →School-based BCBAs face a fundamental service delivery decision: should behavioral expertise be delivered primarily through direct service — the BCBA working directly with students to implement behavior plans and skill programs — or through a consultative model — the BCBA coaching, training, and supporting the school staff who work with students throughout the day? In practice, most school-based BCBAs use a combination, but the ratio of direct to indirect service time reflects strategic choices with significant consequences for the reach, sustainability, and system-level impact of behavioral services.
The direct service model produces high implementation fidelity during BCBA contact time but is limited in scale — one BCBA can have direct contact with only a finite number of students per week — and does not build the staff competency that sustains behavior change after the BCBA's involvement ends. When direct service is the primary modality, student outcomes are contingent on BCBA access, and the school develops no independent capacity for behavioral problem-solving.
The consultative model extends the BCBA's impact by working through staff who are with students throughout the school day. It builds genuine organizational capacity, produces more generalizable student behavior change because interventions are implemented in all relevant settings and by all relevant staff, and is sustainable across transitions in BCBA staffing. The trade-off is fidelity risk: consultation produces outcomes only to the extent that staff implement coached procedures with adequate fidelity, which requires effective coaching and ongoing feedback systems.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Primary service mechanism | Direct Service: BCBA works directly with students to implement behavior plans and skill programs | Consultative Model: BCBA coaches and trains staff who implement behavior support throughout the school day |
| Scale of impact | Direct Service: Limited to students with direct BCBA contact time; does not scale across the building | Consultative Model: Extends to all students whose staff receive coaching; scales across classrooms and buildings |
| Implementation fidelity | Direct Service: High fidelity during BCBA contact; uncertain fidelity when BCBA is not present | Consultative Model: Variable fidelity dependent on coaching quality and staff competency; requires ongoing monitoring |
| Sustainability of outcomes | Direct Service: Outcomes contingent on ongoing BCBA involvement; limited sustainability after service ends | Consultative Model: Outcomes embedded in staff repertoires and school systems; sustainable across BCBA transitions |
| Capacity building | Direct Service: Does not build school staff's independent behavior-analytic repertoires | Consultative Model: Builds staff competency that serves students beyond the current BCBA's involvement |
| Appropriate student population | Direct Service: Students with high-complexity needs requiring intensive, expert-delivered intervention during acute phases | Consultative Model: Students at all need levels; most effective as primary modality for Tier 2 and Tier 3 support |

Use this framework when approaching train, sustain, maintain: strengthening supervision and consulting services in schools 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.
