Therapist consistency directly shapes ABA outcomes. Learn how frequent RBT changes slow progress — and how Achieve BT's low turnover protects your child.

A continuity-of-care policy in ABA therapy is a formal, documented plan that ensures a child's treatment continues without disruption when a therapist leaves, takes leave, or transitions off a case. It includes overlap coverage, data transfer protocols, BCBA-supervised handoffs, and family communication. The BACB Ethics Code (Section 3.14) requires all certified behavior analysts to have a plan in place for both planned and unplanned service interruptions. Without one, children risk regression, behavioral setbacks, and weeks of lost progress. Most ABA parents ask about hours, insurance, and wait times. Few think to ask: what happens to my child's therapy if our therapist leaves? It's a fair question. Industry data puts annual RBT turnover at 65% (BHCOE Accreditation, 2022). That means therapist transitions aren't exceptional — they're routine. The question isn't whether a change will happen. It's whether your provider has a plan when it does. That's exactly what a continuity-of-care policy addresses. What Is a Continuity-of-Care Policy in ABA Therapy? A continuity-of-care policy is a documented set of protocols that governs what happens to a child's ABA therapy when service is interrupted — planned or unplanned. It is not a general promise of good care. It is a written, clinical plan embedded in the service agreement from the start. In practice, a strong continuity-of-care policy in ABA covers: A general plan of action for service interruptions, included in the initial service contract Defined timelines for notifying families when a therapist transition is occurring A structured overlap period — where the departing and incoming therapist work together with the child Transfer of session data, behavioral baselines, and program documentation to the new RBT BCBA oversight during the transition to ensure goal consistency Documentation of all actions taken and outcomes after the interruption It's Not Just Good Practice — It's an Ethical Requirement This isn't optional for accredited ABA providers. The Behavior Analyst Certification Board (BACB) Ethics Code , Section 3.14, requires that behavior analysts "act in the best interests of the client to avoid interruption or disruption of services." It specifically mandates that: Service agreements include a general plan for service interruptions BCBAs make timely efforts to facilitate continuation of services for both planned interruptions (relocation, temporary leave) and unplanned interruptions (illness, funding disruption, emergencies) All actions and outcomes during a service interruption are formally documented Sections 3.15 and 3.16 further govern appropriate discontinuation and transition of services, requiring documented justification and structured transition support in both cases. The BACB also published a dedicated Continuity of Services Toolkit to help providers build these systems. It remains one of the clearest articulations of what compliant, ethical transition planning looks like in clinical practice. What Happens Without One The clinical consequences of an unmanaged therapist transition are well-documented. Research cited by Teamwork and Token Data Lab found that when a child experiences two or more RBT changes in a year, measurable progress drops by over 50%. Skill regression during gaps in service is consistently identified in ABA literature as one of the primary risks of high therapist turnover. A meta-analysis referenced by Praxis Notes found that only 66% of children who start ABA therapy remain after 12 months — and 13% of referred children never start services at all due to disruptions. Lapses don't just delay progress. They actively erode it. For children with autism, where predictability and consistent behavioral support are foundational to progress, an unplanned therapist change with no bridge protocol can trigger: Behavioral regression on previously mastered skills Increased challenging behaviors during the adjustment period A reset of the trust and rapport needed for effective therapy sessions Gaps in BCBA-supervised data collection, weakening the clinical picture What a Strong Continuity-of-Care Policy Actually Looks Like  Here's what parents should expect to see — in writing — from any ABA provider they're evaluating:
