What Implementation Science Tells Us
Research from the National Implementation Research Network (NIRN) quantifies what many practitioners already sense. Training alone, without follow-on coaching and reflective support, yields between 5 and 10 percent actual practice change in real-world delivery settings. When training is paired with structured coaching and sustained reflective practice, successful implementation rises to 80 to 90 percent.

The California Evidence-Based Clearinghouse maps this directly. Its implementation framework distinguishes between the exploration and adoption phases, when an organization selects and trains in a model, and the implementation phases, when the model is delivered with fidelity. The framework identifies three conditions that determine whether implementation succeeds: implementation leadership, or organizational commitment to the model; implementation climate, meaning structures that support ongoing practice; and the sustained use of fidelity tools to monitor delivery quality over time.
The CEBC program entry for Circle of Security Parenting notes specifically that the model relies on trained facilitators holding space for caregivers to reflect on attachment needs and relationship struggles (Shark Music™), and to offer emotion regulation. These capacities do not maintain themselves. They require ongoing support to hold.
Across COS Parenting™, COS Classroom™, and COS Intensive™, initial training is designed to accomplish the first phase. The conditions for the second phase of implementation have to be built separately.
Why Relationship-Based Work Requires Reflective Support
Parallel process is a foundational concept in infant and early childhood mental health and in attachment-focused intervention. It describes how the relational dynamics present in a facilitated or clinical relationship tend to replicate at every level of a system: between client and practitioner, between practitioner and supervisor, between supervisor and organization.
Parallel process means that practitioners require the same conditions they are expected to provide. A COS Parenting™ facilitator, a COS Classroom™ Coach, and a COS Intensive™ clinician are each being asked to offer a holding environment, a Secure Base™ and Safe Haven™, for the caregiver. That environment does not emerge automatically from training. It is built through the relationship, and it requires intentionality.
The holding environment available to clients depends, in part, on the holding environment offered to the practitioner.
Without access to reflective community, peer consultation, or expert support, practitioners carry alone what the work brings to them.
What Practitioners Are Already Telling Us
What practitioners told us
A survey of more than 800 COSP™ facilitators, immediately following training
1 in 3
named the loss of their training cohort as the primary gap after completing training
1 in 5
explicitly asked for a way to continue or deepen the work
The language they used is specific:
"It would be great if people had access to others practicing COS in their local area so they can connect and perhaps co-facilitate together."
"I honestly wish the live sessions were longer. I would have loved to dive deeper."
"I would love to go through this course with other facilitators online with a lecturer."
These were signals that we needed to create a formal implementation support program for our practitioners.
The Consequences of Working Without Support
Research from the Office of Planning, Research and Evaluation (OPRE) documents what happens when reflective support is absent. Practitioners report decreased self-efficacy, lower job satisfaction, and increased vulnerability to secondary traumatic stress, findings that hold across relationship-based disciplines and delivery settings.
When COS practitioners lack structured support after initial training, two patterns tend to emerge. The first is model drift, where the reflective and relational orientation of the model is gradually replaced by behavioral problem-solving, not because practitioners have forgotten their training, but because holding a different orientation requires ongoing reinforcement to maintain under the pressure of real caseloads and complex family dynamics.
The second is practitioner attrition, in which capable, well-trained practitioners leave the work not because they are poorly suited to it, but because the conditions for sustaining it were never established. The clients and families those practitioners served lose access to something that is difficult to replace.
myCOS™ Premium: COSI's Formal Implementation Support Program
myCOS™ Premium is COSI's formal implementation support program for practitioners across all three COS pathways: COS Parenting™, COS Classroom Coach™, and COS Intensive™. It is built to sustain the ongoing work of delivering the model with fidelity across real caseloads, complex dynamics, and the full range of what practitioners encounter in the field.
