Why is attachment science important for educators?

First relationships with educators provide foundational experiences that shape children's capacity for lifelong learning, emotion regulation, and social connection. These early classroom relationships become the template for how children approach learning, handle challenges, and form future connections at school.

When teachers understand attachment science, they are able to create secure classroom environments where children feel safe to both seek connection and also to explore and develop essential social-emotional competencies. Research shows children with secure educator relationships demonstrate enhanced emotional regulation, improved social skills, greater learning confidence, increased resilience, and stronger foundations for future relationships.

For young children, relationships in early care settings may be the first important relationship they have with someone outside of their home. The Circle of Security recognizes the role of an educator extends beyond instruction—they serve as attachment figures who profoundly impact a child's developmental trajectory through relationship quality.

What will I learn in COS Classroom Foundations?

The course helps educators understand how to apply attachment theory to group care settings, focusing on relationship-building strategies that support individual children's needs and classroom-wide social-emotional learning. COS Classroom also engages the ancestral wisdom of educators in a reflective process that taps into the wisdom of a committed educator to find caring ways to make a difference.

COS Classroom Foundations focuses specifically on the attachment relationship between educator and child as the foundation for all learning. Rather than teaching discrete social-emotional skills, this approach helps children develop internal capacity for regulation and connection through secure relationships with teachers.

Circle of Security Classroom isn’t meant to replace your classroom curricula, but rather it’s foundational and leads to the success of other curriculum. To say this another way, can you imagine trying to make any curriculum work in the classroom if you don’t have secure attachment as a foundation with children? When children feel held in a safe and secure relationship, you can’t stop them from learning and developing lifelong capacities.

Many classroom models tend to assume that there’s a secure relationship with the teacher. We know that’s not always true. In fact, many early care professionals come from histories of trauma, and may struggle to trust that relationships are safe. And many children come with a history that makes it difficult for them to trust adults.

The overall goal of Circle of Security Classroom is to enhance or even develop security in relationships between teachers and children. It’s hard for any classroom program to work if teachers and children don’t trust the relationship.

COS Classroom Foundations creates positive outcomes for both children and educators by transforming classroom relationships and supporting teacher wellbeing through deeper understanding of attachment dynamics.
