Discover MDI

A field guide to well-being
in Middle Childhood

We believe there’s strength in numbers.

Positive experiences in middle childhood build the foundation for healthy adolescence and adulthood. Through our partnerships with schools and communities to collect and share rich data through the Middle Years Development Instrument (MDI), we can work to build a future in which all children have the opportunity to truly thrive.

“The MDI provides a 360 degree perspective into a child’s world of social and emotional development, perceptions of school culture and climate, peer and adult relationships, academic experiences and connections to the community. “

–Peter Dubinsky, Burnaby School District
