Discover MDI

A field guide to well-being
in Middle Childhood

We believe there's strength in numbers.

Middle Childhood is a fascinating time of development and change, and positive experiences during the years from 6 to 12 can build the foundation for healthy adolescence and adulthood.

By collecting and sharing rich data about this period through the Middle Years Development Instrument (MDI), we believe we can make informed choices to ensure that all children have the opportunity to truly thrive.

Let the data lead you to discovery

This Field Guide will walk you through the steps to start making sense of your MDI data and start making change in your community.
