Welcome to the MDI Administrator Portal, where you can find instructions and resources to guide you through the process of administering the MDI.
Thank you for working with us this 2024-25 school year! MDI School District Reports 2024-2025 will be made available here end of April.
In addition to annual school and school district reports, visit the MDI Data Dashboard – a new an online, interactive tool which allows you to view Neighbourhood profiles and maps, and explore trends in MDI data over the last six years.
We encourage you to explore Discover MDI – the Field Guide for the Middle Years Development Instrument. It is a powerful tool to understand and support children’s well-being and positive development in the middle years. Discover MDI guides you on your journey with the MDI—from understanding the MDI and its importance in middle childhood, to collecting, exploring, and sharing MDI data, to using MDI data to catalyze action to improve the mental health, well-being, and resilience of children in the middle years.
Hear stories from colleagues in the school system who’ve found success with the MDI.
