Middle childhood is a time in development that is complex and multifaceted. The Middle Years Development Instrument (MDI) is designed to capture this complexity and provide a holistic picture of how children in the middle years are doing at school, at home, and community. The MDI provides valid and reliable information on children in the middle years on five key dimensions: Social and Emotional Development, Physical Health and Well-Being, Connectedness, Use of After-School Time, and School Experiences. Understanding the importance of each of these five dimensions, their roles in supporting positive development during the middle years, and exploring the ways in which these dimensions are interrelated serves as an important foundation for understanding and interpreting MDI data.
