What is the Toddler Development Instrument (TDI)?

The Toddler Development Instrument (TDI) is a questionnaire for parents and caregivers of children aged 12 – 24 months old that asks about the early experiences and environments of the children, their caregivers, and their families. The TDI includes questions about family, home and community environments, as well as the supports and barriers families experience within these environments.

Currently, in British Columbia, there is no system to regularly collect and share information on children’s experiences in the early years before children enter the school system in kindergarten. The Toddler Development Instrument (TDI) is a tool that aims to fill this gap. We are currently piloting the TDI in BC with the aim to gather population-level data in each of the five pilot communities. Pilot communities include Richmond, Revelstoke, Powell River, Kootenay-Columbia region and a joint initiative between Campbell River and Comox Valley.

The long-term goal is to link TDI information with HELP’s other monitoring tools such as the Childhood Experiences Questionnaire, the Early Development Instrument and the Middle Years Development Instrument so that we can understand which social factors make a difference in children’s development. Collectively, we anticipate that these tools will help us understand how we can build a more supportive system in early childhood that will help all children and families thrive.
