The Equity from the Start team is part of the Offord Centre for Child Studies at McMaster University. Our focus is on children’s holistic developmental health in the early years of life. One of our main priorities as a team is collecting and conducting research using the Early Development Instrument (EDI) across Canada in collaboration with our partners.

The Early Development Instrument

The Equity from the Start team works with partners to implement the Early Development Instrument both nationally and internationally. The EDI is a questionnaire completed by kindergarten educators which measures children’s ability to meet age appropriate developmental expectations.
