The Network has an annual conference for its leaders. The annual conference takes place in May of every year and brings in leaders of the 19 Inclusive Education Resource Centres, the board of governors of the 19 IERCs and development partners. Leaders of the institutions lead spiritual activities as well as planning and review the programs for future development.
