The document describes the Grand Erie Catholic District School Board's system-wide approach to collaborative inquiry. It began in Year 1 by focusing on literacy with select schools. In Year 2, all elementary schools participated with a focus on assessment. For Year 3, all elementary and secondary schools took part in a process-based collaborative inquiry model centered around improving student learning. Emerging themes showed an alignment between school and system efforts, increased teacher collaboration, and teams valuing the inquiry process for reflecting on practice and student needs. The board plans to continue this approach going forward.
