During this 1-Day Workshop, participants will gain strategies for how to build better parent engagement and collaboration with your school community to better support all of your students. Each participant will learn about a “Parentship” and how to purposely build a guiding coalition to move this work forward in their schools. Participants will also be given several easy-to-implement strategies for their own collaborative teams and school communities along with time and tools to think through that process.

In this session, participants will explore innovative strategies and practical tools designed to challenge advanced learners through extended and personalized learning opportunities. Attendees will examine how flexible grouping, tiered assignments, and student choice can transform their classrooms into dynamic spaces that promote deep engagement and continuous learning. By embedding these strategies into their PLC processes, participants will leave equipped to elevate their team's impact on all students.
