Learn more about AC initiatives and provide input on how AC can continue to strive to become a more equitable and welcoming school community.

    • What AC DEIB initiatives are you currently aware of?
    • Do you feel welcome at AC to discuss Diversity, Equity, Inclusion and Belonging Initiatives?
    • If Yes, what/how do you feel welcome?
    • If No, what could the school do differently that would make you feel welcome?
    • How does AC ask you to be involved in DEIB school-based initiatives?
    • Regarding important DEIB school-based initiatives at AC, what would you like us to know that’s important to your family?

    We appreciate you considering these questions ahead of time in preparation for a robust discussion during our November 29th meeting.

    One of Allendale Columbia’s more recent beloved traditions is our annual school-wide Heritage Dinner. We value and honor the diversity of people from all backgrounds and traditions; we also love to celebrate different heritage within our own school community. This special event of unity focuses on inclusivity where students and their families come together to share potluck dinners together.
