    • 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?
