When Recipients Become Providers: The Scaling Logic Behind ARC

TL;DR for operators How do you scale a high-touch expert-support service when each central team can serve only so many locations and only within limited geographic reach?

Keeping the initial central hub while allowing supported schools to become local hubs raises that to about 551.
