A parent asks your website when Friday's early dismissal is. She gets an answer, and the answer is 1:00 PM. Dismissal is at 12:30 PM. Her daughter sits in the main office for half an hour while the secretary calls a phone that's in a purse in a meeting.
That is the fear every superintendent names first, and they're right to name it. A parent who finds nothing calls the school. A parent who finds the wrong thing plans her afternoon around it.
So the measure of an assistant isn't how many questions it answers; it's what it does with the ones it can't. "I don't see that on our website. Here's the main office number." That sentence costs a district nothing and protects everything.
Every vendor will show you the answers. Ask to see the refusals. Ask what the assistant says when a parent asks about a bus stop that was never published, about a rumor going around a class group chat, about a teacher by name. A demo built only from questions it handles well isn't a demo; it's a highlight reel.
A confident machine is easy to build. A careful one takes rules: answer only from what the district has approved, never fill a gap from the open internet, and say plainly when the answer isn't there.
Trust is built by the answers an assistant refuses to invent.
