For three years, Bozeman has been sharing with non-attendees at "A Taste of AGATE" event.

We invite parents and teachers of gifted kids.
We take reservations via Eventbrite. We have learned the hard way to require payment upfront, even though that means we have to increase the price a bit. If we don't, we end up with no-shows, and we still have to pay for their dinners.
We make sure we have at least 2-3 people who attended AGATE. Each one is asked to share for 10 minutes about key insights they obtained from 2-3 breakout sessions.
It's a real easy event to put on and it gives parents a chance to get to know our GT Coordinators and some teachers, as well as connect with others. We usually ask what topics they would like to have additional presentations on during the year or if there are issues that the parents want to work on.
