answer:I’d start with neighborhoods and families, and find out what is important to them and how to interest them in such a school, and what they would need in order to enroll their children. Far too often “gifted” schools end up filled with kids from middle or upper class families, because these families have the cultural and economic capital to see such schools as valuable, and to support their children the whole way through. (In my experience in the United States.) I was in a gifted/accelerated program through junior high and high school, and by the time my cohort graduated, almost all of the kids from poor families had already dropped out. It was sad and all too predictable, the way things go in the States.
