When teachers Bryan Grau and Debora Gil R. Casado pitched an idea in 2002 to start a charter school in Madison that would teach classes in both English and Spanish, they ran into resistance from school administrators and their own union. Grau and his cohorts were asked to come up with a detailed budget for their proposal, but he says they got little help with that complex task. He recalls one meeting in particular with Roger Price, the district’s director of financial services.
“We asked for general help. He said he would provide answers to our specific questions. We asked where to begin and again he said he would answer our specific questions. That’s the way it went.”
Ruth Robarts, who was on the Madison School Board at the time, confirms that there was strong resistance from officials under the former administration to the creation of Nuestro Mundo, which finally got the green light and is now a successful program that is being replicated in schools around the district.
“First they would explain how the existing programs offered through the district were already doing a better job than this proposal, and then they would show how the proposal could never work,” says Robarts. “There seemed to be a defensiveness towards these innovative ideas, as if they meant the district programs were somehow lacking.”
The Madison School District “has historically been one of the most hostile environments in the state for charter schools, especially under Superintendent Rainwater,” adds John Gee, executive director of the Wisconsin Association of Charter Schools.

Madison continues to lag other Districts in terms of innovative opportunities, such as Verona’s new Chinese Mandarin immersion charter school.
