PROVIDENCE — All but one proposal to allow charter schools to expand or open in Providence won approval by the state Council on Elementary and Secondary Education Tuesday night in a three-hour meeting devoted mostly to public comment. Testimonials in favor of the charter schools dominated at first, as parents, staff, former students and the person who would become principal if the proposal was approved were called on in the order they signed up. Each could speak for two minutes, and if the time ran out mid-sentence, the speaker could finish that sentence only. The 19 who spoke in favor of the schools that applied to expand or open in Providence told success stories such as going on to earn a doctorate or getting into an Ivy League college. Parents described the satisfaction of having a choice in how involved they could be in directing their child's education. One described her relief at finally getting help for a child who was falling behind but didn't meet the city's threshold for bringing in services.
