As the school year draws to and end around the Bay, school districts are struggling with finances. Take Brisbane. It’s a small district – only two elementary and one middle school – but its problems provide a window into those faced by districts across the state. For four consecutive years, Brisbane has had to slash its budget due to a lack of funds. Until now, it’s tried hard to shield students from the cuts. But next fall could mark a big change. One principal will go back and forth between the two elementary schools. There may also be more combination classes, for example, with first and second graders in one room. And for first through fifth grade, class sizes may increase to as much as 33, far greater than the 20 to 1 ratio pushed across the state in better times. Watching the school system fall apart is hard for everyone, but for one teacher, it’s personal. Tomorrow, the last day of school, Justine Ferguson will say goodbye to her students and the district, possibly forever. KALW’s Judy Silber has her story.
