California's largest teachers union will back a fight in court to overturn the state's new eighth-grade algebra requirement. The state board "acted abruptly, imprudently and without fully understanding the consequences of its actions on our schools, teachers and students," said David Sanchez, president of the 340,000-member association. "For our schools to begin now to prepare all eighth-graders to take the Algebra 1 exam, they must immediately hire about 3,000 more teachers and properly train about a thousand more who are either underprepared or teaching in another field."
