A five-year extension of the sales, personal income and vehicle taxes enacted two years ago is the cornerstone of Brown's plan to close a $26 billion deficit. However, many GOP leaders oppose the plan.
Monday, hundreds of teachers, parents and public-school workers rallied at the state Capitol.
They're urging lawmakers to approve Brown's budget plan and let voters decide if recent tax increases should be extended.
Teachers say any more education cuts will only result in larger class sizes and a shorter school year.
So far, Republicans are refusing to put the issue before voters.
