As Congress began debate last week over the size and scope of more than $120 billion in proposed emergency education aid, state leaders were anxiously awaiting the details so they could make specific plans to spend the economic-stimulus money. Governors, state legislators, and state schools chiefs have yet to learn what rules Congress will attach to any such influx of federal money, which proponents say would help offset losses in state revenues, supplement existing programs, and start a short-term construction program aimed at fighting the recession. The figures may not be final for two weeks or more, and state officials can't nail down their own plans until they know the final dollar amounts and the conditions placed on their use.
