And four years ago, we started Race to the Top -- a competition that convinced almost every state to develop smarter curricula and higher standards, all for about 1 percent of what we spend on education each year. Tonight, I'm announcing a new challenge to redesign America's high schools so they better equip graduates for the demands of a high-tech economy. And we'll reward schools that develop new partnerships with colleges and employers, and create classes that focus on science, technology, engineering and math -- the skills today's employers are looking for to fill the jobs that are there right now and will be there in the future.
