The White House is offering public high schools across the country a chance to win a commencement address by President Barack Obama.

For the second year in a row, the White House is challenging students to demonstrate how their school prepares them for college and a career.

Obama will speak at the winning school's graduation, as he did last year at Michigan's Kalamazoo Central High School.

The contest is part of Obama's Race to the Top education initiative to reform the nation's schools. The White House says more than 1,000 high schools competed in last year's contest.
