Bush: Tightened standards for teachers, schools and student achievement. Favors vouchers to help some attend private schools.
Kerry: $3.2 billion plan for high school students that would pay for four-year public college tuition. Backed tougher school standards but says emphasis on test scores should be reduced and additional factors considered in measuring progress. Opposes vouchers.
