CHICAGO - President Bush warned Congress that if lawmakers try to weaken his No Child Left Behind law, he'll veto the legislation.
And, he said if Congress doesn't reauthorize the law, he'll make as many changes as he can on his own, such as providing extra help for struggling schools, and devising an accurate system for measuring high school dropout rates.
Speaking at a Chicago elementary school, the president said he wants to ensure "that a high school degree means something."
The top Democrat and Republican on the Senate Education Committee have said they would put off rewriting the six-year-old law until later this year.
There is broad agreement that changes should be made, including encouraging schools to measure individual student progress instead of using snapshot comparisons of grade levels.
