President Obama has said we need to replace No Child Left Behind with a law that’s “more flexible and focused on what’s best for our kids.” Sunday marks the 10 year anniversary of the legislation.

Sunday marks the anniversary of one of the biggest school reforms of recent years. Ten years ago this weekend President George Bush signed the No Child Left Behind Act into law. It delivered big changes to public school testing and standards. But it has polarized educators and activists across the country. President Obama is urging Congress to reauthorize it with few significant changes. KPCC's Adolfo Guzman-Lopez reports.
