A bipartisan group of U.S. senators is pledging to work together to revamp the federal No Child Left Behind education law, a day after President Barack Obama called on lawmakers in his State of the Union address to speed up overhaul of the Bush-era policy.

Senate education committee chairman Tom Harkin said he hopes to have a bill to Obama by the end of the summer.

The law has been credited with raising reading and math scores, but it has also tagged more than a third of U.S. schools as failing and created a hodgepodge of sometimes weak academic standards.

Harkin and the Obama administration say the top priority is to move away from punishing schools that don't meet federal benchmarks and instead to focus on rewarding schools for progress.
