Washington, D.C. ? The top two lawmakers on the Senate Education Committee said Friday they are putting off consideration of a new No Child Left Behind law until next year.

Sens. Edward M. Kennedy, D-Mass., and Mike Enzi, R-Wyo., have decided that there’s not enough time this year to complete work on the legislation, which has not yet been formally introduced.

The 5-year-old law, up for a scheduled rewrite, requires math and reading tests in grades three through eight, and once in high school. Schools that miss testing benchmarks face increasingly stiff sanctions. The law, originally passed in 2001, is among President Bush’s top domestic policy priorities.

Kennedy, the panel’s chairman, had previously said he wanted a bill before the Senate this year. He now is aiming, however, to bring a bill up for consideration early next year, said his spokeswoman, Melissa Wagoner.

But it might be even more difficult to pass a rewritten No Child bill next year because it is a presidential election year. It is harder to get the bipartisan consensus needed to pass major legislation against the backdrop of an intense presidential campaign.
