A new Republican proposal reauthorizing No Child Left Behind has left U.S. Secretary of Education Arne Duncan worried about large school districts with large numbers of Hispanic and black students.

Duncan said that these schools "could lose more than $3 billion in federal funding over the next six years under the Republican plan," according to an article on NYTimes.com.

The House, the article said, " is expected to pass a plan this week that would cut back federal regulation of education from kindergarten through 12th grade and give state and local authorities more discretion over everything from assessing teacher and student performance to the flow of Title I money, the largest stream of federal funding for low-income students."

Duncan released new data this week that "he said showed that the plan could be detrimental to school districts with a high percentage of low-income students, which receive extra money under the current law. Under the proposed law, states could let students take their funding to the public school of their choice, an approach known as portability."

“If you look at the numbers, it’s a pretty devastating portrait of what could happen,” Duncan said in the article. “Detroit could lose $265 million, L.A. three-quarters of a billion. If you go district by district, you get some idea of the severity.”

Representative John Kline, however, said that Duncan's numbers were "scare tactics," according to the article. "He said that portability would be an option, not a requirement, and that Mr. Duncan’s figures were based on the premise that President Obama’s proposed budget would go into effect."
