When it comes to high school graduation rates, Mississippi keeps two sets of books.
One team of statisticians working at the state education headquarters here recently calculated the official graduation rate at a respectable 87 percent, which Mississippi reported to Washington. But in another office piled with computer printouts, a second team of number crunchers came up with a different rate: a more sobering 63 percent.
The state schools superintendent, Hank Bounds, says the lower rate is more accurate and uses it in a campaign to combat a dropout crisis.
“We were losing about 13,000 dropouts a year, but publishing reports that said we had graduation rate percentages in the mid-80s,” Mr. Bounds said. “Mathematically, that just doesn’t work out.”
Like Mississippi, many states use an inflated graduation rate for federal reporting requirements under the No Child Left Behind law and a different one at home. As a result, researchers say, federal figures obscure a dropout epidemic so severe that only about 70 percent of the one million American students who start ninth grade each year graduate four years later.
