The New York Times profiles how early college high schools--five-year, free programs that allow students to complete high school plus two years of college credit--are doing exceptional things to revitalize and concentrate our baggy, inefficient standard educational model:

Until recently, most programs like this were aimed at affluent, overachieving students -- a way to keep them challenged and give them a head start on college work. But the goal is quite different at SandHoke, which enrolls only students whose parents do not have college degrees.

Here, and at North Carolina's other 70 early-college schools, the goal is to keep at-risk students in school by eliminating the divide between high school and college.

"We don't want the kids who will do well if you drop them in Timbuktu," said Lakisha Rice, the principal. "We want the ones who need our kind of small setting."

Results have been impressive. Not all students at North Carolina's early-college high schools earn two full years of college credit before they graduate -- but few drop out.

"Last year, half our early-college high schools had zero dropouts, and that's just unprecedented for North Carolina, where only 62 percent of our high school students graduate after four years," said Tony Habit, president of the North Carolina New Schools Project, the nonprofit group spearheading the state's high school reform.

In addition, North Carolina's early-college high school students are getting slightly better grades in their college courses than their older classmates.

While North Carolina leads the way in early-college high schools, the model is spreading in California, New York, Texas and elsewhere, where such schools are seen as a promising approach to reducing the high school dropout rate and increasing the share of degree holders -- two major goals of the Obama administration.

More than 200 of the schools are part of the Bill and Melinda Gates Foundation's Early College High School Initiative, and dozens of others, scattered throughout the nation, have sprung up as projects of individual school districts.

"As a nation, we just can't afford to have students spending four years or more getting through high school, when we all know senior year is a waste," said Hilary Pennington of the Gates Foundation, "then having this swirl between high school and college, when a lot more students get lost, then a two-year degree that takes three or four years, if the student ever completes it at all."

Most of the early college high schools are on college campuses, but some stand alone. Some are four years, some five. Most serve a low-income student body that is largely black or Latino. But all are small, and all offer free college credits as part of the high school program.

"In 27 years as a college president, this is just about the most exciting thing I’ve been involved in," said Rick Dempsey, the president of Sandhills. "We picked these kids out of eighth grade, kids who were academically representative at a school with very low performance. We didn't cherry-pick them. Their performance has been so startling that you see what high expectations can do."

"The first year, I didn't like it, because my friends at the regular high school were having pep rallies and actual fun, while I had all this homework," one student says. "But when I look back at my middle school friends, I see how many of them got pregnant or do drugs or dropped out. And now I'm excited, because I'm a year ahead."
