Washington ? The nation’s governors offered an alarming account of the American high school Saturday, saying only drastic change will keep millions of students from falling short.

“We can’t keep explaining to our nation’s parents or business leaders or college faculties why these kids can’t do the work,” said Virginia Democratic Gov. Mark Warner, as the state leaders convened for the first National Education Summit aimed at rallying governors around high school reform.

The governors say they want to emerge today with specific plans for enacting policy, weary of statistics showing that too many students are coasting, dropping out or failing in college.

The high school summit drew at least 45 governors from the 50 states and five U.S. territories, along with top names in U.S. industry and education.

Most of the summit’s first day amounted to an enormous distress call, with speakers using unflattering numbers to define the problem. Among them: Of every 100 ninth-graders, only 68 graduate high school on time and only 18 make it through college on time, according to the National Center for Public Policy and Higher Education.

The most blunt assessment came from Microsoft chief Bill Gates, who has put more than $700 million into reducing the size of high school classes through the foundation formed by him and his wife, Melinda. He said high schools must be redesigned to prepare every student for college.

“America’s high schools are obsolete,” Gates said. “By obsolete, I don’t just mean that they’re broken, flawed or underfunded, though a case could be made for every one of those points. By obsolete, I mean our high schools — even when they’re working as designed — cannot teach all our students what they need to know today.”

The summit is the governors’ fifth on education, but the first devoted to high schools. The original governors’ education summit, organized by the first President Bush in 1989, is credited with spurring a movement of basing student performance on higher standards.
