PORTLAND -- New numbers showed the on-time graduation rate for Oregon high schools rose one percent from 2010, to 67 percent.

But more than 11,000 students in the Oregon high school class of 2011 dropped out, and Governor John Kitzhaber called that number unacceptable.

The graduation rate for Portland schools increased by five percent, but the city s 59 percent graduation rate was still among the worst in the state.

State school superintendent Susan Castillo celebrated an increase in the state's on-time graduation rate, and other educators tried to focus on the biggest areas of improvement.

The biggest increase in Portland was at Roosevelt High School, in the St. Johns neighborhood. But even though the school saw a 14-point improvement, only 51 percent of its students earned diplomas in four years.

School districts with more than 300 students that had the best graduation rates in the state were Lake Oswego, West Linn-Wilsonville and Sherwood.
