Louisiana’s high school graduation rate grew by an average of 2.33 percent between 2006 and 2010, the second-highest growth rate in the nation, according to a report released Monday by Civic Enterprises, the Everyone Graduates Center at Johns Hopkins School of Education, America’s Promise Alliance and the Alliance for Excellent Education.

The report found that for the first time the United States is on track to meet the goal of graduating 90 percent of high school students by the class of 2020. Only Wisconsin and Vermont already have 90 percent graduate rate.

Louisiana high schools graduated 68.8 percent of students in 2010, according to the study.

Louisiana also sharply reduced the number of “dropout factories,” schools where the number of 12th graders is 60 percent or lower than the number of ninth graders. Louisiana closed 24 of these schools between 2006 and 2010, according to the study.
