Tennessee students are making their way from the back of the class.Gov. Bill Haslam announced Thursday that Tennessee had the largest academic growth of any state in the nation in 2013 based on one standardized test score.The National Assessment of Education Progress (NAEP) says Tennessee had the largest growth of any state during a single testing cycle since it began this test a decade ago.NAEP refers to itself as the nation’s report card, assessing students in reading and math. Students in all 50 states have taken NAEP since 2003.“These historic gains are a result of years of hard work by a lot of people across Tennessee – our teachers, students, principals, superintendents, parents, lawmakers, school board members, business leaders, and many others,” Haslam said.
