The year 2016 marks the 10th anniversary of the "Education Next" poll on K-12 education policy, offering "Education Next" the opportunity to take a retrospective look at public opinion on this vital topic. In 8 of the past 10 years, "Education Next" has also surveyed teachers on the subject and has seen some interesting differences between the thinking of these educators and the public at large. This year, given that public opinion on many national issues is riven by partisan disparities, the authors compare and contrast the views of Republicans and Democrats. On many topics, the authors find that opinion has remained consistent over the past 10 years. The authors write that they see only slight changes in people's views on the quality of the nation's schools, for instance, or on federally mandated testing, charter schools, tax credits to support private school choice, merit pay for teachers, or the effects of teachers unions. But on other issues, opinions have changed significantly. Support for the Common Core State Standards has fallen to a new low in 2016. So has public backing for school vouchers--both those limited to low-income families and those made available to all families. Support for tenure has fallen, but approval for teacher salary hikes has climbed to levels not seen since the U.S. recession of 2008 among respondents not told about current salary levels. Over all, the authors present details of their seven main conclusions drawn from their multi year survey of public and teacher opinions on a broad range of educational issues.
