The Center for Education Reform has devised a method that it says measures the amount of influence that states allow parents to have in the education of their children.
The center says the Parent Power Index "measures the ability in each state of a parent to exercise choices...engage with their local school and board, and have a voice in the systems that surround their child." The index takes into account access to charter schools, school choice and online learning; the level of teacher quality, and the transparency of education data.
