The education debate pits more federal control and number of years of available public education against increased local control and more school choice in the form of charter schools and vouchers. Most candidates agree teachers should be paid more and treated like professionals in exchange for greater accountability. The landmark No Child Left Behind law, passed in 2002 with the compromise of greater funding in exchange for testing and accountability at the federal has served as the backdrop for the debate. Candidates are also talking about improving college affordability.
