Secretary of Education Arne Duncan went on NPR yesterday and told Melissa Block that his two young kids will attend a D.C. public school. “There are great, great schools (in D.C.),” Duncan said. “We feel very confident they’ll be able to get a great education here.” There was some criticism lobbed at the Obamas for choosing a hoity toity D.C. private school for their girls, but you could at least make the argument that a desire for continuity prevailed in both families: the Duncan kids attended public schools in Chicago, while the Obama girls were in a private one. Interestingly, though, Duncan made his remarks right after the Obamas stopped by a D.C. public charter school to read to some second graders and sing the school’s praises. Think Duncan’s promise to send his kids to a “public” school could actually mean public charter?
