From The Columbus Dispatch: One of the longest-operating charter-school groups in Columbus, Ohio, will become its own small school district as it opens a fourth school. The addition of Graham Primary School means students will be able to attend a school related to the original Graham School from kindergarten through high school. It's thought to be the first locally based startup to build a kindergarten-to-12th grade network of separate schools in central Ohio. The elementary is to open in fall 2012. The Graham Family of Schools opened Graham Expeditionary Middle School last year and started a second high school, the Charles School, in 2007.
