The Dawson County school board last week approved a measure that will realign grades 6-12 in an effort to open additional opportunities for middle and high school students. In a unanimous 5-0 vote, the board agreed to a plan that would move all sixth and seventh graders to one campus, eighth and ninth graders to a second campus and leave 10th-12th grades at the high school. Planned to be phased in over two years, beginning in fall 2016, the process has been in the works for the last 15-18 months.
