MEMPHIS, Tenn. (AP) - Voters have selected school boards in six Shelby County suburbs as they continue the process of breaking away from the Unified School District and starting their own public school systems. The Commercial Appeal (http://bit.ly/1av0akl ) reports 32 school board members won seats in Thursday's elections in Arlington, Bartlett, Collierville, Germantown, Lakeland and Millington. In July, voters in each municipality overwhelmingly approved separate school systems. The suburbs were sued by the Shelby County Commission and the city of Memphis after announcing intentions to avoid the merger between the county and city school systems. The merger created the Unified School District, which began operating in August with 150,000 students. The unified district could lose about 25,000 students when the municipalities start their own systems as early as next year.
