School officials have released a directory of school assignments for the 2013-2014 academic year. The assignments are based on the redistricting plan adopted by the Winchester School Committee on Nov. 5. The map-based plan will shuffle hundreds of the town’s youngest students by shifting school boundary lines. Under the plan, as many as 215 of the town’s 2,219 elementary students will attend new schools next September. To view the directory, visit winchesterredistricting.com.
