Concord's public schools are within the Concord School District, except for schools in the Penacook area of the city, which are within the Merrimack Valley School District, a district which also includes several towns north of Concord. The only public high school in the Concord School District is Concord High School, which has about 2,000 students. The only public middle school in the Concord School District is Rundlett Middle School, which has roughly 1,500 students. Concord School District's elementary schools underwent a major re-configuration in 2012, with three newly constructed schools opening and replacing six previous schools. Kimball School and Walker School were replaced by Christa McAuliffe School on the Kimball School site, Conant School (and Rumford School, which closed a year earlier) were replaced by Abbot-Downing School at the Conant site, and Eastman and Dame schools were replaced by Mill Brook School, serving kindergarten through grade two, located next to Broken Ground Elementary School, serving grades three to five. Beaver Meadow School, the remaining elementary school, was unaffected by the changes.
