The Dallastown Area School Board Thursday unanimously approved Joshua Doll as the new assistant superintendent of curriculum and instruction.

Doll was most recently Dallastown Area Middle School's principal, and will take over the position immediately. Ron Dyer, who is now the superintendent, most recently held the position.

Doll's contract is for four years starting at $142,000 per year. The board did not announce who will take Doll's position.
