In 2012, the Washington Township Educational Coalition filed a petition with the Court of Common Pleas of York County, Pennsylvania, to initiate the process of transferring Washington Township from the Dover Area School District to the Northern York County School District. The petitioners cited the superior education outcomes and lower property taxes in Northern County School District as motives for the change request. Estimates project a net gain of $800,000 to $1 million over the next five years to Northern York County School District if the change were approved. After initially denying the petition in March 2017, the State Board of Education issued an order on March 10, 2021, transferring Washington Township to the Northern York County School District effective with the 2021-2022 school year.
