The district's board of education is comprised of nine members who set policy and oversee the fiscal and educational operation of the district through its administration. As a Type II school district, the board's trustees are elected directly by voters to serve three-year terms of office on a staggered basis, with three seats up for election each year held (since 2012) as part of the November general election. The board appoints a superintendent to oversee the district's day-to-day operations and a business administrator to supervise the business functions of the district.

In 2023, parents started a petition calling for the resignation of superintendent Peter Koza, criticizing school leadership’s “slow and inadequate” response to a series of videos which showed a janitor at Elizabeth F. Moore School tampering with cafeteria food. One video showed the janitor rubbing bread meant to be served to students on his intimate parts, while another showed him putting bleach on cucumbers.
