- A trustee is an elected member of a local school board who helps govern a public school district.

- Trustees represent community interests and are responsible for setting policies that guide how the school district operates.

- The board of trustees hires and evaluates the superintendent, who manages the day-to-day operations of the district.

- Trustees approve the district’s budget, monitor spending, and may set the local tax rate or call for bond elections to fund schools.

- The board also oversees educational programs, district goals, and overall performance.

- In Texas, trustees are elected to four-year terms, often on a rotating basis, so not all seats are elected at the same time.

- Trustees serve without financial compensation.
