Which of these is NOT an eligibility requirement for membership on a local board of education?

The requirement of owning property in the district is not necessary for eligibility to serve on a local board of education. Instead, the primary criteria focus on a candidate's status as a registered voter and residency within the district, as well as age requirements. This reflects the understanding that board members are to represent the educational interests of all community members, not solely those who own property. Emphasizing voter registration ensures that board members are accountable to the electorate, while residency guarantees that they are familiar with the specific needs and challenges of the district’s schools. Age criteria, such as being at least 21 years old, ensure that candidates have reached a level of maturity and experience suitable for such a significant role in local governance.
