What defines a trust school?

A trust school is defined as a type of school in the UK that is supported by a charitable trust. This charitable support typically enhances the school's capabilities by providing additional resources, funding, and development opportunities. Trust schools have more freedom over their curriculum and can foster innovative practices due to the backing of a charitable organization. This relationship allows trust schools to pursue specific objectives or educational philosophies that align with the ethos of the trust.

The other options do not accurately capture the essence of what defines a trust school. While trust schools do operate within the public sector, they are not solely dependent on government funding; instead, they combine this with funds and support from the associated charitable trust. Furthermore, trust schools are not simply public schools without specifications, nor are they governed entirely by parents. Though they may have some parental influence, the governance structure typically involves a broader range of stakeholders, including the trust itself and education professionals.
