Which of the following services is NOT generally managed by district councils?

District councils typically have a range of responsibilities aimed at serving their local communities, including managing cemeteries, planning and environmental health services, as well as recreational services like swimming pools and leisure facilities.

The management of education, however, falls primarily under the jurisdiction of county councils or unitary authorities. These entities are responsible for overseeing education at a broader level, which includes setting policies and funding for schools within their areas. While district councils may be involved in certain educational initiatives or facilities at the local level, they do not hold the primary responsibility for education services.

Understanding this distinction clarifies the reason why education is the correct answer as the service not generally managed by district councils.
