Historically the church has been involved in areas of education and setting up and resourcing schools. The church saw a need and did something about it. In some areas there are still such legacies from the past, parochial charities and trusts that offer grants to the needy of the parish. Frequently, the local clergy are the trustees.
Schools today often have very tight budgets and any extra sources of income are welcome. Schools don't always know that these historic local church charities exist. Churches can be proactive, informing schools about them and encouraging them to make an application if they have a need which meets the criteria.
In some circumstances, churches can support a school in making an application to a national Christian trust fund for a specific project. One such trust gives grants to community secondary schools for purchasing resources to teach about Christianity. Link to JT grants on the Stapleford website.
Biblical teaching encourages generous giving and the local school could be a worthy beneficiary. Some churches make annual gifts to their local school for resources related to teaching Christianity or to support Christian workers and activities in the school.
Churches can encourage members to collect the various supermarket school vouchers when they are available and donate them to the local schools. These have been the means of small schools getting much needed computer and sports equipment.
An annual gift day for education day could be established, possibly linked in with Education Sunday.
