This  requirement is explained in more detail  here<https://www.gov.uk/government/news/national-database-of-governors>

The Department for Education (DfE) has recently informed us that a significant number of local authority  maintained schools have yet to complete their governance fields on  Edubase.  Governors hold an important public  office and this new measure is a helpful way to increase transparency on  those who govern our schools.  While child protection and safeguarding  investigations are rare, having this information in one place will make  it quicker and easier to more accurately identify where someone is  involved in the governance of schools.

Can we remind schools of  their duty to complete all the fields on Edubase in respect of each governor; all information will be encrypted and held securely so governors should not feel any  concern about providing the data.
