The annual CES Census is the source of all school data collected by the CES. No data on individual pupils is collected in the census. The name of the headteacher is collected, also a contact name and email address which are used solely for census communications the following year.

A document that describes the extent to which the CES census falls within the General Data Protection Regulation (GDPR) can be downloaded below. This document addresses questions that the CES has received from schools that raised concerns about the CES census and privacy of schools data.
