The Government will ensure that the electronic common assessment framework (eCAF) system is secure and that it will comply with stringent Government and international protective security standards. Access to it will be restricted to authorised users, who need to use it as part of their job. There are two types of authorised user: practitioners, who use eCAF to perform their professional roles relating to children; and system administrators, who perform IT-related tasks on the eCAF system itself, or on the data held by eCAF. Both types of user must pass CRB checks and will also be subject to the Vetting and Barring Scheme (VBS).
