Operational guidance to support the delivery of the 30 hours extended entitlement Early years entitlements: operational guidance - April 2017 - This builds on the statutory guidance and is intended to support local authorities and providers understand in more detail the Department of Education’s expectations about how the free entitlements should be delivered.
The Childcare Service System has also now gone live for parents with children up to the age of 4. This means that parents wishing to access the 30 hours free childcare entitlement from September, will now be able to apply using the system. Here is a link to the Online Childcare Service.
