DCEDIY have provided the following clarification with regard to the resumption of ECCE from 08 March, (Question 22 of the March FAQs).
Children eligible to return on 08 March
This is in addition to children considered vulnerable or children of essential workers who continue to be eligible to avail any service during this period.
Children not eligible to return until 29 March
For clarity, children who are ECCE eligible (based on age) and are availing of ECCE provision can also avail of non-ECCE hours during the same period. For example, if a child resumes on March 8th and requires full-time provision they can attend for the three hour ECCE provision and remain within the service for remainder of the day.
