To anyone attending school who has travelled abroad:
Government policy, which is based on official public health advice, continues to advise against non-essential travel overseas for everyone.
It is a requirement for anyone coming into Ireland, from locations other than those with a rating of ‘normal precautions’ (“green”), to restrict their movements for 14 days, and this includes school staff, parents and children or other students coming from abroad to attend school in Ireland. Restricting your movements means staying indoors in one location and avoiding contact with other people and social situations as much as possible.
