Parents, teachers and students await news about whether classes will return for the remainder of the term as the Education Minister is set to announce the next steps for schools.
In England, children in nursery, reception, year 1 and year 6, alongside priority groups, returned to the classrooms in as part of a wider easing of lockdown measures in England.
However a decision is yet to be made in Wales where schools have been closed since the outbreak of coronavirus in March.
Both the Education Minister and the First Minister Mark Drakeford have said that schools would definitely not open to all children before July at the earliest.
In Wales, as across the UK, some schools have been open throughout the lockdown for the children of key workers.
However, earlier this month, Mark Drakeford told Good Morning Britain he would like to see Year 6 pupils and children facing exams next year back at school before the summer holidays.
The Welsh Government published a 20-page document outlining its plans to lift Wales out of lockdown.
In what has been described as a "cautious approach" which puts the "health of the public first", the traffic light-style system details how different sectors of society would be able to return.
Under the amber traffic light, priority groups of pupils will be able to return to school in a "phased approach" with increased numbers of children in childcare.
Under the green traffic light, all children and students will be able to access education and childcare.
Any changes will be announced during the Welsh Government's daily briefing on Wednesday.
