“In accordance with normal procedures, letters have been sent to the parents concerned informing them of what to do.
“Pengelli Primary School is a small school with around 120 students and staff.
“As a small school it was agreed that the most appropriate way to support staff and students is for the school to remain closed until later next week.
“In the meantime, children will learn through blended learning.”
