Crosshouse Primary School will not reopen to pupils at the start of the school term.
The village primary school is currently undergoing a £6.8 million refurbishment and extension but delays have scuppered plans to reopen at the start of the new term in a few weeks.
East Ayrshire Council bosses wrote to parents recently to let them know that the school would not reopen on August 18, conceding that the situation was "not ideal" and will cause further "uncertainty and disruption".
