Bowlish Infant School in Shepton Mallet was evacuated earlier due to flooding.
Somerset County Council has issued the following statement:
All 113 pupils were led to nearby Bowlish House because of the threat of floodwater inundating the school.
The headteacher acted on the advice of Devon and Somerset Fire and Rescue Service which had been called to a neighbouring property.
The Council has also sent a structural engineer to inspect a wall there. It is holding back water from the River Sheppey which is threatening the school.
All the staff, parents and pupils have acted in a calm manner, and a decision will be taken later today on whether to close the school tomorrow.
It appears there is unlikely to be any let up in the relentless rain showers that have battered the West Country over the past few days.
Weather warnings remain in place today following heavy rain that devastated many areas in the South West over the weekend.
