Update 11.45am: Some schoolchildren will be forced to stay at home on Tuesday next week as teachers go on strike in a dispute over pensions.
The country’s two biggest teaching unions, the National Union of Teachers and the National Association of Schoolmasters Union of Women Teachers, have called the strike.
They are fighting against Government plans to dismantle their national pay system, extend the school day and increase their pension age.
Casterton Business and Enterprise College will be closed to all pupils.
Principal Victoria Crosher said the college was closing because the majority of the teaching staff were intending to strike making it impossible to supervise and guarantee health and safety of pupills during the day.
Rutland County College, at Barleythorpe, will be open as normal.
Bourne Academy will only be open for pupils in Year 7, Year 11, Year 12 and Year 13.
Headteacher Lawrence Reilly said the decision to partially close the school has been made on health and safety grounds, taking into account the number of staff who will be taking part in the action.
The school is remaining open to older with exams later this academic year to minimise disruption.
He said the Bourne Academy was admitting Year 7 pupils to ensure that they had continuity at their new school and to allow as many parents as possible to operate normally.
Stamford Queen Eleanor School will also only be open to Year 11 pupils due to the number of staff who will be joining the strike.
The Deepings School will only be open for pupils in Years 11, 12 and 13.
Headteacher Chris Beckett said: “We have taken the decision now to give parents as much warning as possible.
“I have 80 members of staff who are union members and at this stage I know half of those are taking part in the action.”
At the moment Bourne Grammar School expects to open for pupils in Years 7 to 12 but Year 13 pupils have been asked to study at home.
Stamford Endowed Schools, Catmose College in Oakham and Uppingham Community College will be unaffected by the strike but Casterton Business and Enterprise College was not expected to make a decision until today.
Malcolm Sargent Primary School in Stamford will be affected with only five of its 19 classes being open to pupils on Tuesday.
St George’s Primary School will also be partially affected.
Uppingham CE Primary School will also be affected. Headteacher Iain Peden refused to say what the situation will be but said parents have been informed.
All other primary schools in Stamford, Bourne, The Deepings, Oakham and Uppingham are expected to remain open at the moment, but teachers do not have to inform their employers of their intention to strike until the morning of the action.
Lincolnshire County Council will list any further school closures on its website
