Glasgow councillors will decide whether to press ahead with proposals to close or merge 13 primary schools and 12 nurseries across the city later.
Extra security measures will be laid on ahead of the council vote on the plans, which have met fierce opposition.
Parents and local people have staged a series of protests, including sit-ins, marches and a roof-top demonstration.
The council has carried out a public consultation on the measures, which it says are necessary to save money.
The authority said the closure plan was drawn up after a “city-wide assessment.”
The proposals have provoked widespread anger from some parents and community groups who believe they will have a negative impact on pupils’ education.
Earlier this month more than a dozen people staged a sit-in at Wyndford Primary and St Gregory’s Primary in Maryhill which lasted almost two weeks.
Pupils at Our Lady of the Assumption Primary in Maryhill were sent home on 20 April after four parents staged a demonstration on the roof of the school
It came as protestors occupied Victoria Primary in the city’s south side, with some chaining themselves to railings.
Marches have taken place against the closures, and protestors have regularly gathered outside council offices to voice their concerns.
Councillors will vote on each of the 25 proposals in turn at the meeting of the full council at Glasgow City Chambers.
A council spokeswoman said all 30 tickets for the public gallery had already been allocated.

PRESS RELEASE … for immediate use (22nd April)
24 HOUR VIGIL AND BLOCKADE OF GLASGOW CITY CHAMBERS
As decision-day at the Glasgow city council looms, parents and carers in the Glasgow Save Our School Campaign have decided to hold a 24-hour vigil outside the City Chambers from 12 midday today (Weds), in the run-up to the Mass Blockade of the meeting at 12noon on Thursday.
Glasgow Save Our Schools Campaign organiser, Richie Venton, today said:
“People who care for their kids and communities are full of fear for the future, fury at Labour councillors who threaten the closures, and firm determination to fight on
“The peaceful vigil will have a stark message to Steven Purcell and his team of councillors: we are watching you!
“Watching whether Purcell has the decency to meet parents and try to justify the indefensible closures, after going into hiding for weeks.
“Watching whether at least 7 Labour councillors have the principles and strength of character to rebel against the closures of all the schools and nurseries, and help stop larger classes, in old buildings, with less staff being the fate of our kids.
“The vigil will help spread the message to the public that when the Council meets to vote on Thursday, they should encounter a mass human blockade demanding they save our schools or face the sack, that they should put kids before cash.”
