A mother has pleaded guilty to behaving in a threatening or abusive manner at Tweedbank Primary School.
Angered by a school exclusion order, Caroline McLaren, 40, ripped up the paperwork and stormed out of an office, Selkirk Sheriff Court heard on Monday.
The offence happened as pupils aged between five and 10 years old, were preparing to leave at the end of the day.
McLaren, of Weavers Linn, Galashiels, pleaded guilty to the offence, which took place on January 24.
Prosecutor Tessa Bradley said the head teacher was made aware of a pupil “misbehaving and disrupting the class”.
She added: “A decision was made to have him excluded from the school and unsuccessful attempts were made to contact his parents.”
When McLaren arrived at the school to collect her child, she was met by the head teacher and informed of the problem.
The prosecutor went on: “She lost her temper and shouted at the teacher, and when she was handed the paperwork she ripped it up.
“She stormed out of the office into the open-plan area which was full of children, and continued shouting. She was asked to calm down.
“Some of the children were visibly frightened and upset, and at least two were in tears.”
Ms Bradley said the school received a number of calls from parents whose children has returned home upset.
Iain Burke, defending, said his client was unaware of any pupil crying and was “extremely apologetic for any upset caused”.
The solicitor added: “There is a history with the school and her children no longer attend there.
“She went to pick up her child as usual and was brought into the office. She asked for an in-school exclusion, which was refused, and things escalated and she began to raise her voice, tore up the letter and went outside in a state of agitation.”
Mr Burke said McLaren had contacted the local authority and her MSP to try to resolve matters, and her children now attended a new school where they had gained certificates for good behaviour.
He added: “She acknowledges her behaviour was unacceptable, but there must be some credence to what she says, given their improved behaviour.”
Sheriff Kevin Drummond told McLaren: “Your behaviour was totally and absolutely unacceptable, particularly in sight of a number of children, and is no kind of example to be giving to your own children or any others.”
Sentence was deferred until September 23 for reports.
