A former female staffer at an elite boarding school has been slapped with an 'extraordinarily lenient' suspended sentence after having sex with five male students during her tenure.

The 25-year-old, who worked at The Armidale School in New South Wales' north-east, has already spent 14-and-a-half months in prison on remand, following the offences during 2014 and 2015.

But on Monday NSW District Court acting judge Christopher Armitage gave the woman a two-year suspended sentence, in addition to being placed on the sex offenders register and a good behaviour bond.

Judge Armitage also noted the 'toxic culture' which manifested in the boarding house due to the school's choice to employ the young woman and the later ramifications this had.

The 25-year-old female staff member who had sex with five students at a prestigious boarding school took part with 'enthusiasm' and 'excitement' before being handed an 'extraordinarily lenient sentence

'The potential for trouble of precisely the kind that occurred was, I think, obvious,' he said.

The judge also acknowledged that although the penalty 'may seem like an extraordinary concession', the victims still had the court's 'extreme sympathy'.

'You have received an extraordinarily lenient sentence for what you did,' he told the woman.

The questioning of appropriate employment followed the defendant's mother's comments earlier in the day when she pointed blame at the elite school, claiming it has not taken 'correct responsibility'.

'My family's deepest and greatest regret is the trust we placed in The Armidale School where she was employed,' the mother said at the sentencing hearing.

The woman pleaded guilty to six counts of sexual intercourse with a person under her care and three counts of aggravated sexual intercourse, in April.

The incidents occurred with students aged between 15 and 17 over several months in 2014 and 2015, at her staff accommodation room. The woman was 20 when the offences began.

Her mother told the court she made some appalling errors of judgement but is 'an outstanding person.'

Judge Armitage asked the mother why a fine person would commit such a crime.

She responded: 'It is my opinion, knowing my daughter, that the school has not taken correct responsibility.'

Her daughter had experienced significant emotional trauma in her life, including her close friend committing suicide.

The woman had undergone counselling when she was younger as she was 'emotionally unstable' at 15 and put on a substantial amount of weight, to about 125kg.

'She struggled with relationships with the opposite sex. She would tend to be drawn to people who would manipulate her,' her mother said.

Last week the former staff member told the court she was treated like dirt and claimed the boys threatened to report her if she didn't continue to have sex with them.

'At the time I was going along with what I thought was going to keep them happy,' she said before Judge Armitage on Friday.

She also alleged one of the teenagers raped her on two separate occasions.

The woman said she was remorseful for her actions and the situation - which got out of hand - was not dealt with correctly.

The court heard that thousands of text messages were exchanged between the students and some were read out.

One boy texted his friend: 'you rooting that fat s*** tonight?'

In a text sent to the woman, a male student said he and his friend wanted to put her 'on the spit'.

The woman had messaged the students about fears she could lose her job and go to jail.

The students texted about what would likely happen when the behaviour became known.

'I'm saying I got raped,' a student texted. 'Yeah, f*** the c***, we'll all say it,' replied the other.

The court heard that the woman had texted a boy, 'I can't wait to cuddle you tonight'.

Judge Armitage told the court the text messages suggest 'enthusiastic participation' from the former staffer.

He also said the woman was suffering psychological distress in prison as inmates referred to her as a 'kiddie fiddler.'

Judge Armitage lifted suppression orders prohibiting the name, location and type of the school after parents of the boys wrote to the court, claiming the school needed to be held accountable.

In sentencing, the magistrate acknowledged the woman's sanction came with additional conditions including the continuation of psychological treatment.

The suppression order on the identity of the staff member remained.
