The report followed a monitoring visit to Aontacht Family Services, which provides housing placements to families under assessment.
Parents are required to stay and are assessed on whether they have the ‘necessary skills’ to look after their children.
The inspection focused on the safeguarding of a 14-year-old mother at the centre.
It stated the placement should not have been accepted, as the child was ‘looked-after’, meaning she was under the care system.
Grace O’Reilly, managing director at Aontacht, claimed this was not the case when the girl was admitted.
She said the home told Ofsted when registering that it would accept parents as young as 14.
However, Ofsted said the home isn’t registered to care for looked-after children and labelled the placement as a ‘significant incident’.
When asked about the report, Ofsted said it does not comment on individual settings.
The report said safeguarding incidents at Aontacht are rare, and when they occur, staff respond ‘effectively and appropriately’, informing relevant professionals in a ‘timely’ manner.
It said staff work closely with parents and help them understand risks and how to manage them, and that they have access to courses to build their parenting skills.
Ofsted also praised the centre’s ‘comprehensive’ risk assessments.
Ms O’Reilly said: “We strongly dispute the recent report published by Ofsted, which contains factual inaccuracies and presents an unduly critical view that lacks appropriate context.
“We have consistently operated within the framework of relevant regulations, and as such, we were deeply disappointed by Ofsted’s approach as our regulator.
“Accordingly, we submitted a formal complaint regarding their handling of this matter.
“While we are disheartened by the experience, we hope that the learnings from this case contribute to the development of improved policies and procedures.
“It is vital that no other Ofsted-regulated setting is subject to the poor service we have received, and more importantly, that services for young parents who are also looked-after children are reviewed, ensuring they are afforded a fair opportunity to remain with their babies.
“Despite this matter, Aontacht continues to hold an overall Ofsted rating of ‘good’, with no concerns raised regarding the quality of service we provide.
“We remain proud of our work, the positive reputation we have built, and our ongoing commitment to supporting families with integrity and professionalism.”
She explained that it is rare for a foster carer to be licensed to care for both babies and teenagers, meaning young parents and their children are often separated.
Ofsted published a blog on September 3, after the report, which clarified looked-after children shouldn’t be placed in family centres.
The blog also said: “The current regulations and national minimum standards that underpin Ofsted’s regulatory and inspection work are out of date and need urgent revision.
“This limits our ability to regulate services well.”
