Officials from Tusla, the Child and Family Agency, are due to appear before an Oireachtas committee next week to discuss revelations contained in an RTÉ Investigates programme on childcare facilities.
The programme 'RTÉ Investigates: Crèches, Behind Closed Doors' went undercover to look at standards of care at the Hyde & Seek chain of crèches in Dublin.
The Joint Oireachtas Committee on Children and Youth Affairs will question Tusla officials on Wednesday about what actions the agency is taking in response to the content of the programme.
In a statement, committee chairman Alan Farrell said: "Parents and guardians must be able to have confidence that their children are safe, secure and well-treated when in childcare facilities."
The Fine Gael TD added that "we need to know what Tusla as the regulator and inspector of early years services can do to close or suspend services when serious concerns are identified."
Separately Tusla has confirmed that the Garda Child Protection Unit at Mountjoy Garda Station has opened an investigation, along with the Tusla Social Work Unit, into the issues raised during the broadcast.
Hyde & Seek has said it will bring in external experts to review its management structure.

Meanwhile, dozens of people have attended a protest outside the Hyde & Seek crèche on Dublin's Tolka Road.
A number of signs were taped to the shutters of the crèche which was closed at the time of the gathering.
People who attended this afternoon's demonstration said they were appalled by the contents of the documentary.
They called for the crèche to be shut down or taken over by the Health Service Executive.
