Tusla is insisting it will never force a child abuse survivor to be interviewed by their alleged abuser.
It is introducing new guidelines from June for dealing with adults making disclosures about childhood abuse.
The new measures could mean people accused of child abuse could cross-examine their alleged victims.
Groups working with survivors say they are worried the measures favour the alleged abuser.
Maeve Lewis, Executive Director of One in Four, said it is crucial adult survivors are protected.
Ms Lewis said: "The reality is most children don't tell when sexual abuse is happening, they may disclose when they feel safe, when they are adults and when they are out of that situation.
"So, it's really important that we create an environment where the testimony of adult survivors is freely given. That testimony can help us understand that the person that abused them may now be abusing younger child, another child."
