Former senator Jillian Van Turnhout has been appointed to examine the adequacy of governance arrangements at Scouting Ireland.
Minister for Children and Youth Affairs Katherine Zappone made the announcement in the Dáil.
She said that Ms Van Turnhout will provide her "with a clear assessment of the adequacy of Scouting Ireland's governance arrangements and to advise me as to whether I can be assured of scouting Ireland's governance and related matters".
The appointment follows a controversy over Scouting Ireland's handling of a rape allegation against an adult volunteer.
Ms Zappone announced last month that she would be withholding funding from the organisation following the controversy.
Following the controversy, the organisation's Chief Scout Christy McCann temporarily stepped aside from his role pending the completion of an investigation.
Three other members of the National Management Committee have also stepped aside temporarily.
