Minister for Children Frances Fitzgerald has said she is concerned that so many crèche and pre-school staff had no garda vetting when they were last inspected by the HSE.
She was referring to evidence emerging from inspection reports published this week.
The second tranche of 37 reports from Limerick City and County was published this afternoon on the website pobal.maps.ie
According to the Department of Justice, at the end of last month, it was taking on average 12 to 14 weeks to process applications to the Garda Central Vetting Unit.
Ms Fitzgerald told RTÉ News that this marks almost a four-fold increase since earlier this year.
Minister for Justice Alan Shatter told the Dáil that one Garda Superintendent, three Garda Sergeants and approximately 136 civilian personnel were working for the unit in late June.
This civilian complement in the Thurles-based facility included 23 staff recently transferred from Department of Agriculture.
In addition, a further re-assigned 31 public servants were undergoing training, which will be completed for various cohorts between now and mid-September.
Mr Shatter said he expected this would lead to a reduction in vetting times.
