A review of TDs' attendances in Leinster House is to take place following a number of controversies in recent weeks.
The review will examine the "fobbing in" system which records politicians' attendance in the Dáil so they can claim expenses.
The Houses of the Oireachtas Commission, which oversees the delivery of services at Leinster House, made the decision at a meeting today.
It follow controversy surrounding attendance records after several TDs were marked as present but were absent for votes.
The review will include the views and input of each political party, as well as the Minister for Public Expenditure and Reform Paschal Donohoe.
It will also have a presentation from the Audit Committee to the Commission and an examination of best practice internationally.
The review is due to be completed by January and any recommendations made will be forwarded to Minister Donohoe.
Speaking after the meeting, the Ceann Comhairle Seán Ó Fearghaíl said it was "vital" that credibility and public confidence are restored in the system and the administration of allowances to TDs.
Today's meeting came after Catherine Murphy of the Social Democrats sent a letter to the Ceann Comhairle asking him to overhaul the system.
Under the current rules, TDs must attend the Dáil at least 120 days in the year to claim a Travel and Accommodation Allowance.
This amounts to around €2.9m a year in total.
