The national broadcaster RTÉ will be the subject of an impartial "root and branch examination," according to the Irish government.
The statement was made by Irish Minister of the Media Catherine Martin, who claimed that the organization's reputation "has been shattered.".
The test will consist of two independent, parallel reviews.
The broadcaster's culture and governance will be the primary topics of the first strand.
Contractor fees, human resources, and other issues, such as gender equality and inclusion, will be reviewed again.
The announcement is made in the midst of an ongoing controversy surrounding sizeable undeclared payments made to former presenter Ryan Tubridy.
The trust of the public, according to media minister Catherine Martin, "has been shattered.".
In a statement on Tuesday, Minister Martin said: "RTÉ has offered a public forum for Irish citizens to converse with and about one another ever since the first broadcast of its predecessor Raidió Éireann.
"At its best, it has held up a mirror to Irish society, one that has shown both the best aspects of our society and one that has also revealed its injustices, both obvious and occasionally all too hidden.
"In doing so, RTÉ has been supported by the people's trust as well as the tireless efforts of its staff over the years.
"That faith has been destroyed. The beginning of our efforts to rebuild that trust is the independent, root and branch investigation of RTÉ that I am announcing today. ".
Last month, it came to light that Ryan Tubridy received €345,000 (£296,800) more than had been publicly disclosed.
The presenter expressed regret for not questioning payments made to him but insisted that all of his taxes were "up to date" and that his earnings had been accurately recorded in his company's accounts.
On June 24, Minister Martin commanded an outside review of RTÉ's management and culture.
On June 26, Dee Forbes, the previous director general of RTÉ, submitted her letter of resignation.
According to interim director general Adrian Lynch, only Dee Forbes could have known the published pay figures for Ryan Tubridy were incorrect among the executive board members of the broadcaster.
The head of RTÉ and other executives have testified before the media committee of the Oireachtas (Irish parliament) to discuss the payments.
The broadcaster's employees have protested the pay scandal.
Last week, RTÉ employees participated in a protest at the broadcaster's Dublin headquarters.
The government has mandated that management disclose all details regarding payments made to Mr. Tubridy because RTÉ is funded by a licence fee.
The government's examination is anticipated to take six months.
An expert advisory committee, consisting of Prof. Niamh Brennan, Dr. Margaret Cullen, and a third member to be named soon, will be in charge of monitoring the governance review.
Brendan McGinty, Patricia King, and a third member will serve as the chairpersons of the second review committee.
A team from the Department of Tourism, Culture, Arts, Gaeltacht, Sport, and Media will support both committees as they work concurrently and when necessary, coordinate.
RTÉ's governance, culture, and practices will be scrutinized in an unprecedented way, according to a government spokesperson, who made the announcement today.
"These steps are required to make public service broadcasting open, transparent, and answerable to the people.
