There are various stages to the competition. In Ireland there are county and provincial competitions leading to the All-Ireland Fleadh. In Britain there are regional, then national stages of qualification for the All-Ireland. North America has two regional qualifying Fleadh Cheoil. The Mid Atlantic Fleadh covers the US eastern seaboard, eastern Canada and the Maritimes. The Midwest Fleadh covers the rest of North America from Cleveland, Chicago, St. Louis, Atlanta and Detroit to San Francisco.
Competitions are divided into the following age categories: under 12, 12–15, 15–18, and over 18 (senior).
The first national festival of Irish traditional music was held in Mullingar in 1951. At its inaugural meeting in September 1951, CCÉ came up with the title of Fleadh Cheoil, aiming to make this a great national festival of traditional music. The fleadh has been held in many different venues.
In the years that followed, the number of would-be competitors grew so large that qualifying stages had to be arranged at county and provincial levels. Since then, Fleadh Nua (the new fleadh), Fleadh na Breataine (an All-Britain fleadh) and regional fleadhanna in Britain, and two major fleadhanna in the USA have also become annual CCÉ events.
From its beginning, the goal of the Fleadh Cheoil was to establish standards in Irish traditional music through competition. The fleadh developed as a mainly competitive event, but it also included many concerts, céilíthe, parades, and sessions.
Today, nearly 50 years on, fleadhanna at each level provide a platform and a meeting place for the thousands of musicians, singers and dancers who carry on the tradition. Around 20,000 performers compete in fleadhanna each year.
The 2008 festival was held in Tullamore, County Offaly and attracted an estimated crowd of 250,000 people making it Ireland's largest festival, music or otherwise. The Fleadh is scheduled to go to Sligo in 2014.
According to CCÉ's official rules for 2005:
- Solo competitions shall be held for the following instruments: fiddle; two-row accordion; concert flute; whistle; piano accordion; concertina; uilleann pipes; harp; mouth organ; banjo; mandolin – excluding banjo-mandolin; piano; old-style melodeon; bodhrán; war pipes; miscellaneous such as three and five row button accordion, piccolo, [chromatic] harmonica and other stringed instruments; céilí band drums; accompaniment – confined to piano, harp, guitar and bouzouki-type instruments; solo traditional singing in Irish and English; whistling; lilting; newly composed ballads and amhráin nua-cheaptha (newly composed songs in Irish).

There are also competitions for the following ensembles: duet, trio, céilí band, instrumental group (grupaí cheoil), accordion band, pipe band, and miscellaneous ensemble.
Towns and cities wishing to host Fleadh Cheoil na hÉireann must submit several applications to Ardchomhairle an Chomaltais – the highest committee within CCÉ. Certain members of the Ardchomhairle then inspect the applicant towns and the locations that have been proposed as competition venues, before coming to a final decision several weeks after the preceding fleadh, usually in September. Once a town has been chosen to host the Fleadh, it undertakes to host the festival for two consecutive years. However, Comhaltas has the right to deny any the successful town the Fleadh for the second year if poor venues, organisational problems, etc. are demonstrated on the town's first year of hosting. On 10 September 2011, the 2012 All-Ireland Fleadh Cheoil was awarded to Cavan, County Cavan, for the third year in succession. The other towns who applied for the 2012 festival were Ennis, County Clare; and Sligo, County Sligo. The Fleadh was held in Derry in 2013, the first time that it was held in Northern Ireland. One of the primary reasons for holding the Fleadh in Derry was due to that city being awarded the UK City of Culture for 2013. In 2014, it was confirmed that the Fleadh Cheoil would be held in Sligo for 2014 and 2015.
