The decline of the Gaeltachtaí and the failure of state-directed revitalisation have been countered by an urban revival movement. This is largely based on an independent community-based school system, known generally as Gaelscoileanna. These schools teach entirely through Irish and their number is growing, with over thirty such schools in Dublin alone. They are an important element in the creation of a network of urban Irish speakers (known as Gaeilgeoirí), who tend to be young, well-educated and middle-class. It is now likely that this group has acquired critical mass, a fact reflected in the expansion of Irish-language media. Irish language television has enjoyed particular success. It has been argued that they tend to be better educated than monolingual English speakers and enjoy higher social status. They represent the transition of Irish to a modern urban world, with an accompanying rise in prestige.
