[6] In 2014, as part of a reorganisation of how funding was allocated through Foras na Gaeilge (FnaG), Gaelscoileanna Teo was appointed as one of the six "lead" Foras na Gaeilge-funded Irish language organisations- with a responsibility for the support of Irish-language medium education at preschool (outside the Gaeltacht) and primary and second-levels in the Republic of Ireland.

[1] As part of this reorganisation, for example, Forbairt Naíonraí Teoranta (a voluntary organisation that worked with Irish-medium pre-schools) was merged into Gaelscoileanna Teo.

[9] FNT provided support in establishing and running naíonraí (pre-schools), naíolanna (crèches), parent/guardian and toddler groups, after-school services and summer camps.
