Home School Hub

The hour-long main show, broadcast Monday-Friday at 11am, typically consisted of three lessons, one from each of the main presenters, (qualified teachers Múinteoirs[lower-alpha 1] Clíona, Ray and John).[7] As is standard for primary school education in Ireland, the teachers gave their lessons bilingually through English and Irish.[8] In place of commercial breaks, the programme has smaller inserts from RTÉ-produced/commissioned educational programmes such as The Body Brothers, I'm an Animal, Pink Kong Studios' Urban Tails and Colm Tobin's Brain Freeze.[9] Comic book artist Will Sliney also presents short drawing lessons in the "We Will Draw" segment.[10]

A 15-minute-long compilation of material submitted by viewers relating to the content of recent shows, Home School Extra, narrated by Múinteoir Ray, was shown after the main show, and repeated at 4.15pm.[8]

Irish Sign Language signed version of a previous main show has broadcast at 1pm from April to July.[11][12]
