Sgoil Ghàidhlig an Àrd-Bhaile (The Gaelic Language Society of Halifax) promotes, provides and supports community-based, authentic Nova Scotia Gaelic language learning, within a cultural context, for people of all ages in the Halifax Regional Municipality. Sgoil Ghàidhlig’s language immersion courses utilize a methodology known as "Total Immersion Plus" (TIP), which was introduced to Nova Scotia by Finlay MacLeod of Comhairle nan Sgoiltan Àraich, the Scottish Gaelic Preschools Association. Immersion courses of this type are also known as Gàidhlig aig Baile or "Gaelic in the Community".
