Tighnabruaich Primary School is a non-denominational school for boys and girls from primary 1 to primary 7 (4.5 years to 12 years). The school also has Early Years provision, which provides education for children in their pre-school year and those in their ante-pre-school year (beginning the term following their third birthday) for five sessions of 6 hours each week during school terms.

The school is situated off the high road near the Royal Brae, as the village is approached from Dunoon. The older part of the building dates from 1874 but the school has recently been extended and upgraded to provide all necessary facilities under one roof, including a large gym hall / dining room. The newly refurbished building was officially opened in June 1998. A Portacabin was added in August 2022 to improve accommodation for our three class groups. At present the school has a working capacity for 74 children. Pupils transfer to Dunoon Grammar School to complete their secondary education.
