Welcome to Sligo Grammar School
It is my privilege as Headmaster to write this introduction for our school website.
The keystones to Sligo Grammar Schools success include respect, trust, co-operation, participation, consultation, collaboration and teamwork. Our enthusiastic and dedicated staff place great emphasis on a holistic education. Such efforts are channeled so that our pupils develop the characteristics of good reliable citizens, fit to take their place in society. Together with a fine tradition of sport and community involvement, the school offers a wide range of activities to ensure the personal and social development of the whole child.
Our Mission Statement below explains more formally what we aspire to achieve…
