Sacred Heart Grammar School is a member of Newry & Mourne Area Learning Community. Collaborating with 16 other local schools and learning-providers, the Community strives to offer greater choice and flexibility for all post primary learners aged 14 and above. Sacred Heart has, in recent years, extended its curriculum provision at GCE AS and A Level by collaborating with Abbey Grammar School to offer students a broader curriculum so that they can choose a blend of courses which best suits their needs, aptitudes, aspirations and interests.
