LIS is an International Baccalaureate (IB) World School and is authorized to offer three International Baccalaureate programmes: Primary Years Programme (PYP), Middle Years Programme (MYP) and the IB Diploma Programme (DP). We use these programmes as the framework for an inquiry-based approach to learning and teaching.

LIS is also fully accredited with the New England Association of Schools and Colleges (NEASC) and the Council of International Schools (CIS). LIS is a member of the Association of International Schools in Africa (AISA) and the WIDA International School Consortium.
