ASL is accredited by the Department for Education (DfE) and The Middle States Association (MSA). ASL has been accredited by MSA for several decades and by the Department for Education (DfE) since 2006. ASL is a member of the National Association of Independent Schools, the Council of International Schools, the Independent Schools Association (ISA), and the Association for the Advancement of International Education (AAIE)

The DfE approves inspections from two inspectorates: either Ofsted or the Independent Schools Inspectorate (ISI). Both inspectorates use the same standards for independent school assessment. As ASL met all expectations during our progress monitoring inspection from Ofsted in October 2022, our Board of Trustees unanimously recommended that we transition to the ISI in the course of the 2023-24 school year. ISI has a specialized focus on and expertise in independent schools, making the rigorous inspection process and report more meaningful and valuable for our school.
