British Schools Overseas Inspected

The BSO scheme is an initiative of the United Kingdom’s Department for Education (DfE). It is a voluntary inspection scheme for overseas schools that aims to help them make sure they provide their pupils with the skills and qualifications they need to enter or re-enter the British education system. The scheme helps to inform parents of how the standards in these schools measure up against the standards that apply to independent schools in Britain, insofar as this is compatible with the legal requirements of the host country.
