NABSS´ schools base the pupils´ studies on the National Curriculum, employ fully qualified staff, and are expected to follow standard British practice in teaching and learning, leadership and management etc (see document of `Britishness´). Students and staff in NABSS´ schools  benefit from the multilingual and culturally diverse environment of British schools in Spain. Pupils are well prepared for life in an increasingly complex world.

NABSS´ schools offering the whole age range are required to run a broad selection of GCSE, AS and A level courses, or the International Baccalaureate, and to prepare students for university entry in Spain or the UK. The Spanish authorities give full recognition to A levels and grant direct access to Spanish universities for NABSS´ students with the appropriate A level passes.

An elected committee of Head teachers and owners of NABSS´ schools is responsible for the general management of the Association and its inspection service. Members are also kept up- to-date with all relevant legislation, both in Spain and the UK.

As NABSS is a membership organisation, all queries and requests for information should initially be directed to the individual member schools. The NABSS´ website lists all schools both alphabetically and by geographical area. Each school site contains full information regarding contact names, e-mail and site addresses and telephone numbers. Many schools can be contacted via a link to their own websites.
