The accreditations were first awarded to Colegio Gran Bretaña in 2004. Ten years later CGB has been re-accredited. This demonstrates its commitment to international education and continual improvement. Colleges and universities acknowledge that an Accredited School meets globally recognised standards and promotes qualities and skills that they are seeking in students.

CIS School Evaluation and Accreditation is an evaluation process that drives a school’s continuous improvement, through:

  • rigorous evaluation against internationally-agreed standards;
  • a blend of support and challenge, focused on a school’s development; and
  • a peer-based model that brings together international educators from across the world of CIS-accredited schools.

Our Second Accreditation with the New England Association of Schools and Collages (NEASC) ensures compliance with United States standards and thus facilitates the transfer or US students back to their home country, as well as the admissions process into US Universities.
