Primary and secondary schools
The U.S. Embassy in Spain does not issue diplomatic certification of the validity of instruction performed by primary and secondary educational institutions, given that, in the United States’s federal system, there are no specific federal laws or regulations governing the recognition of accrediting agencies that accredit primary and secondary schools. As a result, the U.S. Embassy cannot comply with Real Decreto 806/1993. This has previously been communicated to the Spanish government.
In the United States, some states have laws requiring or encouraging accreditation for public schools and state-chartered private schools. Schools that possess state approval and, where it is required, accreditation recognized at the state level are generally considered to be recognized schools in the U.S. education system. States approve or license, and in some cases accredit, public and private schools operating within their jurisdictions.
The U.S. Department of State does maintain a list of education and international school associations, which may be useful to you as you search for guidance on how to pursue your interest in creating a school based on the U.S. education system.
Additionally, the U.S. Department of Education’s “State Contacts” website provides links to the websites of state-level departments of education, where information on school accreditation can be found.
