According to the OsEAN membership standards from 2014 all existing members have to go through a mandatory audit until the end of 2017 in order to keep their status as a member. New applicants will be accepted only after completing an audit.
Please note that the audit process allows you to provide some documents later on, to complete the audit. Schools do NOT need to translate all documents in English, usually one of the auditors speaks the language of the school.
