Currently, refugees are allowed to study with qualified educational certificates and sufficient knowledge of German in Lower Saxony. Persons who have no proof of a higher education entrance qualification, either because they lack the appropriate educational background or cannot verify the necessary documents, may acquire the necessary entrance qualification for a chosen study subject depending on the individual prerequisites, for example with an entrance test or an aptitude test at the "Niedersächsisches Studienkolleg". An aptitude test is required for admission, especially when formal qualifications are missing or are insufficient.
