Ev@lang has been developed by the CIEP's assessment and certifications department. The CIEP has more than 30 years' experience in the field of language assessment. The CIEP tests and awards diplomas in French as a foreign language – DELF (certificate in French language studies), DALF (advanced certificate of French language proficiency), TCF (French competency test), etc, - to more than half a million candidates across a network of 1,200 test centres in more than 170 countries.

Ev@lang is aligned with the proficiency levels defined by the Common European Framework of Reference for Languages. It has the added advantage of offering a total of 6 levels of proficiency and 6 subdivisions of these proficiency levels for greater accuracy.
