DIALANG is an online diagnostic system designed to assess a person's proficiency in 14 European languages.[1][2] Competences tested are reading, writing, listening, grammar and vocabulary, while speaking is excluded for technical reasons.[1]
DIALANG was designed primarily for European citizens to assess their language abilities in adherence to Europe’s Common European Framework of Reference – CEFR – as a basis for determining language proficiency. The CEFR is a widely recognized framework used to describe and measure the language proficiency level of a learner in a particular language.[1]
Dialang was funded by the SOCRATES programme and by some 25 institutions, largely universities, throughout the European Union.[3] Dialang is explained in the Appendix C, pages 226-243 of the CEFR official document.
