I was editing my profile on lernu! just now, and I came to the part that asks for your Esperanto level. The options were:
none basic (A1-A2) intermediate (B1-B2) high (C1-C2)
I recently ran into someone who was talking about how her son had taken a test for Esperanto, and gotten the highest score possible, which was, she said, C-[number]. I can't remember exactly, only that she said the letter c, then a number, and I thought, 'Hmm, that's an interesting way to measure a test score. I didn't know such a test existed, either.' Now I guess she said C-2… but I'm still in the dark about the test.
When I first made my account on the older version of lernu!, I had put 'basic' as my answer. I don't remember there being the letter-number level equivalent beside (although maybe there was and I've just forgotten), so I just picked the one that sounded right to me at the time. But now, I'm wondering about these levels. So is there a test you're supposed to take to officially achieve, say, a B-1? Am I supposed to have taken it? Where would I find it?
I don't want to guesstimate like last time. It wouldn't be the end of the world if I did, but I do like things to be precise… :-)
This is what that person was referring to, the Common European Framework of Reference for Languages: http://www.coe.int/t/dg4/linguistic/Cadre1_en.asp
Even though Esperanto is not an official language in the European Union, a series of tests that fit within the CEFR model has been developed under the name Komuna Eŭropa Referencekadro (KER):
Exams for Esperanto are currently only available for levels B1, B2, and C1.
