To assess your level I use the Common European Framework of Reference for Languages (CEFR) as it is the language level chart officially used in the European community.
To be assessed, contact me.
The Common European Framework of Reference for Languages (CEFR)

The CEFR describes what a learner is supposed to be able to do in reading, listening, speaking and writing at each level.
These descriptors can apply to any of the languages spoken in Europe.
