Hi Damian: Usually, any native speaker will be able to tell you your basic proficiency level, whether it is basic, intermediate, or advanced. However, if you want a more exact evaluation (A1,A2,B1,B2,C1,C2) you would probably need to ask someone who has significant experience teaching. This assumes you want to know for your own benefit and to not need an official test to document your ability. Good luck!

I agree with Samuel. Are you speaking with any native English speakers? They should give you a good sense of how well you are using spoken English.
