Polish Proficiency Test?

Hey everyone!
I'm not sure where exactly this should be posted but... I've been learning Polish since I was born; my parents both speak it as their first language. I am a junior in high school right now which means I will be applying to college soon. I was wondering if there are any Polish Proficiency Tests that I can take that will show that I definitely know the language? I want to include it on my college applications, however I feel if I just say "I know Polish" without any proof, it will be ignored.

I live in New Jersey, USA if that is important.
Thank you!

good luck:) and I've also heard about exams organized by Polish Embassy:)

I went to the Polish embassy last year to renew my Polish passport, I'm not sure if they do the exam and my mom said she doesn't know about it. I'll try looking into it more to see if they really do, though! Thanks. :)

Polish Supplementary School Council of America based in NY administers Regents exam of Polish as a foreign language approved by the Centre for East European Studies at Columbia University. RU is one of the places where you can take this exam. Their policy for the candidates is rather strict, you must be an American high school student and provide proof that you have been learning Polish language other than home environment for a substantial period of time or have completed at least primary education in Poland. Even if you do not qualify to take this exam I'm sure they would provide some kind of guidance. Good luck.

I have never taken any Polish school or classes, I know Polish simply by speaking it at home 24/7. I'm assuming, then, that I do not qualify for this exam.

Don't give up so easily. They conduct an oral interview with candidates, perhaps taking a course before the next exam which is usually held in October would qualify you provided your Polish is good enough, so why not giving them a call? See what they say. Perhaps they will suggest something that might suit your situation better, time is getting short for you. You have to knock on every door available to you if you want to achieve your goals.

Isn't that enough to write that it's your mother tongue? I don't think that they expect native speakers to prove their skills.

They then would require to prove that you know English :(

These are part of the official Council of Europe language testing process.
