it's designed for students, and as such, the lecturers aren't specifically trained in teaching Polish to foreigners.
that always seems to be the case.
i was looking into a polish school about 2 years ago but in the end decided against it. when i read the testimonials and other information on their website, as expected, it seemed as though every student at the school was a beginner and I simply didn't want to spend all that money so that I can sit in a class of 4 and say "to jest _____" and "Jestem_____" for 90 minutes a day, 3 days a week.
I've done countless hours of language exchange with Polish teachers. Not Polish people that teach English, but Polish teachers that teach Polish, and it was no different than sitting down with a random Pole off the street and having conversation. There is simply no demand for Polish as a Second Language here and the quality of teachers reflects it. I've worked for schools that started doing Polish lessons and you know how they choose their teachers? Like this:
"Hey Pawel, do you want to teach Polish next week?"
"Really? Oh man, I don't know if I can do it...geeze....."
"Ahhh, you'll be fine, I'll show you the book tomorrow, we'll go over it, no probs."
"Well, OK....I guess I'll see how it goes but......"
Or something to that effect.
Not to menion, Polish learning material is crap. I did Hurra Po Polsku 1 and 2 by myself without a teacher, Colloquial Polish, Isc czy Chodzic?, and they were all pretty lousy.
