After a bit of research on the Internet (god I love wikipedia) it turns out that there is a Common European Framework of Reference for Languages and an Association of Language Testers in Europe (ALTE). After digging a bit further it turns out that the prestigious Jagiellonian University in Krakow is the Polish ALTE member responsible for the Polish language exam for foreigners as commissioned by no less than the Polish Ministry of National Education and Sports.
Here is the official website (from what I can work out anyway) on the Polish as a Foreign Language series of exams. There are currently 3 exams:
- Basic level - Poziom podstawowy - ALTE level B1
- Medium level - Poziom sredni ogólny - ALTE level B2
- Advanced level - Poziom zaawansowany - ALTE level C2
If anyone has done these exams or can recommend preparatory materials, please let me know!
