Which visa an Erasmus+ exchange actually needs, C or D
Whether you need the Schengen visa (type C) or the national visa (type D) depends on how long the program runs, not on the fact that it's Erasmus+. A short exchange, whether that's an intensive course, a summer school, or a few weeks of mobility under 90 days, falls under the Schengen visa (type C): Article 15 of the EU Visa Code, Regulation (EC) No 810/2009, sets a minimum EUR 30,000 for urgent medical treatment, emergency hospitalization, repatriation, and death. A full semester or academic year abroad, the more typical Erasmus+ format, needs the national visa (type D) instead. D visas sit outside the Schengen-harmonized rules, so their legal basis is Poland's own Act on Foreigners (Ustawa o cudzoziemcach) rather than the EU regulation, yet the two land on the same EUR 30,000 floor, a 24/7 assistance line, and validity for the whole length of the visa, up to a year.
This is the identical insurance requirement used for any other Polish study visa, work visa, or business trip: the visa itself has no separate "exchange program" category with different numbers attached. What actually sets Erasmus+ apart sits one layer above the visa, in the program's own insurance rules, which is where the confusion usually starts.
Which policy meets the Erasmus+ accident and civil liability requirement
Erasmus+ is an EU-funded program with its own insurance rules, independent of the visa requirements. The learning agreement and the grant rules call for a policy with at least EUR 30,000 of medical cover, plus accident insurance for your own injuries, plus civil liability insurance for harm to third parties. This part is usually checked not by the consulate but by your host university or the organization that runs the program. A standard visa policy does not guarantee all three elements, so the visa application and the program requirements call for different policies: any of the visa policies works for the visa, while the Erasmus+ requirements are met by the karta pobytu program from Kniazha, which includes both accident cover and civil liability. The other programs in the calculator do not meet them. You can buy it even when the student is already abroad, for example working over the holidays and not returning to Ukraine: in the calculator set "Your location" to "I'm abroad", then manually pick Kniazha from the list. The exact wording of the requirement depends on the university, so confirm it with the program coordinator.
If your situation doesn't fit neatly into Erasmus+
An exchange program is one specific branch of study-related travel to Poland, sitting alongside general enrollment, traineeships, and language courses. All of them share the same underlying visa insurance rules, even though the paperwork and program-specific extras differ. If you're not certain Erasmus+ is the right category for your trip, or you just want the fuller picture of what a Polish study visa requires before narrowing down to your specific program, our main study-visa insurance page covers that ground:

For the visa application, enter your destination, travel dates, and the purpose "Teaching" (that is how study is labeled in the calculator) to see live prices from the accredited insurers. For the Erasmus+ requirements (accident cover and civil liability), set "Your location" to "I'm abroad" and manually pick Kniazha from the list: that program fits, and the others do not meet these requirements. Before you hand the policy to your university or program organizer, check the accident and civil liability items in the certificate.
