PZ3 is a short numbered identity, and I would want to know what it represents before drawing conclusions about its educational role. The name itself gives a reader a reference point rather than a complete explanation. That is why context matters to me around [PZ3 education identity](https://pz3.edu.pl). I appreciate introductions that explain the audience and purpose in ordinary language. A visitor can then explore with a useful question instead of relying on an uncertain expansion of the initials.
