https://spsw.edu.pl SPSW looks like an abbreviated school name, but I would not expand it without a clear explanation. I am interested in how a visitor understands the educational setting and finds the information relevant to their question. That is my starting point for SPSW school information. An introduction should make the audience and purpose visible, especially for someone outside the existing community. I like practical examples that give the name context instead of relying on the initials to explain the whole identity.
