ZSGiH looks like a school abbreviation, but its subject should be explained rather than inferred from the initials alone. I would want an introduction that identifies the learning context and makes the information useful to a first-time reader. That is how I approach ZSGiH school information. A concrete example can help someone understand what the name represents. I like educational descriptions that connect identity with practical questions, because an abbreviation is easier to use once its purpose is clear.
