Je trouve ce terme en tête d'un document officiel (évaluation de la situation d'une famille et des enfants) et je ne comprend pas ce que cela veut dire. Il n'y a rien d'autre sauf :
Quelqu'un aurait une idée?
The use of quotation marks (inverted commas) does not necessarily indicate irony. They are often used when a word or expression is introduced in case it is new to the reader, then not used in subsequent mentions. However, that was just a guess. As you point out, it's hard to know the meaning when there is so little context.
As another wild guess, maybe it refers to something like this: In computing, the superuser is a special user account used for system administration. Superuser - Wikipedia
If I understand correctly, ordinary accounts allow people to get information within certain limits; superuser accounts allow access to everything.
Superuser can be spell either the way I just did or as two words linked with a hyphen, super-user. I've also noticed the current ( as well as nasty, imho) tendency to drop those helpful punctuation marks.
