Differences between working in Secondary and Primary?

[Iwillhavethefullenglishplease]

I have a fair amount of experience in working in Primary school admin but have an opportunity to work in Secondary.
What are the main differences in the what would be expected of an admin in each type of school (assuming both the same pay grade).
In an interview situation, what sort of questions are they likely to ask? Would it be the standard type of admin in school question, or is it likely to be different in a secondary school?

I have worked in both primary and secondary offices. Interview wise, the questions were pretty much the same.

Work wise, it depends if you're front office or back office admin. The back office ones work in specific departments, eg pastoral or attendance admin. Their workload is a bit different.

Secondary school front office admin I have found to be fairly similar to primary school. You might do a bit of everything from answering phones to organising trips to dealing with students. Some schools assign admins to assistant heads to also provide support to them.

Generally, secondaries are larger than primaries and everything is done on a bigger scale.
