Generally in the UK, IT teachers are hired primarily for the ability to act as a sysadmin and tech support (for the whole school) - and are frequently called away to fix the principal's printer, as a facetious example. The content of high school computer science courses is significantly influenced by this: the preference is for admin-heavy or Microsoft-heavy courses, which can be easily covered by non-specialist staff, and traditionally feature zero programming skills. This is changing, but in my opinion teaching in computer science field is still impeded by teachers needing to be sysadmins first.
