A category which is used to identify members of staff other than those classified as academic. If a member of staff is not one of the three types specified for the academic classification, they are to be classed as having a non-academic classification. This convention applies even if the member of staff has a salary which is related to or tied to those of academic staff (which may occur, for instance, for registrars and librarians). If a member of staff is classified as being non-academic then the member of staff cannot be coded as having a teaching-only or teaching-and-research function. As occupation-based classification groups no longer apply to non-academic staff, such staff should be reported simply as non academic (code 11) for Element 409.
