Who owns the equipment is not relevant. What matters is that the photography complies with management policy and permissions. There are privacy considerations as a classroom or learning situation is one where it can be argued that a normal expectation of privacy applies. This means you must have permission of the learners. If the learners are minors, parental or guardian permissions will be necessary, and also supervision by CRB checked staff. Consult the principal for guidance. If you intend the photographs to be used for publicity, marketing or advertising, you should obtain model releases (see elsewhere in this FAQ).
