All accrediting bodies would need to do would be to ask for the course content details and see to what extent ethics form an important component of the various modules that are being taught.
In our first year course, the first three lectures that first year students have are all about ethics and regulation. It is an integral part of the introduction to journalism. But there is no ethics module. It is like a stick of rock, it goes through virtually every one of the modules that is being taught at the discretion of the individual lecturer. But it would be quite easy to actually accredit on that basis by seeing to what extent those components are contained within existing courses.
