You make an interesting point here. In FE you could become a Lecturer with an HNC/D or an FTC after completing a one year Cert ed. That was back in late 70's very early 80's then they changed the entry qualification to degree plus cert ed, through the 80's into the 90's, that was other than, for those already in service Lecturers who were funded to take the required qualifications. I have always thought that you need at least one level above the qualification you wish to teach. Then of course there is the touchy subject of the lowering of degree standards.
