Although many private colleges have been closed down or found it no longer viable to continue, I suggest the damage is done.

Recently, I worked alongside a younger lecturer who claimed to have an MBA from Greenwich University but was unable to speak or write appropriate English. I suspect he gained his qualification from one of the private colleges who ran or still run Greenwich University business courses. In such places, the assessment tends to be weak and all kinds of people now have higher degrees.

The problem lies in teaching, as the students' of these individuals  pick up fractured English and consequently we will soon have a whole generation of individuals with Masters and above who possess the literacy of ten year olds.
