My experience with computing tells me that we should leave the universities out of it, although London Met had a good rep when they started.
What we need is qualified people overseeing the process, and not bureaucrats. By all means subject it to quality control, but the schools certainly need references from which to teach and by how much. In theory, if the questions matched the syllabuses they could introduce new questions every day and nobody would notice.
Right now, this can't happen because no school I know has any faith in the database, either because the questions do not match the LOs or because around 20% of the questions are actually wrong (having said that, I know that recently added questions do go through stringent quality control, so perhaps there are some old stragglers around).
So, you can't blame people for bashing the database, because otherwise they wouldn't pass at all, but it is not satisfactory by a long way.
