I hope that that one mud school isn't there, because what would we found when we inherited those schools after apartheid was that there were thousands of them. It is only the Eastern Cape which had delays in terms of eradicating its mud schools, so I would not be surprised if Natal has dealt with its mud schools. The question you wanted me to answer was about how many mud schools there were. The question is not linked to inappropriate structures, so, there could be other structures that are inappropriate.
Even in terms of the mud schools, there are solid structures that have been built out of mud. If they are safe and solid - I am sure you will agree with me because some of the structures are solid - it does not mean that if it is mud, it must go. It must go if it is unsafe or unsuitable.
I say this because there are good mud schools in other parts of the country. However, I wouldn't be surprised if Natal has dealt with them as they are very efficient. They could even have dealt with this one already and maybe that is where the question about the unreliability of the figures might arise. They have been very efficient in dealing with problems, and maybe it is no longer there. They have not reported that they have eradicated it.
