Mr. Dalton Tattan:

I do not believe so. We saw through the data that there was some level of underestimation but there was a far greater degree of overestimation. However, the overestimation was not even. In other words, with some teachers within schools and across schools there was a greater level of overestimation in some schools compared to others. To leave that without applying a standardisation certainly would have been unfair.
