Ms Andrea Feeney:

One of the underlying principles relating to calculated grades is that schools are good at knowing how schools perform in their local context. They know how their students do in the context of an examination held in the school because they are able to make that call in their local frame of reference. However, schools do not have the knowledge to be good at understanding where the school is performing in respect of the national standard, which is why we had the national standardisation process.
