Dr. Harold Hislop:

It was considered. The possibility of using teacher estimated marks unadjusted was considered but it was very clear when that data came in from schools that different schools and different teachers within individual schools had over-estimated the likely performance of students at very different rates.

When the data came from schools, it was clear that different schools and different teachers within individual schools had overestimated the likely performance of students at very different rates. We would have ended up with some cases of schools and teachers, and individual teachers within schools, awarding grades with little or no overestimation and others awarding grades in the same subjects where severe overestimation had happened. We would have been leaving that inequity in the system unadjusted.
