That's the bottom line. The standardisation gave no credit for the fact that the school you went to may have been a factor in your progress from JC to LC - that schools actually matter. Of course there are those who would welcome this, in whose view it is basically unfair to be able to "buy" a better chance at LC. These same people would have welcomed the temporary suspension of the advantage for paying for private health insurance. At least this latter group got their money back!If it is a true statement that the school a student attends affects their results then the lack of modeling for a school effect will of course reduce accuracy.
The current model is based on averaging in all national past achievements between jc and lc.
