Does he know what Z-SCORE is? Does he have an ounce of stat knowledge?

There is nothing wrong with the z-score system, the blunder was done due to non existence of proper technical personnel and minimum supervision and test checking.

Z score calculated for two populations have combined wrongly.

Statistically what is given as Z score result is not actually a z-core. Therefore Island ranks do not reflect performance and the merit order. It is very unfortunate situation for the university education of this nation. Can the university education sustain and move forward in this nation without correcting such a grievous error.
It is a crime to move forward without correcting these errors as it has been highlighted by several academics. Present generation clearly understands and they are aware of the fact that that there is a serious error in calculation of z-score results.
There are no two methods to calculate z-scores in statistics. Anything other than that is not z score, it is a distorted figure. There is a single well define universally accepted methodology for calculation of z-score.
