SINGAPORE - Mr Ng Qi Siang's assertion that the highest and lowest Primary School Leaving Examination scores reflect the general performance of the cohort, and can be used as a gauge to select secondary schools, is flawed ("Drawback of leaving out highest and lowest scores"; Tuesday).
The highest and lowest scores are those of extreme outliers and not an accurate representation of the performance of the general cohort. Knowing them is unhelpful for most candidates, whose scores fall in the broader middle range.
Omitting the top score is a right step towards creating an education landscape that looks beyond academic performance.
