It is hard to say, why parents should be so upset with the recent PT3 results.
As an educationist, I am not into the idea of mass instructions reflected by this centralized series of exam. There are so many reasons, be it economic, political, cultural, or even psychological, why the exams fail to serve justice. Students are individually unique and the standardized exams are always good at ignoring them.
Teachers and schools know their students better and school should have the autonomy to design the assessment based on the uniqueness of each institution. At least, part of it is exercised through this new PT3 where marking is not centralized. And the poor result should be taken as a measurement for improvement at school level, rather than blaming here and there.
There’s nothing to be upset. The result does not determine anything. Not even SPM, not to mention the future of our kid.
