Hi Grandyma
I think it's more important how your granddaughter did, rather than how other people's grandchildren or children did, isn't it?
I can totally understand why PSLE parents are checking out JCs' Mean UAS, subject combi as they're shopping for DSA-sec schools. I can also understand why parents of upper secondary school children are concerned about JC subject performances as they're going to pick combis or have already picked their combi and so are keen to suss out the standard of the seniors and respective depts' performance vz the national standard for planning purposes.
But for you whose granddaughter who was from Class of 2017, what is your main objective for doing this?
How did your granddaughter or daughter fare last year? Is she is one of the 1 in 7, or 1 in 5, as announced by her Principal? Is she happy with her results?
I put it to you that you're just feeling insecure, concerned that your granddaughter or daughter's A level cert value will drop if her JC is one day out-ranked or outperformed by another nearby JC.
Please rest assured, Ah Ma, that GCE Cambridge's As, Bs or Cs will not devalue even if your Singapore JC's Mean UAS drop or rise in the future. What's important is that your granddaughter or daughter gets into her desired university and gets a good job. Also, PSC, local unis look at her UAS, not which famous JC she comes from. Likewise, employers don't care about JC UAS or ranking. A humble person from a mid-tier JC with As/ Bs may sometimes get the job instead of another haughty person from a top-tier JC with straight As all his life.
So, please stop worrying about your granddaughter's JC potentially being eclipsed by other JCs in the unknown future. It's all based on free market forces. Some teens like newer campuses, others like later starting hour and 5-day PE attire. So respect their choices. Life is too short to worry about other minuscule statistics when one's offspring has already graduated. Too much sodium is no good for the elderly.
