All along I thought psle raw score of A*/A/B/C etc is based on bell curve rather than true 91 marks etc.

You know, that’s why our G design a section known as FAQ... BUT we all know no one ever reads them.

From https://www.ifaq.gov.sg/seab/apps/fcd_faqmain.aspx?qst=hRhkP9BzcBImsx2TBbssMsxu7lqt6UJK70a1wAEVmyfdSZlp3kC3qEU1uwdD2zxBC8h26bwjs%2FIwvamUXpJQllIbGr3zfx%2Fg6R5G3kQwdaBqrmc6VVtGVreSd34s3fzQd2XjpEaXHjFH9k4Aky4ad22Tv9ZVP3e82AhV2YIeMwaGIBKFIrvh5zfUcyEdjkBGvw8b%2Bh1woqMmu1%2FCwl6UK4xSGccfs%2FuC2rGMLPsW7lE%3D#FAQ_93280:

What is the difference between a student’s grade and his T-Score?

The grade indicates how well the child has performed in that particular subject based on an objective set of standards. His Aggregate T-Score indicates how well he has performed on average in all four subjects relative to his peers and is used specifically for the purpose of determining the priority of admission to secondary schools and the eligibility/fit for the different secondary school pathways available

The T-score methodology is like the hunger games. May the odds be ever be in your favour......

Is this something new, as I always thought there was so-called bell-curve?

This was in response to a forum letter re an outgoing SMU lecturer's generous awarding of As to his students.

PSLE T-scores are not forced into a bell curve, according to MOE spokesperson. I think he meant the (final) Aggregate T-scores aren't forced into a (national) bell curve, which is correct. :scratchhead:

But each subject should have its own mean (m) and its own standard deviation (d). There should be 4 subject bell curves (irrespective of whether you want to plot or not), 4 pairs of m and d, otherwise how to compute the individual Subject T-scores to sum up to get your Aggregate T-score?

so nobody knows whether A* is 91 or not right? I have a feeling it is according to bell curve. My kids can't possibly get above 91 for both E and CL

It is not a bell curve.
A* - 91 to 100
A - 75 to 90
B - 60 to 74
C - 50 - 59
D - 35 - 49
E - 20 -34
U - < 20
Why you got so little faith in your kids? :rotflmao:

How far apart was your kids E and CL prelims marks from 91?

Maybe PSLE marking was more lenient compared to your kids' school?

[Imp75]

Prelims Low 80s

\"There's only one probable explanation for this - that besides moderating the t-score, MOE also moderates the grades. It was like a light bulb went off in my head and set my thinking on a whole new trajectory. In other words, the cut off score for an A* can vary each year, depending on how well the cohort performs. It's just a matter of deciding what percentage of kids get an A*. \"

Firstly, I always find it puzzling to hear people talking about 'moderating the t-score'. There's no need to moderate the t-score. The t-score is based upon a normal distribution; it 'moderates' itself (through the standard deviation).

In addition, the t-score, in itself, is meaningless. It's simply a number that tells you how far you are away from the mean and which SD you are in based on the cohort of a particular year (hence, comparing t-scores across years is another meaningless exercise).

However, a much more interesting question is whether the raw scores are 'moderated' based on an objective set of standards to fit a 100 points scale. In other words, a cut off that changes from year to year. That said, it is still not a bell curve, as grading on a bell means every A* would need to be balanced out with a U or E.
