I see thanks verykiasu2010, I did not know this information was so widely available.

I am much clearer about this after reading the info you have given.

credit must be given to the principal of NUSH - he is the one who devised the t-score formula, so i heard

[quote=\"coolit\"]Thanks verykiasu2010, your explanation is superbly clear. Where do you get this information?


So I can say that if the papers are all relatively easier, the average is higher but the high scores are lower?

the explanation can be found all over internet. the para is copied has been credited to wiki, referenced above

you are right to say that easy paper -->high average --> low t-score

assume everyone in the cohort gets 100% for all 4 subjects : mean = 100, variance = zero, SD = zero, t-score for each subject = 50, max t-score for the psle = 200 when everyone gets 100% for all subjects

presently NYPS website also has a complete explanation with ppt for the PSLE t-score calculation. download it for your record and use.

Oic .... But if i get 200 t score with perfect raw scores ... I wouldnt feel Gd.
:skeptical: ..must get 300 t score ma [/quote]if the papers are super tough, everyone else score less than 10% and your ds scores near 100%, his t-score will be in the 10s thousand or more

Huh ... More then 300 t score u mean, vk2010? Tts cool :imcool: .. Will dream on hahaaaa

you actually don't need to work extra hard to achieve that. just wish everyone else do badly, very badly, and your t-score will be higher

t-score = transformed score. it is a ranking measurement, not an indication of how many marks you scored

I used to mistakenly think that max is 300; but if you play with the formula, there is no max, and in extreme cases, it can be more than 10 or 20 thousand for t-score...but given the cohort size and the normal distribution characteristics of any cohort's performance, it hardly reaches above 295

my DS used to say he was aiming for 303....aim only haha

Ya if got such abnormal Case which mean very difficult papers .... Many parents would make noise Liao :rant: .. I think moe would not allow tt to happen

Hi all,


I m just curious on the grading for higher MT. All I know is Distinction, Merit or Pass. But do they based solely on raw scores? If so, what is the mark range for D, M and P?

Sorry … But I m super blur on this.

Good question paddy field as I also not sure. I only know to get distinction one must get 80 and above...
Emmm ... I think since it is not going to add on to the total score... So logically no need to convert raw score to t score .. Which serve no purpose ..

I thought it was 80 all the while to get distinction. But DS's Chinese teacher told the class 85. I was totally confused. Anyone else can confirm?

Yep, Dr Hang Kin Boo, current Principal of NUSH was the one that proposed to MOE years back. He was a statisician with a Maths Phd. That's why he knows that student who can scored well in MT (chinese, Tamils, Malay) etc aways has the edge in achieving higher T-score than his chinese, tamil or malay compatroits. That's why you cannot compare T-score at face-value meaning you cannot compare a chinese vs malay vs tamil PSLE candidates.
You will always have a top chinese, a top indian or top malay candidate.

The Indian and Malay pool of candidates is much much smaller than those taking Chinese as mother tongue. The SD and the mean of Malay and Indian is different from Chinese. If you have a year of very tough Malay or Indian paper and a generally easy Chinese MT paper, the top student will be from the Malay or the Indian PSLE candidates , all other things being equal.

Many folks here probably did;nt know about this.
