2010 PSLE T-score

my DS is from one of these 'top schs'. When the pre-lim T-scores were released, his cohort was advised tt those who scored 225 or more should hit 250 n above in the upcoming PSLE. Based on past data, this seems to be largely true for most pupils from his sch.

did the sch estimate the t-score using SD and mean ? is this estimated t-score close to using 'Total x 0.75' formula ?

I think total x 0.75 is not the formula. It is at best a guesstimate

if the poster \"naggo-nitemare\" for the \"225 and above\" is NYPS kid's parent, then they are using the actual formula from MOE, and threw in all the data from the NYPS P6 kids' prelim marks, they actually have two sets this year, one set for mainstream only, the other set is on the whole cohort mainstream plus GEP scores all computed together. they calculate the SD and the mean for each year's exam for each subject

from past years' records, NYPS kids actual PSLE performance are about 15 to 70 points higher than their prelim t-score calculated by the school

and the school tracks the kids' t-score from P5 SA1 onwards

T score is how well you perform in relation to others. And sentence construction? Since when was there sentence construction in chinese? Unless you mean question 7-8 完成句子?

Sorry for not being clear. T score for Chinese will be affected by the change in the exam format. When the paper was simplified, the mean became very high - because both local and foreign students' score improved.

Before the simplification of the Chinese exam format, the 3 killer sections in Chinese paper 2 were : \"correction of wrong words\", \"constructing sentences with a given phrase\" and \"rearranging the sentences. My youngest kid was the worst in Chinese yet she did very well in PSLE, all because of the change in format with all the 3 sections removed.

Therefore, I was guessing that with the change in the format again this year, which I understand to be with the inclusion of \"constructing sentences with a given phrase\" (not sure if I got it right), the overall average marks (mean) may drop. This will help in the T-score of below average students because with lowering of the mean, their T-score will be reduced by a lesser amount as compared to a high mean score.

Don't think there is \"constructing sentences with a given phrase\" in this year's CL PSLE format.

Yeah, me neither. But I think it will come out in the HCL Paper 2.

Do you think psle 2010 t scores will be high due to papers being easy? Will schools COPs increase then for sec 1 2011?

[JonC]

Easy papers mean the bell curve will shift towards higher grades, so the upper grade range will get narrow, the middle (so call the 50/mid T score point will also shift upwards. The lower range will get bigger.


Ultimately, the final outcome (T-Score) and number of people in each range may still stay around the same yearly. That is usually how bell curve works.

I maybe wrong, any expert in Statistic around here?

Easy paper means the TOP T-score will decrease but the COP may increase because there are many students with about the same T-score in the top 75%

dun think will be high, ard the same or even slighlty lower than last yr, not exceeding 290
for COP for most sec schools and esp the 7 new IP schs
would think it'll go up, abt 2 points or so..........
