Last year (2009) EESIS was 261. They year before (2008) was 263. The drop of 2 points in EESIS caused almost all the schools COPs last year to drop 3 ~ 4 points.


If 260 is the COP for EESIS this year, then we can expect the COPs for top schools to be slightly lower than last year.

Agree, you make a lot of sense. This year's top schools COP will be a touch lower. And 260 is EESIS for this year.

It is relatively well known that they always draw the line of t-score 250 at the 90th percentile mark, i.e. top 10 % = 250 and above. Am I right ?

I think the method of setting the mean as 50 per subject and giving 10 points for 1 SD is confirmed. It produces a 90th percentile that is roughly around 250 but the evidence does not support Tscores moderated such that 90th percentile is set to 250. Just like I dont think the max Tscore is 300, in practice is seems hard to surpass that 300 given that the exams are set for the general population. If PSLE were to be olympiad standard, 300 would regularly be exceeded.

Not sure your DS or DD from which school.


But my DS & DD (both different school), the report book includes a Table of the Max, Mean, Min and Std Dev of the class and level. So you can work out the T Score base on the info in the table by putting in the respective info into the fomula.

But how much the schools Deviation from PSLE result, only the school keeps the info, it is not publish.

My children's school dont publish SD, but do indicate mean for each subject; so I estimate SD. In my opinion, one practical way of estimating a child's Tscore is to first calculate Tscore relatively to school mean, then adjust it by difference between school PSLE mean and 200. Problem often is that one doesnt know the school's PSLE mean which this sheet estimates using quality passes.

My observations are:
1) Mean scores for a school are relatively stable over the years
2) And so are the corresponding quality passes.
3) PSLE is highly likely to be moderated otherwise how come every year the quality passes, express stream percentages are stable despite people complaining about the difficulty of the exam.
3) Each SA and CA mean is not that stable, so multiplying by 0.7 as some people suggested does not work well. Good school standards are so high that even max scores dont reach 90, whereas some students on this site report 95 for english.

If you put in 80/80/72/93 which is what I find on the net about RGPS's aim for PSLE 2010, you get a number close to the 234.7 reported for RGPS 2009 PSLE. I posted this on the RGPS page a few days before the report.

Just wanted to share a little spreadsheet which I used to estimate a school’s mean tscore. Since I cant post the worksheet, I just paste the excel formula:


__ A ____ B ___________ C
1 _____ %A/A* _______________________
2 EL 44% ____ =101.51-NORMINV(1-B2,50,10)
3 MA 44% ____ =101.51-NORMINV(1-B3,50,10)
4 SC ___44% ____ =101.51-NORMINV(1-B4,50,10)
5 CL ___ 81% ____ =91.22-NORMINV(1-B5,50,10)
6 Mean _________ =SUM(C2:C5)
7 Adjust ________ =C6+7+(200-C6)/6

Input the % of quality passes (ie A/A*) for each subject and it estimates the mean score of the school. There’s also an adjusted number as some schools give only the means for those taking 4 standard subjects only.
It assumes 81% A/A* for CL and 44% for the rest. Top school means should be closer to unadjusted mean

Since PSLE results will be out next week, it would be interesting to see how this lines up with real data which I have only a little gleaned from the web. Last week’s MM visit to Punggol and RGPS provided some useful data points. So if parents can share the %A/A* and compare the estimate vs real mean Tscore from the child’s school, it might be useful.
It’s hard to get MEAN AGGREATE score as many schools dont publish on their websites but may mention during private sessions especially on results day.

I am just wondering if we strip out GEP's contribution, what will be the mainstreamer's aggregate PSLE score at RGPS?

From straittimes, 85.6% of total qualify for express. A bit low compared to info on this website on Tao Nan or MGS (non GEP school). My guess is RGPS mainstream will be a slightly below MGS. (no offence intended).

autolycus has already given a detailed picture. I dont have any info on the Y1-4 program; just wanted to highlight the fact that many IB schools internationally dont do the MYP. Kinda of like the diff between ACSI and ACS International. Name might be similar but significant difference.


I’ll be very surprised if Y1-Y4 IP followed the MYP; expect it to be closer to other Singapore IPs.

The IB Diploma Program as far as I know, refers to Y5 and Y6 program leading to the IB exam. Many overseas schools when they advertise IB mean they follow the final 2years of the IB. Before that, it could be various diverse programs as the IB Middle Years (ie Sec sch) program is not that popular.

Kiasu Friend:

What is the CoP for IB intake for year-1 in ACS(I) last year through PSLE Centralised posting (i.e., from non-affiliated schools)?.

IB COP was 255 for 2010 intake; 257 for previous 2 years. The 257 is probably from a school letter somewhere in cyberspace, and 255 was from friend. Since I didnt call the school, take it as unofficial although I think the numbers are accurate. No discount for affliated schools.

Your estimate is accurate. Occassionary I do see wrong figures/info being given in this forum but I choose to disregard it. With 37.5% of pupils unable to make the express stream cut, the mean PSLE T-score is approximately 205. The three best performing schools are NYPS,RGPS and TOA NAN.

No school has more than half of its pupils scoring 250 above.

For a while now, I've been puzzled by schools indicating that the National average PSLE is around 207. I thot that the avg T-score would be 200 by design. I fudged my 215 estimate; the unfudged score is 212 but decided that adding another 3 (out of the 7 difference) would be closer.

My guess about top average T scores is probably NYPS although it's entirely anecdotal as I dont have data. MGS probably has slight edge over Tao Nan, and perhaps about same as RGPS (no data except 2010 \"aim\" which I take to be close to past performance).

%A/A* EL Maths Sci CL
2007 TaoNan 86.1% 71.5% 73.4% 90.8%
2010 RGPS aim 80.0% 80.0% 72.0% 93.0%
2007 MGS\t 90.6% 74.5% 81.3% 84.2%

Data comes from internet, estimates are my own. My child's school doesnt do T-score estimate so had to do my own estimates. It has been interesting speculating about each school's score based on publicly available data. Schools tend to be coy about avg T score and many only reveal the A/A* % which I think is useful to estimate the average T score.

I see, how would this result fair relative to the other schools like Tao Nao, St Hilda's and Maha Bodi? My niece who's from Maha Bodi told me her school also has an average PSLE score of 230 to 240. Impressive, if her stats is right.

I estimate Maha Bodhi 2009 avg T-score to be about 215 based on their published A/A* results for EL/MA/SC/CL results of 50.4/55.5/51.9/90.8.
Estimate RGPS to be around 232-235 based their published 2010 target of 80/80/72/93. Whilst RGPS and Nanyang supplies the largest number of students to RGS (partly due to GEP), the majority of students at RGPS certainly dont end up at RGS.
