How to gauge potential tscore from prelim

[HeSheMe]

From what I have experienced, about 80% of all the primary schools in Singapore have their prelims harder and more difficult than the PSLE. Yep, and this is of course to prepare them for PSLE so that it seems that PSLE is much easier for them. :boogie:

A few of you mentioned that to add x points to prelim t score to estimate psle t score. But in the first place the school only provide scores which is upon 400, and t score uses formula with mean and standard deviation. So how do u estimate t score for yr Prelim results in the first place? Or some schools provide thier own school Prelim t score for each child? I estimate my

Sons p6 t score based on the report book provided mean and standard drviation. But like I said it gives me a scare of my life!

a number of schools do use the prelim results and compute the t-score out of it, just like psle score, and track the prelim t-score year by year in comparing with actual psle t-score

in fact NYPS does the t-score from pri 5 result onward

Thanks verykiasu2010, that explains. My son’s school does not provide T-score. so i had to DIY.

With mean and SD you would be able to estimate T-score relative to school mean. To adjust from school mean to national mean, you can add the difference between school and 200. If the school does not publish the past mean t-scores, see if you can pick it from the \"unadjusted\" estimates posted 25 April 2011 17:29 on the following page. http://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=5&t=16430&start=20.
For example if your child is from ACSJ, the unadjusted estimates for 2010-2008 are: 225.2, 219.7 and 215.5. So you need to add 25.2, 19.7, 15.5 from your own first estimate. Where your child's actual cohort does relative to national scores varies from year to year but is relatively stable. Difficulty of paper from school to school is hard to compare. Good luck.

One caveat to the previously mentioned adjustment between school mean and national mean: For difficult prelim papers and where the student’s scores is high, the estimate from prelims is likely to be higher than what’s for PSLE. This is because top schools prelims are difficult and the top students have more room show their abiltiy to get a high t-score in that subject compared to the PSLE where it is easier. This is why when the PSLE papers are hard, the top national scores tend to be higher. For the average student in a top school, the method is not too far off.

I got 333/400 for prelims. What is my likely t-score with this mark?
