## All About T-Score

### Re: All About T-Score

info from 1 of the pri school website,

(

PSLE T-score

• How is it calculated?

T = 50 + 10 (X – Y) / Z

X is the pupil’s mark for the subject

Y is the average mark (mean) scored by all the pupils

Z is the spread of the marks around the average mark

(standard deviation)

We have no way of ascertaining what the Y and Z for any particular exam is

Pupils need to put in their best effort for all subjects

• All 4 / 3 subjects that the pupil offers carry equal weighting.

• T-Score is not the mark that a pupil obtains in the examination.

• T-Score gives the rank or position of a pupil’s performance compared to all other pupils in that subject whereas the mark obtained in the examination only shows how good the pupil is in that subject.

• All subjects are important in terms of getting as high a PSLE T-score as possible.

• The higher the PSLE T-score, the more choices of secondary school.

### Re: All About T-Score

My dd3's school provided the mean and standard deviation for each subject in the prelims. Hence I was able to get her prelim's T-score, which coincidentally, also reflects her psle T-score.(difference of 0.3).John Lim wrote:info from 1 of the pri school website,

Of course, we don't know the raw, mean and sd for psle, just that the score happens to be so close.

Yes, this tools is useful provided the school give the mean and sd score.Pepsi wrote:Incredible, my ds psle T-score was exactly his prelim resultJarol Lo wrote:I find that this link is useful.

If the child primary school standard is above national average than estimate a few points up. If the school standard is below national average than deduct a few point down.

### Re: All About T-Score

I'm curious to know how the Geppers fare in the psle. Since they have been specially picked to join Gep, I suppose they must have been within the top 3% of the cohort?

Do their psle score fall into the top 3%, or even the top 1% of the cohort?

Just to share:

My friend's dd had the same average score of 87% in the prelim which is quite similar as your ds result. Using a simple 0.72 x 87 x 4 will work out to a T score of 250. This was exactly what her dd scored for PSLE this year .Her prelim result was the same as PSLE T score if used 0.72 as a rough estimate .She has tried for Cedar academic DSA. But was not even shortlisted .

T-score also factor in the individual primary school's overall P6 psle students' cohort performance, not just based solely on individual student's marks for the 4 subjects

Key question is :

do you happen to know how your child's primary school P6 cohort performance ?

Unknown for Mean & Std Deviation mean we could not determine the T-score. I wonder could we able to obtain this or should the school give us the score for the SA1?phtthp wrote:T-score also factor in the individual primary school's overall P6 psle students' cohort performance, not just based solely on individual student's marks for the 4 subjects

### Re: All About T-Score

If the school is willing, they can use the school results to compile the mean, sd, etc and compute the t score of the kids using the school results as a cohort. The school can then benchmark their school t score versus actual psle t score on the national level and see how their standard differs from national standards.titank wrote:Unknown for Mean & Std Deviation mean we could not determine the T-score.

Those well known schools have been doing that for years
