[quote=\"alng\"]Hi, anyone knows how to calculate the T-score. What would be the estimated T score for an average of 92%? Thanks much!

it depends that average 92% is from which school? some schools' marks are a consistent gauge of t-score performance every year. for example, if you attend the NYPS briefing at the end of Pri 5, you are usually told that the average increase in t-score from prelim to actual is ranged from 10 to 60, depends on individual's consistency as well

also, 92% for each subject does not translate into same t-score for each subject which is dependent on the mean and the SD of each subject each year

Yeah, there wouldn't be any accurate calculations as the people taking the exams are different and the exam standard is different. For example NYPS top normally ranges between 275-290, yet in Prelim this year, the highest is only in the 250s.[/quote]last year's prelims was 25x - 26x

Does anyone know, for T-score, how are the scores for students taking foundation subject treated?


Thanks

I suspect those schools with GEP classes will face such range of T-scores for prelims as the addition of the \"top 1%\" will skew the Mean and SD of the entire school cohort, esp. since the GEPpers account for a reasonably high % within the small school cohort (compared with national cohort).

I think other then the higher scores of geppers … Usually the top few classes of students of these Gep holding schools, also can score pretty well …

Totally agree. That's exactly the case in DD's school.

Yes. The top mainstream classes do very well in PSLE.

Thanks

They take the same paper so i presume there should be no difference?

hi, anyone has the ‘latest’ T-score formula? Thanks.

the formula never changes

the mean and SD changes every year according to the cohort's performance

ah.. yes, i mean where do get the mean & SD statistics? Thanks.
