Standardlise Scores
Hi,
Can someone explain what is standardised score means? Is it different schools have different "formula" then adjust based on your child's age? For their formula, do they define a "x" number of students for a specific marks so they overall say 115 to 136 (example as Slough's scores) will be their total number of available spaces?
Thank you !

Re: Standardlise Scores
A standardised score indicates how your child ranked in the test. There are different reasons for the differences. One example is the different cohorts sharing results and another reason is the schools may choose to give some papers more weight than others.

Re: Standardlise Scores
There is no penalty for a particular age
All they do, is look at everyone born in August (about 500 kids if there are 6000 entrants for the Slough exams).
they look at the kid whose raw score puts them *exactly* into the top 30% of score (ie they rank 150 out of the 500) : and that raw score is converted to a standardised score of 111.0 and the kid *just* passes.
Every child who got a better raw score than that will pass, their scores will be higher according to how well they did.
Every child who got a worse raw score will get less than 111.
everyone born in September (about 500 kids) they then do the same thing again so that the top 30% of those children will pass.
Everyone born in October, they do the same thing again.
Doing this seperately for each month of birth removes the “advantage” of a child being 11 months older than some of the others sitting the same test.
make sense?

Re: Standardlise Scores
Thank you so much both your reply.
In that case, there is no "safe" score at all because this year can have lots of kids having scores at say 120-125 comparing the last year?
However looking at the past year records, it always is around 116-118 (e.g Reading boys and Kendrick) ? It seems strange if every year the same amount of kids having scores above the very similar cut off marks?

Re: Standardlise Scores
Hi,
The way it was explained to me (mainly through links on here so many thanks) is:
1 they take each child's raw score (so the number of questions they got right), add them together and divide by the total cohort to get the average.
2 this average is then called '100'.
3 each child's raw score is compared to this average and given a corresponding mark (so if their raw score is better then the averaged raw score they will be over 100, if it is lower then they will be below 100).
4 they do the same exercise for each birth month, which means they are compared with DC the same age (as you can't really compare an August borne kid with someone born the preceding september).
I remember seeing graphs explaining some of this, like the bell curve and how the top 30% get 111+, but I can't remember a lot so do apologise. Hopefully a forum member can help with the relevant links as the posts were on here.
