How are the results calculated?

Modified on Mon, 30 Oct 2023 at 03:32 PM

The advanced psychometric technology used provides scores that are based on the difficulty of the questions the applicant sees and whether they answered correctly.  This score is transferred onto a scale with an average of 100 and a standard deviation of 15 based on the performance of a large group of pupils.  This means that around 67% of pupils score between 85 and 115.  16% will score over 115 and under 5% will score more than 130.


In transferring the score for any individual test taker, comparisons are made with the results of pupils the same age.  This means that there is no advantage for older children or disadvantage for younger children because of the different time spent learning and developing.
