11 Plus pass marks and standardised scores

What age standardisation does

A child born in August is almost a year younger than a child born the previous September, yet both sit the same paper. Standardisation adjusts raw marks for age so that younger children are not penalised. On most scales an average score is set at 100.

How pass marks are set

There is no single national pass mark. Each region sets a qualifying score based on the number of places and the strength of the cohort that year, so the threshold can move from year to year.

Because of this, a useful question is not just whether a child passed a practice paper, but how their standardised score compares with the wider group sitting the same test.

Why ranking matters

Where places are limited and competition is high, ranking against other candidates can matter as much as the raw threshold. Mock exams that report a standardised score and a percentile rank give a much clearer picture of readiness than a simple mark out of ten.
