Standardised scores

[Hardwork786]

Could someone explain to me how the standardised score works. If three children scored the exact same mark but one was born in Sept, the other in Feb and the other in August, what would their final scores look like. Thanks in advance

It's impossible to predict precisely.
They all compared with other children born in the same month. Marks are not added or taken away depending on age as such

Typically younger children get lower raw scores, but it's not always the case.
