11 Plus pass marks, explained

Raw marks are not what anyone means

Your child answers a paper and gets a raw mark: so many right out of so many. Almost nobody ever sees that number. It goes through two adjustments first, and what comes out the other end is a standardised score.

Standardising, and the age allowance

Standardising converts the raw mark onto a common scale so that papers of different difficulty can be compared, typically centred on 100 with most children falling within a band either side of it. A score of 100 is, roughly speaking, average for the cohort.

Before that, an age allowance is applied. A child born in August sits the same paper as a child born the previous September, up to eleven months older, at an age where that is a real difference. The adjustment gives younger children a modest uplift to compensate. It is automatic, it is small, and it is not something you can influence.

Why there is no fixed pass mark

In most areas the qualifying score is set after the exam, not before it. The school or consortium looks at how many children sat it, how they did, and how many places there are, and draws the line accordingly. That means the number depends on:

• How many applied that year.
• How strong the cohort was, which varies.
• How many places the school has.
• What the school is trying to do: some set a qualifying bar and then allocate by distance, others rank purely by score.

So last year's figure is a useful sense of the neighbourhood and a poor target. A child who lands exactly on last year's number has not passed anything; they have scored what was enough last year.

Qualifying is not the same as a place

In many areas, clearing the bar makes your child eligible and nothing more. Places are then allocated on the school's oversubscription criteria, which usually means distance, catchment or siblings. A child can qualify comfortably and still not be offered a place at the nearest school, which is a hard letter to receive and much easier to plan around if you were expecting the possibility.

At super-selective schools, which rank by score alone, the score is the whole decision and the effective threshold is usually much higher.

What this means for preparation

Aim for comfort rather than for a number. The realistic goal is that your child finishes the paper, gets the questions they know right under time pressure, and does not lose marks to rushing or to a vocabulary gap. Chasing a specific standardised score is chasing something nobody can calculate in advance, including the school.
