What does a standardised score actually mean?

A standardised score converts a child's raw marks onto a common scale and adjusts for their age in months, so children born earlier or later in the school year are compared fairly rather than by raw marks alone.

Why does my child's exact age affect their score?

Age adjustment exists because a child born in September has had almost a year longer in education than one born the following August. The standardisation process corrects for that gap so the youngest children in a year group are not disadvantaged simply by their birth month.

Can you tell me the exact score needed to get into Kendrick or Reading School?

No, and we would treat any tutor who claims to know one with caution. Neither school publishes the score that filled the last place in a given year. Numbers quoted on parent forums are unverified self-reports, not official figures, and we do not repeat them.

Standardised scores explained: why there is no 11-plus pass mark

Q: Is there a pass mark for the Kendrick or Reading School 11-plus?

No, neither school sets a fixed pass mark. Both select by rank on a standardised score, so the score needed for a place changes every year with the strength of that year's cohort.

Q: Does a high standardised score guarantee a place?

No, not on its own. Kendrick has offered no place to a child living outside its designated area since 2013, whatever their score, and Reading School allocates places within oversubscription categories that include catchment. Confirm where you stand on catchment before assuming a score alone will secure a place.

No fixed pass mark exists for Kendrick School or Reading School entry. Both schools select by rank on a standardised score, so the score needed for a place changes every year with the strength of that year's cohort. A score that secured a place last year can miss out this year. A lower score can succeed against a weaker field. Standardisation converts each child's raw marks onto a common scale and adjusts for their age in months, which is why the number on an offer letter is not simply marks out of a total.

What "standardised" means in plain English

Standardisation turns a raw mark into a comparable score. Test providers convert each child's raw marks onto a fixed scale, typically centred around 100, using a statistical process that accounts for how the whole cohort performed on that particular paper. Age adjustment is built into the same process. A child born in September has had almost a year longer in education than a child born the following August, so the score is adjusted for age in months to stop older children in the year group holding an automatic advantage. The result is a single number that lets a school rank every applicant fairly, whatever their birth month.

Entry is by rank, not by a fixed mark

Rank decides the outcome, not a target number. Schools order every standardised score from highest to lowest and offer places from the top until the places run out. The score that fills the last place is set retrospectively by the cohort itself, not fixed in advance by the school. A strong year group pushes that score up. A weaker year group lets it drift down. Any number described online as "the pass mark" is really a description of a past year's competition, not a target this year's children are aiming for.

Kendrick and Reading School standardise differently

Kendrick and Reading School use different assessment providers. That difference matters for how a child prepares. Kendrick's papers are standardised by GL Assessment, a national provider used widely across grammar school admissions. Reading School uses its own assessment run by FSCE Ltd, which changes its content every year and states plainly that its published Familiarisation Guide is not a definitive guide to the test. Two children with the same raw ability could see different standardised numbers simply because they sat assessments built and scored by different organisations.

Catchment can decide it before the score does

Catchment can override the standardised score entirely. Kendrick has offered no place to a child living outside its designated area since 2013, whatever score that child achieves. A high standardised score does not overcome an out-of-area address at Kendrick. Reading School allocates places within oversubscription categories that include catchment and named feeder primaries, so where a family lives can matter as much as the number on the results letter.

Why we will not repeat cutoff numbers from forums

Specific cutoff numbers circulate widely on parent forums, claims like a child on 112 was waitlisted while a child on 118 was offered a place, or that 882 girls sat for 96 places. These are unverified, self-reported numbers, not figures either school publishes. Neither Kendrick nor Reading School releases the exact score that filled the last place in a given year. A single forum post proves nothing about how representative it is, whether it is accurate, or whether it even relates to the year a child is sitting. Repeating it would give parents false confidence in a number that carries no real weight.

What this means for your preparation

Preparation should target strong performance, not a mythical number. Aim for a child to perform as well as they can across every paper, because the standardised score rewards consistent strength across the whole assessment, not a lucky pass over an imaginary line. Confirm catchment and oversubscription rules early, since they can decide the outcome before a score is even calculated.
