To give DD school (and the SATs agency) some basic statistical literacy?

DD has her SATs report with her end of term report.
She got 89 in her English grammar and 93/94 in her other English and in Maths.
This has been reported as "not reached standards" or similar by school.
As a PhD in a subject requiring statistics I know that 85 would be one standard deviation below the mean (100) and that scores of between 85 and 115 are statistically indistinguishable from 100.
Put another way, if you have to have 100 to "reach standard" they are assuming that half the children automatically won't reach the required standard.
AIBU to explain this to you and to school and my fellow parents?
DD was in a group of 2 struggling with maths at the bottom of the class for several years and I'm really proud not just that she's progressed but also that she's now in the middle of the national scores.
This is a ridiculous way to "explain" to parents (unless their explanation is wrong and it's not a normal distribution with a median of 100?)

SATs are a measure for the school’s performance , don’t t worry about it

The way they measure the schools performance is through the children's results. Its not like a school inspection where the grading is based on observation of the teachers & the schools policies etc.

As a parent you should pay close attention to your child's scores.

I think progress is used more to measure performance more than absolute results which vary enormously depending on the cohort

The education system in the uk work hard to avoid giving you a crystal clear view of how your child did compared to their peers.

You basically want to know exactly where you child sits relative to cohort. This level of detail isn't helpful in supporting her to progress. If anything op, it will probably make you worry. What you need to know is she is at the low end of the cohort and you should expect her to require additional support at secondary.

They don't release all the very specific data because they would have to do it throughout the ranges and it would become something parents would obsess over (most parents also are not statisticians and would misinterpret). Being greater depth wouldn't be enough and you'd have a whole chunk of parents getting cross with school if their child wasn't in the top 1% or whatever.

They do release the score by score, percentile by percentile data, every year.

They are used in secondary for predicted grades in all subjects, so will determine sets and be used to ensure a child is making good progress

THIS!

MadKittenWoman · 21/07/2025 19:11

100 is expected achievement. Less than this is standard not achieved. 112 is greater depth.

Thank goodness the OP started this thread before emailing the school.

That would have been… embarrassing

although given head a good chuckle

You've assumed the mean, the standard deviation and the fact its a normal distrubution.
Maybe you should redo your statistics GSCE.

Dizzybob · 20/07/2025 14:13

For the spelling and grammar test a scaled score of 85 means the child got 8/70, scaled score of 100 means they got 35 or 36/70 and 115 means they got 60/70.
They’re not similar scores at all.

Even if it were a normal distribution, the assertion that scores between 85 and 115 are statistically indistinguishable is a stretch.

There clearly is a vast difference between a score of 85 and 115 in any scenario

Exactly, especially when the lowest score is 80 and the highest is 120.

I'm a secondary maths teacher and there is a huge difference between an 85, 100 and 115 scaled score

I mean, this is bollocks.

They are a measurement of the child's ability (to an extent, all assessments are flawed).

AS WELL AS THAT, those results then provide a measure for schools to be monitored on how much progress their children have made and how much 'value added' - where children have done better than their previous data predicted.

To say that it's only for schools and not to worry about it is ignorant and doesn't help you to support your child with their school career.

SATs do not assess whether kids are nice kids, future Olympic gymnastics, going to be an amazing community advocate etc - but that's not what they promise to do! Our kids are more than JUST SATs, but their academic attainment is part of the whole big picture of who they are.

OP hasn't said where she's going. The majority of students will go to mainstream so it's reasonable to assume that she will be in a relatively large MA class.

Hopefully she's going to a smaller provision to get the support she needs.

It has also stated up front that she will have support in place for September has additional needs joined with no sets etc

allthesmallthingsarehere · 20/07/2025 12:04

Inthecafe · 20/07/2025 11:55

Must be pretty entertaining though

especially as the op mixed up mean and median in her explanation!

Tricky when you can't say out loud what you're thinking in your head but I have been known to send home 'age-appropriate' information to correct any misunderstandings. Parents don't often appreciate being given a y2 explanation though when they started the conversation with "well I went to UNIVERSITY and...".

This thread is the PERFECT example of why teaching is so hard when you have to interact with know-it-all parents 😅

You're mithering over something that makes no difference to her in real life. It doesn't matter what the confidence interval is, her scores are low, so it's time to support her.

Do they really not set for Maths? I'd want to know how they were going to manage her in a mixed ability group and how experienced the maths staff are with teaching mixed ability. I'd be very concerned she will become invisible.

Not all schools set depends she may be going to a Sen school on an independent school.

my daughter has 7 kids in year her class in September ( year 7 ) mixed ability is fine in small classes.

Hercisback1 · 20/07/2025 08:05

drspouse · 19/07/2025 16:46

They don't set students in her new Y7 - but as I've said upthread, we already knew she's getting some extra help.
Another poster suggests between the 5th and the 10th centile but again, because I like numbers, I'd like to know the confidence interval - it could be "really" the 1st to the 30th, or the 4th to the 11th.
I know, I'm weird, and the odd non explanation on the report didn't help at all.

Yes that's pretty much it but without any set boundaries except "expected standard" (100) and "exceeding the expected standard" (110) (or whatever the wording is.)

Your daughter is a rock star and I hope she has lots of lovely things ahead of her this summer.

Awhh thank you
I try to never to compare her because she has been on her own journey we just focus on what is what at the time. We were very happy with her SATS results although I will say her high need VS her academic ability did cause a lot of work for the LA to find her a school 😂😂

JassyRadlett · 19/07/2025 19:26

Timegoestoofast · 19/07/2025 18:45

So if we were comparing in other exams like GCSE

4 is a pass but a low pass then you have 5 pass 6 7 8 etc

then you obviously have 2 3

so I’m assuming like 100 would be in that sense “4 “
and 107 “ 6 “

4 is a pass but not the average score nationally.

OP your time might be better spent looking to be kind to others rather than criticising them over their statistical knowledge, especially as yours doesn’t seem that impressive.
Teachers have a really hard job. I’m a TA, the pupils I work with scream, shout, threaten to punch me, try and punch/hit me, overturn furniture, it’s really hard.
I find it a bit petty that you are blaming the school for something the government do and criticising them because your statistical knowledge is oh so much better…

Why don’t leave the school alone, think of something positive to thank them for and move on, focusing instead on your daughter and all she has achieved despite her challenges. It will be much better for your mental health.

This. You are lashing out because your daughter's inability to reach 'expected' has touched a raw nerve because you are not confident in your own abilities. And your condescending arrogant post which was supposed to show everyone how much smarter than the sats system you are has shown the diametric opposite.

TheNightingalesStarling · 19/07/2025 18:45

O0, all these tests have shown is that AT THE MOMENT, she is below the expected standard for end of Yr6.

It doesn't say how hard she works or what she is capable of in the future. Its in her second language, she's had more obstacles than the vast majority. She's also got a parent that seems very able to advocate for her and to help her.

Ignore what other 11yos can do and concentrate on her needs and what support she needs.
