AIBU to wonder my manager lied about her daughter’s school?

This is crazy. Maybe the school does sats maybe it doesn't. some private schools do and some don't. Maybe she thought the school does and it doesn't. A low ability child can be described as excelling if they are surpassing expectations for them. Maybe she is excelling in another area other than epidemic.
I don't see any of this makeher a liar.
Most likely i think you were banging on about tm your daughter's ability, and she didn't want to piss on your chips

This. Our daughter teaches at a private “grammar” school. It takes children from 3-18.

Absolutely not a personal attack. I honestly think you could benefit from getting some help with things because this thought process isn’t healthy. You’ve got 4 pages of comments disagreeing with the vast majority of people who think this is a non issue and you’re still not willing to let it go. It’s incredibly odd behaviour.

I've not been sarcastic at all, I meant every word. Nor have I made digs. You asked if you are being unreasonable, time and time again you've been told that you are. You won't heed what anyone is saying, so obviously reading the comments is not the same as considering them.

I don't know how often you need to hear it, but as many times as you say the same thing, you are going to get the same response, from me or others. Yes you are being unreasonable.

You're being childish about this whole situation. People are allowed to respond as they wish, you can't police people's responses. You've said move on, don't comment, scroll on to so many people now all because they are not supporting your opinion, or making light of it. There is literally no point in posting on MN if you expect everyone to agree with you. It's a discussion forum, not an exercise in sycophancy.

A very high percentage of people are saying you are being YABU and given you multiple reasons why. Maybe take that onboard. AIBU in not just somewhere to just get "something off your chest". You asked a question and now you've been given a very clear answer. Maybe accept that you are being unreasonable, or don't bother asking people for their opinions in the future. It's guaranteed that they aren't always going to align with yours, so I really don't know what you were expecting.

The thing is. The vast majority of us think you have misinterpreted the situation, which is, after all, a non event. People have explained over and over again why you might be wrong. But you just won’t listen. Then the slow drip feed to get others on side.
Anyway, I don’t think you are really getting anything out of this thread as you won’t listen to other opinions.

This

Oh stop. You’re just making stuff up now to suit your bizarre story. You’ve absolutely no idea what this person knows about assessments her child might or might not be taking in years to come. My kids are at a private school and when my eldest was in year 3/4, I’d have had no idea what tests they’d be taking in year 6.

Honestly, you sound like you could benefit from speaking to someone. I cannot imagine anyone with a healthy mental state obsessing over something like this, it’s really odd.

She might not have known they didn’t sit sats yes she might be involved in school, it may be on the website but she could still have though they did it though or it slipped her mind.

You are determined she’s lied so have you got history of her lying or do you two not like each other?

OMG are you still going on about this. Let it go for your own sanity.

OK so what are you going to do about the "problem"? Confront her? Or just continue to fume about it on this thread?

Maybe every time you see her in the office you should point your finger and shout "Liar Liar Pants On Fire!" I think that would seem to be the only thing that would make you feel better. 😂😂😂

The way she said it gave a very clear impression that her daughter was in a regular state school

Giving an overall impression, whether or not that us deliberate, is not "lying". Perhaps she was deliberately vague because you are known for being a pernickety person obsessed with catching people out.

My take on it (just a guess) is that her daughter isn't very studious and never has been, which is why she invested in a private school. (My parents did the same BTW, their nickname for me was Dolly Daydream and they thought in a class of 30 I would just have stared out of the window so they chose a tiny private school where I wouldn't be able to get away with that.) She was probably musing over her decision and wondering if it was worth the money by asking you about SATs and 11+ to consider if her daughter might have been OK in state school after all. She didn't mention private school because some people are judgy about it and tbf you do seem to be completely up your own arse about the issue.

Her daughter probably is excelling at private school because it's given her the push she needed which she may not have got in state school. "Ordinary school" is an odd turn of phrase but I think it was markedly a choice of words that allowed her to avoid using the words "state" or "private".

Based on this thread, I lie all the time. To my friend whose son has mental health issues, I talk a bit about my son's struggles.
To my friends with high achieving kids, I talk more about good things they are doing.

I think both of these facts are true, but I assume you would think that I was lying to one of them.

Are you 100% sure her daughter's school does not do SATS ? even if they don't need to - maybe they choose to do them or something similar
or
maybe they are thinking of introducing them or something similar.

have you read the school's website thoroughly ?

Well we can pick on the OP all we like and argue about SATS, the 11+ and the merits of grammar school, private school etc until the cows come home. The point is; OP is now viewing this woman as someone who may not be very trustworthy. Many aren’t. Lots of people you encounter don’t like being seen as being at a disadvantage and will embellish the truth or tell blatant lies. Sometimes you can’t believe what you’re hearing as is the case here.

You're just not getting it and clearly can't see this from a social point of view.

You interpreted the words and conversation as such - its an opinion - she sees the School as ordinary - you don't, you've decided its not a recent change.

I shall leave it there as Im beginning to feel belligerent & thats not the case for me

Maybe she is considering moving her in the next year or so to a state and therefore she will be doing SATs?

You say she talks about her daughter a lot and you know she attends school events and is very involved but then you seem confused by the two conversations. To know her involvement means you probably know which scenario is more accurate (yours or your other colleagues convo with her). I do think you've gotten the wrong end and that she was asking about SATs as she was interested, SATs are shit for Y6 so maybe she meant IF her daughter was doing them she would struggle. Whether hypothetical doing them or actually doing them if there's a move on the cards.

You still haven't said why you're bothered even if she lied? It's not to do with work or anything relevant to your relationship so what's the harm? I went out for a mums night out the other week and according to most mum's their kids don't have screen time unless it's for educational purposes, maybe 1 or 2 might not but I don't believe out of 10 kids none of them get any screen time. I did internally roll my eyes and mentioned it to DH the next day but I don't really care if they want to pretend. People talk shit sometimes, I certainly do.
