To complain about teacher weight comments

My Daughter is in S1 aged 12 and was in biology class. Her teacher made them all weigh themselves.
My DD went through puberty age 10 and has boobs and a bum. Her BMI is 22 which is normal.
She said the teacher told them to "put 50kg down if you don't want to put your real weight as this is normal".
I am fuming about this as my DD is already weight conscious and has said she is going on a diet which I don't condone as she is healthy.
I think the teacher was very irresponsible to comment this and I sent a complaint about it to her guidance teacher which they've said they are looking in to.
I feel it's so wrong for children to compare themselves to each other as everyone is different. It's so damaging to their self esteem and at this age all girls especially have so much pressure to be thin and beautiful from the media.
Would you have complained?

I think you need to stop whining. The teacher said they didn't need to write their weight down, surely so no-one would be embarrassed.
You and your daughter need to develop resilience.

The drama around the weight is being created by parents like OP. The teacher did not single out any child at all and is not in the wrong.The only "fault" is her use of the word "normal". If trauma and triggers are what you are feeding into your girls' heads, you are going to raise very fragile kids.

Part of the learning includes collecting data yourself. Showing what outliers are, what happens if value is recorded incorrectly etc. Learning what personal data means.

Why would any mum (not every child has a mum either) provide their weight when OP is complaining about one child being triggered about being weighed once privately?

I wasn't being entirely serious.

What about short people or the freakishly tall? There is always someone who wants to make an issue out of something. Slippery slope to start pandering to it.

There’s other options to study though. If you are looking at the normal distribution of characteristics then arm span and finger span are less problematic.

That's how I read it! She WAS trying to be sensitive to avoid comparisons between individual kids.

But there’s no actual reason for them to do the activity in the first place.

Anxioustealady · 18/03/2025 13:56

Ablondiebutagoody · 18/03/2025 13:07

I am freakishly tall. Why are you being so freakishly sensitive?! Drives me nuts.

Edited

Because I think adults should be careful how they speak so children don't have lifelong insecurities.

Gosh it’s strange on here. About 75% of posters are empathetic, understanding humans and the other 25% are fucking nasty, or at the very least painfully ignorant. Aren’t people just bizarre.

It was completely unnecessary OP, I would talk to the school and I also appreciate the numerous teachers here who have also commented that it was inappropriate (the weighing AND the comment).

Justwanttocomment · 18/03/2025 13:56

I’m a science teacher and this could have been in a couple of lessons. One is when they are doing about weight being different on different planets due to gravity. We always just use a fictional person/object for this. The other one is when you can draw around your foot and work out the pressure that you exert. Again, I never get the kids to actually use their own weight, I normally give them an average to use. The very old curriculum used to get kids to work out their BMI but that’s not been done in classrooms for years. There’s just no need to get the kids to do this in a classroom.

Notaflippinclue · 18/03/2025 13:55

Stop teacher bashing - so ridiculous - you get out what you put in - so let’s all put in sensible kids - must be like walking on eggshells being a teacher these days.

I think the teacher was trying to be aware that some of the children will be self conscious of their weight so she was giving them an option. It's not like she singled your daughter out.

That's how I read it! She WAS trying to be sensitive to avoid comparisons between individual kids.

Carrotsandgrapes · 18/03/2025 13:52

I remember having to do this in school for a maths lesson (handling data or something), and the memory has stuck with me decades later. Looking back now, I wasn't overweight, but I was clearly one of the heaviest girls and at the time, like many teenage girls, I was incredibly sad and conscious about my weight. I was mortified when we all had to write our height and weight on the the board.

Basic common sense should tell teachers this kind of thing is a horrible idea.

Shelby2010 · 18/03/2025 13:50

The ‘normal’ BMI for girls doesn’t account for those that have hit puberty early & developed a ‘full’ figure.

At 11y my DD came up as overweight on the BMI chart for her age. But when I put in the same weight & height but age as 14y, she had a ‘normal’ BMI. These girls who develop early can already feel incredibly self-conscious, so teachers do need to be sensitive to this.

In this case it sounds like the teacher was trying to be helpful but the OPs DD took it that her weight was not ‘normal’ and something to be ashamed of.

picking up on some comments:

usually the point of these lessons is to show the concept of variation, that is on a group of animals the heights and weights will vary. Usually if you take the data and draw it on a graph you get a bell curve.

the teacher would not have been able to make up random data as if they did this it wouldn’t draw a bell curve when plotted and that is the point of the lesson.

there’s a whole load of biology based on this and it is something that will be on the curriculum.

most schools don’t use weight any more because of the eating disorders issue.

shoe size can be used but you don’t get quite as good a graph. Height is generally considered a better option although I have seen it done with head circumference or handspan.

This. The teacher is trying to personalise a practical lesson to teach an important science concept. Using body weight is not a good choice of variable, and easily avoided, to prevent exactly this sort of reaction.

Onlyvisiting · 18/03/2025 13:49

YANBU. There is no good reason for a teacher to be weighing children in front of each other. Especially 12 year olds, they are old enough to be body conscious but are at wildly different stages of development.

Fountofwisdom · 18/03/2025 13:48

Teacher here. I think it’s completely inappropriate to weigh children in front of each other. There will definitely have been some overweight children in that class who will have found that very upsetting and it could easily lead to bullying.

When I was a slightly chubby 9 year old, we were having a classroom discussion about the school holidays and I said that I had had chocolate Ready Brek at my GP’s house as a treat. The (young male) teacher made a smart remark, “that’s explains a lot, maybe lay of the chocolate Ready Brek.” I can feel the mortification now in my 50s. At the next breaktime, a horrible boy in the class started laughing about it and thereafter bullied me mercilessly. It was the most upsetting time of my life for the next 2 years and all triggered by a bloody teacher humiliating a little girl in front of a class.

I was bulimic. It had nothing to do with a biology lesson.

I was injured in a car crash and I was wearing a seatbelt, therefore there’s no point wearing seatbelts

hazelnutvanillalatte · 18/03/2025 13:46

The fact is that this is a vulnerable time for children and things like this can push them over the edge or cause distress. Why have them weigh themselves? They could record something else that doesn’t have this risk factor.

Eating disorders are mental health conditions, they are an attempt to control other stressful areas of your life.

Simply mentioning the concept of weight won't cause an eating disorder.

Exactly. For example, an unsettled education with many supply teachers coming and going leading to having to work extremely hard in order to keep up with studies, that could be quite a stressful area which could cause a child who sets high standards for their achievement a lot of anxiety. But it's easier to pretend that it's all caused by once seeing a picture of a skinny model or blame it on a teacher.

You don't know who had / ended up with an eating disorder though. Bulimia is especially easy to hide.

BansheeOfTheSouth · 18/03/2025 13:36

@jd88123 Going on about BMI to a 12 year old, who aren't measured normally by BMI is more damaging than being weighed once in school.

Sinkintotheswamp · 18/03/2025 13:36

MrsSunshine2b · 18/03/2025 13:27

Eating disorders are highly complicated mental illnesses with a range of causes over a period of time, linked to a need for control, self-image, and holding oneself to unrealistic standards.

They are not caused by being weighed once, or even being called overweight once.

Surely your daughter- like most human beings- is aware of her height and weight and I daresay she is aware of whether that falls into an average category for her age group and whether it is classified as healthy or not. If she doesn't, then a doctor will no doubt clue her in at some point. This biology lesson shouldn't have caused any unpleasant surprises and she was not made to reveal her weight.

We were weighed annually in PE as part of a fitness check-up which also included a range of stamina, speed, and strength exercises and body fat percentages and not one parent made a fuss, and not one child ended up with an eating disorder.

You don't know who had / ended up with an eating disorder though. Bulimia is especially easy to hide.

Are you seriously body shaming a 12 year old girl right now? Have a look at yourself

Facts aren’t body shaming?

carrotsandtomatoes · 18/03/2025 13:10

At 5’4” 54kg with a BMI of 20.4 she is at the LOW end of healthy.

you’ve proof of why these numbers are hopelessly unhelpful

Percentile charts for 12 years old are horribly inaccurate as this age group varies enormously in terms if sexual maturation. So an average is meaningless.
you clearly don’t understand BMI, percentile charts or puberty and development in terms of context. The why comments from people like you are unhelpful, incorrect and dangerous

BMI should not be used for children.
I thought that was widely known.
Children have different body compositions to adults, regardless of whether they have been through puberty. A 12 year old cannot be compared to an adult of the same height.

I knew 54kg at that height for a child would be the upper end of the % for 12 year old girls based purely on my own height and weight (as an adult).

If they're just after data sets for weight, just ask them to bring in their mum's weight, can't see that being an issue.

Why would any mum (not every child has a mum either) provide their weight when OP is complaining about one child being triggered about being weighed once privately?

YANBU. Can’t believe there are people that actually think this is ok!
