To buy my DD alcohol for a party?

As a teacher YOU do the advice about calling you if she needs to come home no matter what etc & this is what she says if asked.

her Dad (as the non teacher parent) does what most other parents of older 16/17 yo's does & supplies some drinks. Chosen wisely!

I’d buy a bottle of WKD / smirn off ice / few beers etc and leave them in the fridge… then if she takes it you haven’t technically supplied it 🤷‍♀️ I think it’s much better you’re in control of the type of alcohol she has. Who knows what’s in the cheap crappy vodka and she won’t know her tolerance.

So her soon to be 17 year old can't go to a house party because her mum is a teacher?! Be real.
This is a personal matter. It's her daughter. Who do you think would be filing a gross misconduct charge against her?
I'd have a very serious conversation about alcohol limits with your husband being present if that helps. Then decide as parents what the best course of action is. Being realistic she's going to drink alcohol so consuming a limited amount you have control of is far favourable than the alternative.

Teacher aspect aside it’s a tricky decision. Of course there will be copious amounts of alcohol there and highly likely drugs too. I’m a secondary teacher and house party stories make my hair curl. You definitely need conversations about what to drink / not to drink etc. And then hope for the best.

Do you teach the other kids at the party? Or do they just know you as a teacher?

Buy her a small bottle that she keeps on her at all times, and that only she can pour. No risk of spiking (and talk to her about that).Teens will drink; better to be safe and ensure it’s come from a reputable source. Let her know she can call you at any time to be picked up, no matter if drunk. She’ll be less likely to hide drinking from you, and thus safer.

It’s fine. She’ll get it from somewhere - she’s nearly 17!

Far better that you get her some low alcoholic drinks and you have an open conversation rather than she is mainlining vodka and lying about it.

It’s also important she understands alcohol and what her limits are. She may not like it.

If you're a teacher of the students at the party (which I assume you are otherwise you'd not have mentioned it?) I wouldn't risk it: you could lose your career.
Otherwise, I'd say YANBU so long as it's not excessive.

I’m also a teacher and you would be mad to do this. Anything could go wrong at the party and if it was repeated that you had supplied alcohol to minors, you’d be on a big disciplinary. Apart from that, no way in hell would I supply alcohol to my 16 year old child. Both illegal and terrible parenting.

Is she in sixth form? No issue with this if she wants to have a drink but talk to her about lining her stomach, keeping ro a limit, drinking water when she gets home etc . I usually buy my year 12 a few cans of alco pops and when she had a party here I made a big pitcher of archers and lemondade as it’s not to strong. At a sixth form party it’s hard to avoid alcohol and it’s better to be open about it.
make her pay for any booze you buy.

I agree that, as a teacher, you are in a difficult position here.
Logically, I agree with your position and when DD was about that age I turned a blind eye to her and her friend having some alcohol for a party, after a sensible chat. Unfortunately, in your position, I suspect common sense and good parenting may not be permissible.

Can’t comment from the teacher aspect but yes I did, as do all her friends parents. And anyone who thinks teens are not drinking are deluded

it’s about teaching responsibility, boundaries and knowing they can call anytime if they need to

Jesus. You’d be in very serious trouble if anyone found out. Especially if you teach any of the kids that could drink the alcohol. This is such bad judgment.

Only Buck’s Fizz if you get anything

You’re a teacher and questioning this? You could easily lose your job. By all means have the talk about responsible drinking but don’t give her anything

You’re a teacher, this would come under gross misconduct buying alcohol for underage children… I wouldn’t let her go tbh
