Honestly, having been the teacher in this position, no, you are not expected to give anything at all, I promise! I did used to be inundated with wine (I don’t drink!) and chocolates (I have Coeliac disease and have to be careful as not all brands are gluten free) and whilst it was very kind of parents and I was genuinely touched, it was totally unnecessary.
Getting a card written by the child was my favourite bit!
All this being said, I have private coaching in a sport and private music tuition and I will be getting some things for my coaches. For the sport coach, she is always losing her pens so I’ve got her a pack of naice pens with positivity quotes on, a fancy hardbacked notebook with her initial on for writing down individual training plans for her students and a key ring off Etsy that was customised for her. My music teacher is also a teetotal Coeliac and has a large family so I usually make up a gluten free hamper for him and the family to share - naice gluten free crackers/cheese biscuits, posh gluten free cookies, a gluten free cake of some sort and a large box of gluten free chocolates. He’s a minimalist and wouldn’t feel comfortable accepting “stuff” so I stick to food and he’s usually delighted.

Popped inside a nice card. I would have liked one of those. Stationary always went down well, even for a performing arts teacher or a festive bath bomb. One of my favourite gifts was a Poinsettia, it was only a couple of quid out of Morrisons but looked lovely at home over the festivities.
