Sue Byron has been involved in Church Aston Infant School near Newport for almost three decades.
This week, staff and students at the school said goodbye to Sue as she retires, hoping to spend more time with her own family and three grandchildren.
Jenny Griffiths, headteacher at Church Aston Infant School, said: "She has been involved in the school for 27 years – first as a parent, then a lunchtime supervisor, then a teaching assistant and finally a teacher.
"Sue has been connected to our school and dedicated to the children she has worked with over the years. The whole school will be sad to say goodbye to her."
As well as having a special presentation and assembly for Sue, the school had nominated her for the Worthy Citizen Award from Church Aston Parish Council. The chairman of the council, Simon Stacey, came out to give her the award, for services to education.
Mrs Griffiths added: "She lives in Church Aston, so has been a member of the wider community for a while. We held an assembly with a presentation and the children will be celebrating with cards and a video they made.
"Mrs Byron is the very essence of our school and she has been a great part of it for so long. She teachers reception and year one children, so she went from chalk and blackboard all the way to interactive learning.
"The children here are very fond of her and she has spent a lot of time supporting them in so many different ways. As she is the reception teacher she is their first point of contact at the school, and she couldn't be better at it."
Sue said her time at the school has been great and she will miss everyone.
"I have been really happy with my links with the school, staff, children and parents over the years," she said.
"It has been a wonderful place to work. The school is really in the heart of the community, and I will probably come back as a volunteer at some point if they will have me.
"I will miss the staff and the children so much – they became like a second family to me. But it will be great to spend more time with my own family as well. It has been nice to see the school through the past year, as it has been hard at times.
"I would recommend this school to anybody who would like to come, it is very friendly and family orientated."
