Hi, I work in a preschool and the qualification most look for is level 3 children and young persons workforce (early years educator) diploma, some preschools/nurseries accept level 2. If you don’t already have gcse English and maths at grade c/4 or higher you will have to re take them or functional skills is also accepted for you to gain the level 3. If you have any questions feel free to ask as I still work part time in a preschool alongside my university degree.
