Yes, I think all kindys do that. The C&K probably do especially as their curriculm includes preparing the kids for school. I think they even cater for kids doing a second year at C&K where necessary. I wouldn't worry too much yet, she's still two years away from her school intake year and I'm sure you'll be surprised at how much more ready she seems in just a year. I am astounded by how grown up DS1 is already!
