I understand that if your child is born after Sept, the school prefers to hold him back a year. However, my kid has just turned 3 in Nov and was bored in class so they promoted her to Pre-K and she absolutely loves it! She is stimulated with phonics and math and enjoys going to school. She is in a private American school in Singapore. However, we are planning to move to the US. What is your advice/experience with children born after Sept? Is it better to hold them back because they are younger and smaller in size or let them progress intellectually if they are able to do so?
