Going to kindergarten requires some independence. It’s important that your child can say his full name and your full name, and that he can tell an adult his phone number. Skills like being able to tell an adult that he’s not feeling well are also important. Kids need to be able to use the bathroom by themselves and take responsibility for their personal belongings, like jackets and lunch boxes.
If you’re still undecided about whether your child is ready for kindergarten, consider talking to his preschool teacher and his doctor.
