1. If it is a boarding school, you can ask your children to call you every day to report their study and life that day, but after a long time, your children will probably get impatient. After all, children also need space to learn, and there is no need to be too tight, which is not conducive to children's growth.
2. If the child goes home every day, you can ask about the daily school study and activities and get to know the child's situation. Sometimes if you ask too detailed questions, the children will not answer you, but will widen the gap with them.
3. Call the teacher every other week or month, so that you can probably have a chat and get a comprehensive understanding of what you want to know.
I hope the above suggestions are helpful to you.
