For my last year experience, K1 parents can stay with their kids in the first week of class. Each K1 class is divided into 2 sessions. Class Teacher will assign students to their sessions. Parents basically can stay with their kids for the whole session in the classroom but teachers will ask the parents separate from the kids and stay at the back of the classroom. Parents are not allowed to take photo during lessons.
I think the last year arrangement is good but I am sure the arrangement of this year. And you guys will know in the Orientation Day.
