Wear the CDNIS Parent ID card at all times when visiting the School. If parents don’t have their Parent ID card or if they are visitors of CDNIS, they should register at the 9/F Security Office or the LLAC entrance upon arrival at the School. They will be issued with a visitor’s badge and should wear it at all times while on the School campus. The Parent ID cart is also a library card that allows you to sign out library books. Staff at the checkout desk in the Library will prepare an ID card for you upon request.
