instead of say goodbye, the principal ask my son three simple questions. he answered correct and loud. the principal said he answered very good and then no need to say goodbye. but i insisted on asking him to say bye-bye principal eventhough she answered turned away his form.
i observed very carefully and seen while waiting for the principal to come, two teachers place the forms in good order according to the seating sequence by looking at the photos. then the principal watched the no.1 baby first and observe her response towards the story telling, make some marks on the form and observe no.2 then. i can see the photos there when she was looking at my son. so it is important that the baby keep on following the teachers action at all time to make sure when the principal is oberving you the kid is responsive.
finally i saw both principals are very conscious to use one hand to cover the mark / decision at the lower bottom of the form.
