What should you do if you have to communicate a negative even to parents?
a. call the parent so that you can insert positive comments as well as the negative event
b. send the parent an email so that the parent receives the information right away
c. use a daily communication folder so the parent gets the communication that day
d. wait until a parent-teacher conference to let the parents know

Explanation:

Option A is the best action you should take to inform a negative event. This type of circumstances need to be informed personal, because emotions are involved. So, waiting a long time period to inform about it, or doing through a non-direct channel means that you don't give the importance that this event needs. Also, that wrong actions will make parents think that it's not important to you.
