Of course, things have changed over the years.
When they were in elementary school, the rooms were packed. Both parents attended whenever possible, so it was standing room only. Middle school parent nights were also well attended, making it a real challenge to navigate between classrooms during the three minute passing period - the same amount of time the kids have.
High school Back-to-School Nights have been a little different. This will be our seventh year at the high school, and my husband and I have experienced both sides of the coin - classrooms that were full of anxious parents, wondering what will be expected of their child, and nearly empty rooms where maybe three other parents showed up.
Granted, sometimes a parent can't get away from work, or they have more than one child and can't be in two places at once. But this is the one time it really pays for both parents to show up. It's one evening where you get to find out what is expected of your child, what the homework policy is, whether or not extra credit will be awarded. How much are the tests worth? How much time should they be studying at home? What big project is due next week?
Try to fit Back-to-School Night into your busy schedule. It will be worth the time; and, who knows, you might even learn something!
