I would just express how I feel about the school, how much I value education, and how much I want to help keep the school a great place for our children to get their education. Then talk a little about yourself-your kids and what grades they are in, education/work background that would serve you well as an officer. You might even want to state what programs you think are particularly important.
Don't get too long winded, or flowery. Just be honest and positive.
New Kid here- I am very proud of my childrens school! My husband attended this school so it means alot to my family. However, we had a parent group years ago that had a minor explosion and disbanded. Now I am trying to bring it back and run it how a group should be run. My problem is putting on paper the best way for those who vote to vote for me! I have several rough drafts and I am not sure which one to use! It is due this Friday and I would love any suggestions. Thank you so much! This is my first time posting so I hope that it is done right!
