Every year my child was in school I was an officer, chairperson etc for the PTA.. I have made some of my very best friends through PTA. Teacher, Administrators, Parents and kids.. . We had a ton of fun , even off campus.
If you are interested. Take a look at all of the positions available in your schools PTA, and see what interest you. Then ask the current chairperson what is involved in that particular job.
For an officer position, Parliamentarian was the easiest.. You just have to attend all of the meetings and make sure the meetings follow correct procedure.. do not worry, you will be required to go to a 1 time training to learn the rules..
For a Chairperson be sure to take into consideration the time commitment. The thing I learned was for super busy parents, that wanted to be involved sometimes we would suggest they volunteer for committee that did most of its work before school starts . This way the had the summer to organize the tshirt sale, the information folders, the back to school meet and greet, whatever your school offers. ..
The other thing we suggested was for people to "Partner up with another parent" and be co chairs for some events.. One person can be the organizer and the other person can be the worker bee..
If you are really too busy to be in charge of anything.. Tell them you want them to call on you when they need help. Then give them good times of the school year or specific things you could help with here and there through out the year..
Your going to love it. It is fun to get to know the community and your child will benefit from you being involved in their school.
