PTA at a School is a Unit with at least a President, Secretary, and Treasurer. More officers mean more support for the business of the unit. They plan, organize and fundraise to help with student activities. Meetings vary-consult your school.
The District level is Council and has a President, Secretary and Treasurer. Again, more officers mean more support for planning and activities. They are in charge of getting information to units and provide support to the units. Our Council also tries to work with the District to provide an activity districtwide for students to participate in. Meetings are 4 times a year.
