Ballot measures fall under special laws limiting the use of school facilities and resources for campaign purposes. PTAs may advocate for or against a measure on school property providing they receive a permit for use of the school facility and equal access is provided by the school district to groups with opposing viewpoints. Check with your local school district to ensure that you stay within the rules. This does not prohibit a PTA from holding a meeting off school property or using its own resources such as PTA email, website or copy machine.
