Other benefits Dyreng has seen through the PTO are not having to deal with the politics of a national association. “We’re just not tied to all the politics the PTA has,” said Dyreng.
...interesting, as it captures pretty well the common, subtle disconnect between PTA politics and locals. It's not content of PTA positions that is typically the issue, but more the fact that the connection to politics (by definition, politics = contentious) tends to get in way of what many groups consider their more important goals of growing parent involvement, creating community at school and supporting kids and teachers. Politics isn't exactly the recipe for kum-bay-ya togetherness and involvement.
