Educational Societies?

So, as a theatre teacher, I suppose I could join an educational society based on English or reading since that is a major aspect of theatre, someone has to read the script. :) However, I do not think that an English/reading society would majorly benefit me or my students. For now, I will stick to joining the National Parent Teachers Association. Being a part of the PTA is a really good way to help open up lines of communication between the students' parents/guardians and the school. The PTA also helps to get educational bills and laws passed, help parents to form a learning environment, as well as a safe environment, at home, and help with anything else that makes decisions regarding the education and well-being of children.
