7 - I agree with JHB. You were not treated rightfully, however, such an issue would not generally be a PTO issue. I know that in many states, including NY, anything that has to do with the educational programs/curriculum originates with the State, who then informs the schools of what they must be incorporating into the students' everyday learning and each school does have some leeway (sp?) as to
how they go about teaching those areas.
It sounds like the issue is going nowhere with the school's staff. Maybe you could try to set a private meeting with yourself, your husband and the superintendant along with the boe's president or one of the members to at least clear up the air as to what it is you are concerned about. If that does not work you could contact your states board of education department to collect some info. See how other districts are running the program. Again, in my state and I'm guessing many others, each district has to report back to the state on how they are implementing various components of the curriculum so they may have some info for you to go by. I would not approach any of these people on the defensive though, although it may be very hard to do as you feel constantly attacked. But, you will probably get farther with a calm, pleasant "we just want to work this out" demeanor.
Just try to take a deep breath (or a couple) and gently push forward with your concern. Only my $.02 and I'm sure you'll get other advise too.
