The roles of parents and teachers can sometimes be at odds unnecessarily. Neither of the roles is easy and both will benefit from respect for the other. Respect can lead to teamwork which can make the teaching experience simpler for all concerned.
Unfortunately, there seems to be a theme floating that both parents and teachers are lacking in effectiveness and receive criticism for not holding up their end of the responsibility for education. This kind of passing the baton of responsibility is not helpful as responsible adults have a tendency to do the best they can in a given set of circumstances.
Great strides can be made if parents and teachers accept that they have a real partner in each other and offer communication that is targeted to needs and goals that can be achieved when they work together.
