Good communication is critical to building any relationship for the benefits of all, for all. An important factor to realize is that 'Lack of communication causes most clashes and grief in all areas of life' and this can begin as early as the beginning of one's school years. Parents need to talk to teachers. Teachers need to talk to other teachers. Without communication there's a void.
Good communication can head off a potential problem.
A challenge can and should be approached jointly by teacher and parents and also if the need is there for the child's presence. New paths of communication are smoothing the way for busy parents. Some teachers now have websites and their own information where their own information is on-line. There are also those who are selecting e-mail for better communication. It is very important to be visible, introduce yourself at the beginning of the year to the teacher.
