Too many parents call teachers to demand and accuse instead of saying that we would like to solve this problem together. Before going to the principal with a complaint, see if you can first diffuse the situation. If there are any special concerns going on in your home, do not wait for the teacher to find out through your child's acting up in class or failure to keep up with school work and poor grades. When a grandparent falls ill, if there is a health issue, financial stress, marital upheaval, problems with siblings, or any other factor that may affect your child's academic or social success, it would be wise to enlist your child's teacher as your confidential and gain her/his understanding. You can believe that most teachers would go the extra mile and extend to your child an open heart. your child an open heart.
