Effective communication with your child's teacher is the most basic and probably most important way to make a difference in his or her success in school. This is a good chance to get a glimpse of your child's world and that alone is important to him. Attend PTA meetings, and if your schedule permits, volunteer to serve on a committee, as an officer, or as a helper for special events. If your child sees you treating school as an interesting place to be, he is more likely to feel that way also. Call the teacher when you have a pressing concern, or when it isn't so pressing, write a note.
Teachers appreciate feedback.
Volumes of vignettes can be written about children who have found success in school because they were helped by someone special who may not necessarily have been a teacher. During my youngest son's primary grade years, he struggled greatly because of problems with his fine motor skills. My wife spent two or more hours each night, five to six nights a week during this time, working with him to improve his skills and overcome his difficulties. By the middle school years, my son did much better. If it hadn't been for his mother's constant dedication and help for several years, he probably would never have caught up and been promoted.
